前言

       这篇主要采用Maven搭建Spring+Struts2+Hibernate的整合项目,复习一下SSH框架,虽然spring提供自己的MVC框架,但是Spring也提供和其他框架的无缝整合,采用组件形式对个框架进行管理,项目实例是按照真实企业里面的开发搭建,也是web的最后一片了。数据库使用mysql,连接池使用的是Druid数据源(这些都无关紧要,可以随时的替换),下面就将详细的介绍一下Maven搭建Spring,Struts2,和hibernation的步奏。


1、数据库设计

     数据库库表很简单,设计好数据库后,直接逆向生成实体,提高速度。数据库名为shop,只有一个表user_info。其结构如下:

2、创建Maven的webapp项目

    创建maven项目,pom.xml配置中引入所需依赖包。

     引入所需的依赖包,pom.xml内容如下:

</span>

以上就是ssh所需的所有依赖包。、


3、引入Spring

    最优先引入的是Spring框架,他是管理其他框架的容器,spring中需要配置的是自动扫描的dao,和service层的注解,然后将其注入为bean,管理。

     配置文件在src/main/java目录下,创建spring的配置文件spring.xml

     

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
			http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
			http://www.springframework.org/schema/context
			http://www.springframework.org/schema/context/spring-context-4.1.xsd">
	<!-- 加载配置文件 -->
	
	<context:property-placeholder location="classpath:config.properties"/>
	<!-- 扫描service自动注入为bean -->
	<context:component-scan base-package="org.andy.shop.service.impl,org.andy.shop.dao.impl" />

</beans>

3.1、引入日志Log4j配置

    log4j.properties配置内容如下:

   

### set log levels ###
log4j.rootLogger = INFO , C , D , E 

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/spring_struts2_Hibernate_demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/spring_struts2_Hibernate_demo_error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

3.2、项目配置文件

   添加项目的配置文件config.properties,有spring管理。

  

#application configs

#jdbc druid config
validationQuery = SELECT 1
jdbc.url = jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = root

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update


4、引入Hibernation

    Hibernation的配置主要有如下内容:数据源,SessionFactory,事务等的配置。

    spring-hibernate.xml配置如下(配置文件名可以随便起)

    

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="

		http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
		http://www.springframework.org/schema/tx 
		http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
		http://www.springframework.org/schema/aop 
		http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">

	<!-- 配置数据源 使用的是Druid数据源 -->
	<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />

		<!-- 初始化连接大小 -->

		<property name="poolPreparedStatements" value="true" />
		<property name="maxPoolPreparedStatementPerConnectionSize"
			value="33" />
		<!-- 用来检测有效sql -->
		<property name="validationQuery" value="${validationQuery}" />
		<property name="testOnBorrow" value="false" />
		<property name="testOnReturn" value="false" />
		<property name="testWhileIdle" value="true" />
		<!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 -->
		<property name="timeBetweenEvictionRunsMillis" value="60000" />
		<!-- 配置一个连接在池中最小生存的时间,单位是毫秒 -->
		<property name="minEvictableIdleTimeMillis" value="25200000" />
		<!-- 打开removeAbandoned功能 -->
		<property name="removeAbandoned" value="true" />
		<!-- 1800秒,也就是30分钟 -->
		<property name="removeAbandonedTimeout" value="1800" />
		<!-- 关闭abanded连接时输出错误日志 -->
		<property name="logAbandoned" value="true" />
		<!-- 监控数据库 -->
		<property name="filters" value="mergeStat" />
	</bean>

	<!-- 配置hibernate的SessionFactory -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<!-- 注入数据源 相关信息看源码 -->
		<property name="dataSource" ref="dataSource" />
		<!-- hibernate配置信息 -->
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">${hibernate.dialect}</prop>
				<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
				<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
				<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
			</props>
		</property>
		<!-- 扫描hibernate注解配置的entity -->
		<property name="packagesToScan" value="org.andy.shop.entity" />
	</bean>

	<!-- 配置事务管理器 -->
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

	<!-- 配置事务增强处理Bean,指定事务管理器 -->
	<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
		<!-- 配置详细事务处理语义 -->
		<tx:attributes>
			<tx:method name="insert*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />

			<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="load*" propagation="SUPPORTS" read-only="true" />

			<!-- 其他采用默认事务方式 -->
			<tx:method name="*" />

		</tx:attributes>
	</tx:advice>

	<!-- Spring aop事务管理 -->
	<aop:config>
		<!-- 配置切入点 -->
		<aop:pointcut id="transactionPointcut"
			expression="execution(* org.andy.shop.service.impl.*Impl.*(..))" />
		<!-- 指定在txAdvice切入点应用txAdvice事务增强处理 -->
		<aop:advisor pointcut-ref="transactionPointcut"
			advice-ref="transactionAdvice" />
	</aop:config>

