Spring与Struts2集成开发


Struts2和Spring都是不错的开源框架,Spring与Struts2集成开发,把二者结合在一起使用,开发效果更佳,效率杠杠的。下面介绍一下如何Spring与Struts2集成在一起开发。分七步战略:
1、添加Struts2 支持jar包  ;注意:加上一个Struts-spring-plugin(集成)插件包
2、添加spring 支持jar包
3、编写struts.xml配置文件
	注意:Action是交由Spring管理;所以action class属性应和spring 中配置的Action  Bean ID一致
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
    <struts>
        <package name="default" namespace="/" extends="struts-default">
            <!-- 配置用户ACTION 
                Action由Spring维护
                class就是spring中Action  Bean的ID
            -->
            <action name="useraction*" class="useraction" method="{1}">
                <result name="success" type="redirect">success.jsp</result>
                <result name="login" type="redirect">index.jsp</result>
            </action>
            
        </package>
    </struts>

 


4、在web.xml中配置struts2过滤器
<?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">
    <!-- 配置struts2核心过滤器 -->
    <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>
    
    <!-- 指定spring配置文件所在位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 配置sprig监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <welcome-file-list>
      <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

 


	
5、编写spring配置文件applicationContext.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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
    
    <!-- 配置持久化层 new userdao()-->
    <bean id="userdao" class="DAO.impl.UserDaoimpl" scope="prototype"></bean>
  
      <!-- 创建业务层 new userbiz() -->
      <bean id="userbiz" class="BIZ.impl.UserBizimpl" scope="prototype">
          <!-- 注入持久化层 DAO
              IUuserDao userdao = new userdao()
          -->
          <property name="userdao" ref="userdao"></property>
      </bean>
      
      <bean id="useraction" class="Action.UserAction" scope="prototype">
          <!-- 注入业务层BIZ 
              IUserBiz userbiz = new UserBiz()
          -->
          <property name="userbiz" ref="userbiz"></property>
      </bean>

</beans>

 


6、在web.xml中配置spring监听器和指定配置文件所在位置(注:如果其文件在WEB-INF/applicatonContext.xml下的话就不需要指定)
    
    <!-- 指定spring配置文件所在位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 配置sprig监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

 


7、编写三层结构;通过spring依次注入各依赖对象
	BIZ 中注入 DAO层
	Action 层中注入  BIZ层
