本文主要介绍利用maven搭建spring4+hibernate4开发环境。
首先我们创建一个maven项目,具体步骤就不详细介绍了,看看我们pom.xml文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.lifesense</groupId> <artifactId>springmvc4-hibernate4</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>springmvc4-hibernate4 Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <spring.version>4.0.6.RELEASE</spring.version> <hibernate.version>4.3.6.Final</hibernate.version> <mysql.version>5.1.6</mysql.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- 添加Log4J依赖 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency> <!-- servlet --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <scope>provided</scope> <version>3.1.0</version> </dependency> <!-- Spring 4 dependencies --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!-- 测试组件 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version> ${spring.version} </version> <scope>provided</scope> </dependency> <!-- AspectJ 支持spring切面编程 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.7.4</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.4</version> </dependency> <!-- hibernate --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>${hibernate.version}</version> </dependency> <!--mysql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <!-- dbcp连接池 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- Jackson --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- json --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.6.2</version> </dependency> <!-- 用于文件上传 --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.2</version> </dependency> </dependencies> <build> <finalName>springmvc4-hibernate4</finalName> </build> </project>
pom文件中主要配置一些需要依赖的包,maven会帮我们管理这些包
解下来看看web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name>Archetype Created Web Application</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:context-servlet.xml</param-value> </context-param> <!-- 配置前端分发器 --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:context-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <!-- 设置编码格式 --> <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> <!-- <async-supported>true</async-supported> --> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class> org.springframework.orm.hibernate4.support.OpenSessionInViewFilter </filter-class> <init-param> <param-name>sessionFactoryBeanName</param-name> <param-value>sessionFactory</param-value> </init-param> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name> flushMode </param-name> <param-value>AUTO </param-value> </init-param> </filter> <filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
具体我就不做过多的解释了,解下来是hibernate-config.xml的
<?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" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd"> <!-- 读取配置文件 --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 配置数据库连接池 dbcp --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="maxActive" value="${jdbc.maxActive}" /> <property name="maxIdle" value="${jdbc.maxIdle}" /> <property name="maxWait" value="${jdbc.maxWait}" /> <property name="removeAbandoned" value="${jdbc.removeAbandoned}" /> <property name="removeAbandonedTimeout" value="${jdbc.removeAbandonedTimeout}" /> <property name="logAbandoned" value="${jdbc.logAbandoned}" /> <property name="validationQuery" value="${jdbc.validationQuery}" /> <property name="testOnBorrow" value="${jdbc.testOnBorrow}" /> </bean> <!-- Hibernate session factory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property> <property name="packagesToScan" value="com.lifesense.entity" /> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事务,hibernate必须配置事务 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="get*" read-only="true" /> <tx:method name="find*" read-only="true" /> <tx:method name="*" read-only="false" /> </tx:attributes> </tx:advice> <aop:config expose-proxy="true"> <!-- 只对业务逻辑层实施事务 --> <aop:pointcut id="txPointcut" expression="execution(* com.lifesense.service..*.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" /> </aop:config> </beans>
注意我们使用了申明式事务,hibernate4必须配置事务才能使用。
接下来看看spring的配置文件
<?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" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <import resource="classpath*:hibernate-config.xml" /> <!-- 注解扫描包 --> <context:component-scan base-package="com.lifesense" /> <context:annotation-config /> <!-- 开启AOP注解扫描 --> <aop:aspectj-autoproxy proxy-target-class="true" /> <!-- 启动JSON格式的配置 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" /> </list> </property> </bean> <!-- 定义视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/view/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 支持文件上传 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8" /> <property name="maxUploadSize" value="1048576000" /> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
环境配置基本完毕我们测试一下,写了一个user类
package com.lifesense.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
/**
* 用户实体类
* @author Administrator
*
*/
@Entity
@Table
public class User {
//主键id
@Id
@GeneratedValue
private Integer id;
private String name;
private Integer age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
接下来是一个dao
package com.lifesense.dao.impl; import org.springframework.stereotype.Repository; import com.lifesense.dao.UserDao; import com.lifesense.entity.User; @Repository public class UserDaoImpl extends BaseDaoImpl<User> implements UserDao{ }
service
package com.lifesense.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.lifesense.dao.UserDao; import com.lifesense.entity.User; import com.lifesense.service.UserService; @Service public class UserServiceImpl implements UserService{ @Resource private UserDao userDao; /** * 获取用户 * @param id 用户id * @return */ public User getUser(Integer id){ return userDao.get(User.class, id); } /** * 增加一个用户 * @param user 用户实体 */ public void saveUser(User user){ userDao.save(user); } }
controller
package com.lifesense.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import com.lifesense.entity.User; import com.lifesense.service.UserService; /** * 用户控制器 * @author Administrator * */ @Controller @RequestMapping("/user") public class UserController { @Resource private UserService userService; /** * 获取用户 * @ResponseBody表示异步请求 * @return */ @RequestMapping(value="/get_user",method=RequestMethod.GET) @ResponseBody public User getUser(@RequestParam("id") Integer id){ return userService.getUser(id); } /** * 添加一个用户,这里使用json格式传递参数 * @param user * @return */ @RequestMapping(value="/save_user",method=RequestMethod.POST) @ResponseBody public String saveUser(@RequestBody User user){ userService.saveUser(user); return "success"; } }
好了我们通过postman测试一下,OK