</beans>

注意:Hibernation4使用的是SessionFactory而不是HibernationTemplate。


5、生成实体

      我们先添加实体entity,Dao,Service,Action等几个包,一般设计如下:

       技术分享     

设计好数据表之后,采用Hibernation tools自动逆向生成实体,其实体UserInfo如下:

     

package org.andy.shop.entity;

// Generated 2015-2-13 12:48:39 by Hibernate Tools 4.0.0

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

/**
 * UserInfo generated by hbm2java
 */
@Entity
@Table(name = "user_info", catalog = "shop")
public class UserInfo implements java.io.Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 5127853981202454040L;
	private int id;
	private String name;
	private Integer age;
	private String telephone;

	public UserInfo() {
	}

	public UserInfo(int id, String name) {
		this.id = id;
		this.name = name;
	}

	public UserInfo(int id, String name, Integer age, String telephone) {
		this.id = id;
		this.name = name;
		this.age = age;
		this.telephone = telephone;
	}

	@Id
	@Column(name = "id", unique = true, nullable = false)
	public int getId() {
		return this.id;
	}

	public void setId(int id) {
		this.id = id;
	}

	@Column(name = "name", nullable = false)
	public String getName() {
		return this.name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@Column(name = "age")
	public Integer getAge() {
		return this.age;
	}

	public void setAge(Integer age) {
		this.age = age;
	}

	@Column(name = "telephone")
	public String getTelephone() {
		return this.telephone;
	}

	public void setTelephone(String telephone) {
		this.telephone = telephone;
	}

}

6、创建Dao层

    我们采用面向接口编程,所以先设计接口,在写dao的实现类,其理,同样适用于service层。

6.1、Dao层接口

   我们先定义一个通用的GenericDao接口,如下:

   

package org.andy.shop.dao;

import java.io.Serializable;
import java.util.List;

/**
 * 创建时间:2015-2-11 下午2:26:42
 * 
 * @author andy
 * @version 2.2
 * 
 * Dao通用接口
 */

interface GenericDao<T, PK extends Serializable> {
	
	T load(PK id);
	
	T get(PK id);
	
	List<T> findAll();
	
	void persist(T entity);
	
	PK save(T entity);
	
	void saveOrUpdate(T entity);
	
	void delete(PK id);
	
	void flush();
}

   具体的UserInfo的Dao接口UserInfoDao如下:

  

package org.andy.shop.dao;

import org.andy.shop.entity.UserInfo;

/**  
 * 创建时间:2015-2-13 下午12:49:55  
 * @author andy  
 * @version 2.2  
 * 描述: userDao 
 */

public interface UserInfoDao extends GenericDao<UserInfo, Integer> {

}

6.2、Dao层实现类

   UserInfo的Dao层实现类UserInfoDaoImpl如下:

package org.andy.shop.dao.impl;

import java.util.List;

import org.andy.shop.dao.UserInfoDao;
import org.andy.shop.entity.UserInfo;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

/**
 * 创建时间:2015-2-13 下午12:51:47
 * 
 * @author andy
 * @version 2.2 
 * 描述: dao实现类
 */

@Repository("userInfoDao")
public class UserInfoDaoImpl implements UserInfoDao {

	@Autowired
	private SessionFactory sessionFactory;

	private Session getCurrentSession() {
		return this.sessionFactory.getCurrentSession();
	}

	@Override
	public UserInfo load(Integer id) {
		return (UserInfo) this.getCurrentSession().load(UserInfo.class, id);
	}

	@Override
	public UserInfo get(Integer id) {
		return (UserInfo) this.getCurrentSession().get(UserInfo.class, id);
	}

	@SuppressWarnings("unchecked")
	@Override
	public List<UserInfo> findAll() {
		List<UserInfo> userInfos = this.getCurrentSession()
				.createQuery("from UserInfo").list();
		return userInfos;
	}

	@Override
	public void persist(UserInfo entity) {
		this.getCurrentSession().persist(entity);

	}

	@Override
	public Integer save(UserInfo entity) {
		return (Integer) this.getCurrentSession().save(entity);
	}

	@Override
	public void saveOrUpdate(UserInfo entity) {
		this.getCurrentSession().saveOrUpdate(entity);
	}

	@Override
	public void delete(Integer id) {
		UserInfo entity = this.load(id);
		this.getCurrentSession().delete(entity);
	}

