SSHM

一：

1、建数据库

2、建maven项目

3、添加web.xml：新建一个web项目，默认生成web.xml复制过来再删除web项目。

4、基本ssh框架pom.xml配置

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<spring.version>4.2.4.RELEASE</spring.version>
<struts2.version>2.3.15.1</struts2.version>
<Hibernate .version>4.3.11.Final</Hibernate .version>
</properties>

<groupId >org.apache.struts </groupId>

<artifactId >struts2-core </artifactId>

<version >${struts2.version} </version>

</dependency >

<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.16</version>
</dependency>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.1</version>
</dependency>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-nop</artifactId>
<version>1.6.4</version>
</dependency>

添加Log4J（日志）、SSH依赖。

Javassist是一个开源的分析、编辑和创建Java字节码的类库

二：maven webproject 整合struts2

1、web.xml 加入中心拦截器配置

编辑web应用的web.xml配置文件，配置struts2的核心Filter，这个可以从Struts2官网(http://struts.apache.org/development/2.x/docs/webxml.html)找到示例。
2前面我们提到Maven构建web项目时资源文件存放在src/main/resources目录下，但是Struts2的配置文件struts.xml默认要放在类路径下，也就是src下。
这个位置可以修改（http://www.cnblogs.com/surge/p/3581954.html），就是在web.xml中的struts2的<filter>里加入以下内容：
<init-param>
<param-name>config</param-name>
<param-value>../../resources/struts.xml</param-value>
</init-param>

配置完成后web.xml内容如下：

[java] view plain copy print ?

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name></display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
- <init-param>
- <param-name>config</param-name>
- <param-value>../../resources/struts.xml</param-value>
- </init-param>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>

2、加入log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//Apache//DTD Log4j 1.2//EN"
"http://logging.apache.org/log4j/docs/api/org/apache/log4j/xml/log4j.dtd">
<log4j:configuration>
<appender class="org.apache.log4j.ConsoleAppender" name="RootConsoleAppender">
<param name="Threshold" value="debug" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n" />
</layout>
</appender>

<category name="com.fengshu.limanman.winssage">
<priority value="debug" />
</category>

<category name="org.springframework">
<priority value="warn" />
</category>

<category name="org.hibernate">
<priority value="warn" />
</category>
<category name="org.dbunit">
<priority value="warn" />
</category>

<category name="com.mchange.v2">
<priority value="warn" />
</category>
<category name="org.apache">
<priority value="warn" />
</category>
<category name="org.logicalcobwebs">
<priority value="warn" />
</category>
<category name="com.opensymphony">
<priority value="warn" />
</category>

<root>
<level value="info" />
<appender-ref ref="RootConsoleAppender" />
</root>

</log4j:configuration>

3、引入struts2.xml

<?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">

<constant name="struts.action.extension" value="do" />

<action name="login" class="com.carson.demo.action.UserAction" method="login"> <result name="success">index.jsp</result>

<result name="login">login.jsp</result>

</action>

</package>

</struts>

（暂时注释掉pom.xml中的struts2-spring-plugin

因为还没有整合spring，如果加入struts2-spring-plugin将会报空指针异常，整合spring后需要加入此jar包，下面将不再提及。）

使用struts2注解在pom.xml里配置：

<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-convention-plugin</artifactId>
<version>${struts2.version}</version>
</dependency>

<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-json-plugin</artifactId>
<version>${struts2.version}</version>
</dependency>

4、配置jetty运行环境：在pom.xml中加入jetty插件，并且配置根目录目

<build>

<groupId> org.mortbay.jetty</groupId >

<artifactId> jetty-maven-plugin</artifactId >

</webApp>

</configuration>

</plugin>

<groupId> org.apache.maven.plugins</groupId >

<artifactId> maven-compiler-plugin</artifactId>

</configuration>

</plugin>

<groupId> org.apache.maven.plugins</groupId >

<artifactId> maven-war-plugin</artifactId>

<warName> winssage</ warName>

</configuration>

</plugin>

<groupId> org.apache.maven.plugins</groupId >

<artifactId> maven-eclipse-plugin</artifactId>

<downloadJavadocs> false</ downloadJavadocs>

</configuration>

</plugin>

<groupId> org.apache.maven.plugins</groupId >

<artifactId> maven-dependency-plugin</artifactId>

<id> install</ id>

<phase> install</ phase>

<goals>

<goal> sources</ goal>

</goals>

</execution>

</executions>

</plugin>

<groupId> org.apache.maven.plugins</groupId >

<artifactId> maven-resources-plugin</artifactId>

</nonFilteredFileExtensions>

</configuration>

</plugin>

</plugins>

</build >

三、整合spring

1、在pom.xml 加入spring依赖

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</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-jdbc</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-web</artifactId>
<version>${spring.version}</version>
</dependency>

2、web.xml加入spring监听

<context-param>
    <param-name>contextConfigLocation </param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>


<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3、添加spring配置文件 applicationContext.xml 在spring里配置bean，把bean转给spring管理

<?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:jee="http://www.springframework.org/schema/jee"
      xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:context="http://www.springframework.org/schema/context"
      xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx       http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/jee       http://www.springframework.org/schema/jee/spring-jee-2.5.xsd http://www.springframework.org/schema/context       http://www.springframework.org/schema/context/spring-context-2.5.xsd">

</beans>

Struts.xml:

<package name="test" namespace="/" extends="struts-default">
    <action name="user" class="loginController">
        <result name="success">/jsp/index.jsp</result>
    </action>
</package>

strust2整合spring时要在pom.xml中的加入struts2-spring-plugin，在运行项目测试

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>${struts2.version}</version>
</dependency>

四、spring再整合hibernate

1、在pom.xml 加入hibernate、mysql依赖

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>${Hibernate.version}</version>
</dependency>
<dependency>
    <groupId>commons-dbcp</groupId>
    <artifactId>commons-dbcp</artifactId>
    <version>1.4</version>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.6</version>
</dependency>

2、建立Hibenate.properties 属性配置文件

3、建立spring-hibernate.xml文件

4、在web.xml 加入spring-hibernate.xml

技术分享

5、在applicationContext.xml 加入Hibenate.properties 属性配置文件，并加入spring-hibernate.xml内容，并bean配置改为扫描注解文件：

技术分享

6、写model\dao\service\action 并配置注解

1）用sessionFactory.getCurrentSession()遇到问题：

org.hibernate.HibernateException: Could not obtain transaction-synchronized

解决：在applicationContext.xml中配置事物：

<bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<tx:annotation-driven transaction-manager="transactionManager" />

并在DAO实现类上标注：@Transactional

2）@Resource不能注入

原因：

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>${struts2.version}</version>
</dependency>

被注释解除注释即可
