spring2.5整合struts2

Posted 2020-08-11

首先第一步：

导入jar包：

我的做法：

　　导入你的基本使用的spring的jar包

　　和基本使用的struts2的jar包

　　然后struts2中有一个和spring整合的jar包一定要导入，不然会抛异常。包名是这个：struts2-spring-plugin-2.3.30.jar

 

在web.xml中装载spring容器：

   <!-- 装载spring容器 -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:beans.xml</param-value>
  </context-param>
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>  

 

在web.xml中装载struts2：

<!-- 装载struts2框架 -->
  <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>

 

然后在struts2的配置文件中加入常量声明action交给spring管理：

<!-- 将action交给spring管理 -->
    <constant name="struts.objectFactory" value="spring"/>

 

当action交给spring管理之后，我们在action中的class属性可以写成spring容器中的bean的标识：

    <package name="person" namespace="/person" extends="struts-default">
        
        <!-- 这个地方的class属性变成了spring中的bean的标识 -->
        <action name="person_*" class="personAction" method="{1}">
            <result name="message" type="redirectAction">
                <param name="actionName">person_findAll</param>
                <param name="namespace">/person</param>
            </result>
            <result name="list">/person/personList.jsp</result>
        </action>
        
    </package>

 

其他地方正常开发。

 

此例子为ssh2整合的。

我整合ssh的时候出现了get方式提交中文乱码问题，试了过滤器的方式无法解决，谁看到的有方法的回复下，谢谢。要求不修改tomcat的server.xml