	@Override
	public void flush() {
		this.getCurrentSession().flush();

	}

}

我们采用@Repository注解将其注入为dao的bean,交由spring管理。


7、创建Service层

   Service层同理按照面向接口编程。

7.1、Service层接口

   UserInfo层接口UserInfoService如下:

  

package org.andy.shop.service;

import java.util.List;

import org.andy.shop.entity.UserInfo;

/**  
 * 创建时间:2015-2-13 下午1:00:51  
 * @author andy  
 * @version 2.2  
 * 描述: 
 */

public interface UserInfoService {
	UserInfo load(Integer id);

	UserInfo get(Integer id);

	List<UserInfo> findAll();

	void persist(UserInfo entity);

	Integer save(UserInfo entity);

	void saveOrUpdate(UserInfo entity);

	void delete(Integer id);

	void flush();
}

7.2、service层实现类

   service层我们使用@Service注解将其注入为bean。

  

package org.andy.shop.service.impl;

import java.util.List;

import org.andy.shop.dao.UserInfoDao;
import org.andy.shop.entity.UserInfo;
import org.andy.shop.service.UserInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * 创建时间:2015-2-13 下午1:03:47
 * 
 * @author andy
 * @version 2.2 描述:
 */
@Service("userInfoService")
public class UserInfoServiceImpl implements UserInfoService {

	@Autowired
	private UserInfoDao userInfoDao;

	@Override
	public UserInfo load(Integer id) {
		return null;
	}

	@Override
	public UserInfo get(Integer id) {
		return userInfoDao.get(id);
	}

	@Override
	public List<UserInfo> findAll() {
		return userInfoDao.findAll();
	}

	@Override
	public void persist(UserInfo entity) {
		userInfoDao.persist(entity);
	}

	@Override
	public Integer save(UserInfo entity) {
		return userInfoDao.save(entity);
	}

	@Override
	public void saveOrUpdate(UserInfo entity) {
		userInfoDao.saveOrUpdate(entity);
	}

	@Override
	public void delete(Integer id) {
		userInfoDao.delete(id);
	}

	@Override
	public void flush() {
		userInfoDao.flush();
	}

}

8、单元测试Spring和Hibernation框架的整合

   以上,spring和Hibernation框架就算是整合完成了,我们需要测试一下是否整合成功,事务是否起作用等,所以我们需要在src/test/java源目录中编写测试类,进行测试:

   我们创建了TestUserService类,进行单元测试:

  技术分享

 TestUserService内容如下:

  

package org.andy.shop.service;

import org.andy.shop.entity.UserInfo;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;

/**
 * 创建时间:2015-2-13 下午3:31:07
 * 
 * @author andy
 * @version 2.2
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring.xml",
		"classpath:spring-hibernate.xml" })
public class TestUserService {

	private static final Logger LOGGER = Logger
			.getLogger(TestUserService.class);

	@Autowired
	private UserInfoService userInfoService;

	@Test
	public void save() {
		UserInfo userInfo = new UserInfo();
		userInfo.setName("zty");
		userInfo.setAge(23);
		userInfo.setTelephone("13212221333");
		Integer id = userInfoService.save(userInfo);
		JSON.toJSONString(id);
	}

}

我们需要引入springjunit的包,将spring配置加载,如果单元测试成功,那么项目搭建已经成功了一半了。


9、引入Struts2

  配置Struts框架的配置文件,Struts2不同于前面的框架,其配置文件名必须为struts.xml,内容如下:

   

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
	<!-- 指定由spring负责action对象的创建 -->

	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<!-- Action名称中是否还是用斜线 -->
	<constant name="struts.enable.SlashesInActionNames" value="false" />
	<!-- 允许标签中使用表达式语法 -->
	<constant name="struts.tag.altSyntax" value="true" />
	<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
	<constant name="struts.dispatcher.parametersWorkaround" value="false" />

	<!-- 用于CRUD Action的parent package -->
	<package name="crud-default" extends="convention-default">
		<!-- 基于paramsPrepareParamsStack, 增加store interceptor保证actionMessage在redirect后不会丢失 -->
		<interceptors>
			<interceptor-stack name="crudStack">
				<interceptor-ref name="store">
					<param name="operationMode">AUTOMATIC</param>
				</interceptor-ref>
				<interceptor-ref name="paramsPrepareParamsStack" />
			</interceptor-stack>
		</interceptors>
		<default-interceptor-ref name="crudStack" />
	</package>

