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 -->

    3、删除Hibernate配置文件
