  • Spring和Struts2整合

    Spring整合Struts2

       步骤:1、导入Struts2jar相关包,并且导入Struts2-Spring-plugin-2.0.11.2.jar

          2、配置xml文件:配置Struts2过滤器和Spring上下文参数和监听器

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="3.0" 
        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_3_0.xsd">
      <display-name></display-name>    
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
      <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>/*</url-pattern>
      </filter-mapping>
      <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>
      <listener>
        <listener-class>com.pb.listener.SpringContextLoaderListener</listener-class>
      </listener>
      </web-app>

          3、配置Spring配置文件。

                主要用来配置Struts2中的Action,之后,此Action需要被Struts2配置文件调用。例如:

      

    <!-- 配置一个Struts2中的Action的Bean示例 -->
        <bean id="loginAction" class="Action.LoginAction">
            <property name="userDao">
                <ref local="userDao"/>
            </property>
        </bean>

          4、配置Struts2配置文件。

                1、在Struts2配置文件中,添加一个<constent>标签,指定Action的创建工厂由Spring来完成:

                  <constant name="struts.objectFactory" value="spring"></constant>

                2、调用Spring配置文件中的配置的Action Bean,其中,class属性指向Spring配置文件中的Bean id

    <?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
    <struts>
        <constant name="struts.objectFactory" value="spring"></constant>
        <package name="default" namespace="/" extends="struts-default">
            <action name="login" class="loginAction" >
                <result name="success">index.jsp</result>
            </action>
        </package>
    </struts>  

          5、Struts的Action类需要继承ActionSupport

                创建Action类的时候需要继承ActionSupport类

    Spring整合Hibernate

        1、导入Spring和Hibernate所需jar包

        2、注入SessionFactory

              Spring配置数据源后,可以通过配置org.springframework.orm.hibernate4.LocalSessionFactoryBean来配置SessionFactory,从而完成整合。示例:

    <?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:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:tx="http://www.springframework.org/schema/tx"
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
        
        <!-- 说明:下面有的Bean配置提供了多种方案,请根据需要采用某一种(别忘了注释掉其他同类方案) -->
    
        <!-- 自动扫描Spring注解配置 -->
        <context:component-scan base-package="com" />
    
        <!-- 自动加载属性配置文件 -->
        <context:property-placeholder location="classpath:jdbc.properties" />
        
        
    
        <!-- 配置数据源:方法一,使用C3P0方式(推荐) -->
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" 
            destroy-method="close" 
            p:driverClass="${jdbc.driverClassName}"
            p:jdbcUrl="${jdbc.url}" 
            p:user="${jdbc.username}" 
            p:password="${jdbc.password}" />
    
        <!-- 配置数据源:方法二,使用DBCP方式(不推荐) -->
        <!-- 
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 
            destroy-method="close" 
            p:driverClassName="${jdbc.driverClassName}" 
            p:url="${jdbc.url}" 
            p:username="${jdbc.username}" 
            p:password="${jdbc.password}" />
         -->
    
        <!-- 配置数据源:方法三,使用JNDI方式 -->
        <!-- 
        <jee:jndi-lookup id="dataSource" jndi-name="${jndi.name}" />
         -->
         
        
    
        <!-- 配置Hibernate的数据源代理工厂:方法一,使用p属性通配符,按文件名搜索匹配的映射文件 -->
        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
            p:dataSource-ref="dataSource" p:mappingLocations="classpath*:/com/**/*.hbm.xml">
            <property name="hibernateProperties">