	<!-- 使用Convention插件,实现约定大于配置的零配置文件风格. 特殊的Result路径在Action类中使用@Result设定. -->

</struts>

上面配置的比较详细,可以按照实际项目,做一下筛检。


10、配置web容器web.xml

    web.xml是web项目的核心,里面配置了容器启动是的加载文件,以及监听器,过滤器等内容,所以需要我们配置对个框架的启动,加载。其内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">

	<display-name>spring_struts2_Hibernate_demo</display-name>

	<!-- spring 和  Hibernate的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
		     classpath:spring.xml
		     classpath:spring-hibernate.xml
	    </param-value>
	</context-param>

	<!-- 编码设置 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- openSessionInView配置 作用是延迟session关闭到view层 -->
	<filter>
		<filter-name>openSessionInViewFilter</filter-name>
		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
		<init-param>
			<param-name>singleSession</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>

	<!-- 监听servletContext,启动contextConfigLocation中的spring配置信息 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 防止spring内存溢出监听器 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>

	<!-- Struts2 filter -->
	
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>
	
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>


	<filter-mapping>
		<filter-name>openSessionInViewFilter</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>

	<!-- 配置session超时时间,单位分钟 -->
	<session-config>
		<session-timeout>30</session-timeout>
	</session-config>

	<welcome-file-list>
		<welcome-file>/index.jsp</welcome-file>
	</welcome-file-list>
</web-app>


注意:上面Hibernation4和3还是有点区别的。


11、创建控制层Action

    控制层Struts2我们采用annotation 约束注解方式实现action的零配置,需要我们在WEB-INF下创建content目录(必须是content),里面存放是视图层jsp。

    UserinfoAction内容如下:

   

package org.andy.shop.action;

import java.util.List;

import org.andy.shop.entity.UserInfo;
import org.andy.shop.service.UserInfoService;
import org.andy.shop.utils.AjaxUtil;
import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.convention.annotation.Namespace;
import org.springframework.beans.factory.annotation.Autowired;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Preparable;

/**
 * 创建时间:2015-2-13 下午2:49:22
 * 
 * @author andy
 * @version 2.2 描述: user的Action
 */
@Namespace("/user")
public class UserinfoAction extends ActionSupport implements
		ModelDriven<UserInfo>, Preparable {
	private static final long serialVersionUID = -2301203156032690317L;

	private static final Logger LOGGER = Logger.getLogger(UserinfoAction.class);
	private Integer id;
	private UserInfo userInfo;
	private List<UserInfo> userInfos;

	@Autowired
	private UserInfoService userInfoService;

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public UserInfo getUserInfo() {
		return userInfo;
	}

	public void setUserInfo(UserInfo userInfo) {
		this.userInfo = userInfo;
	}

	public List<UserInfo> getUserInfos() {
		return userInfos;
	}

	public void setUserInfos(List<UserInfo> userInfos) {
		this.userInfos = userInfos;
	}

	@Override
	public UserInfo getModel() {
		if (null != id) {
			userInfo = userInfoService.get(id);
		} else {
			userInfo = new UserInfo();
		}
		return userInfo;
	}

	@Override
	public String execute() throws Exception {
		LOGGER.info("查询所有用户");
		userInfos = userInfoService.findAll();
		return SUCCESS;
		
	}

	public void detail() {
		String id = ServletActionContext.getRequest().getParameter("id");
		LOGGER.info("查看用户详情:" + id);
		userInfo = userInfoService.get(Integer.valueOf(id));
		AjaxUtil.ajaxJSONResponse(userInfo);

	}

	@Override
	public void prepare() throws Exception {
		
	}

}

按照约束原则,上面success是会跳转到content下的/user/userinfo.jsp视图。

注意:如果上述的UserinfoAction写出了UserInfoAction,那么对应的视图为/user/user-info.jsp,对应的Action为user-info.action


12、创建视图层

   视图userinfo.jsp内容如下:

   

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<base href="<%=basePath%>" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>
<title>userInfo</title>
</head>
<body>
	全部用户信息:
	<c:forEach items="${ userInfos}" var="user">
	    <div>  姓名:${user.name }   年龄:${user.age }    电话: ${user.telephone }  <a target="_blank" href="user/userinfo!detail.action?id=${user.id}">json详情</a></div>
	</c:forEach>

</body>
</html>

通过这个视图,我们可以测试UserinfoAction中的两个url。


13、部署服务器测试

   使用Maven打包部署:clean compile  package

    测试   http://localhost:8080/spring_struts2_Hibernate_demo/user/userinfo.action

            技术分享

   json返回数据  http://localhost:8080/spring_struts2_Hibernate_demo/user/userinfo!detail.action?id=1

         技术分享

OK,到此为止Spring+Struts2+Hibernate全部搭建完成。
