代码重构 spring自动装配 struts动态方法

今天工作需要把原来另外一个团队的代码重构

1：原来的一个请求一个action要修改为多个请求一个aciton

修改1：在struts.xml 文件里面 增加

<constant name="struts.enable.DynamidMethodInvocation" value="true" />

然后新的action配置如下

<package name="admin" extends="json-default" namespace="/admin/dep">
        <action name="*" class="x.x.action.DepartmentAction" method="{1}">
            <result name="abc">/12.jsp</result>
        </action>
 </package>

2：修改原来spring的使用方式

遇到的问题1

在applicationContext.xml文件中新增

<context:component-scan base-package="*.*" />

 

出现问题

加入jar包 cglib-nodep-2.2.jar 问题解决

然后spring还是没有装配好

然后在寻找问题，发现还少配置

新增配置 <aop:aspectj-autoproxy proxy-target-class="true" />

然后发现有报错

加入jar包 aspectjrt-1.5.4.jar
aspectjweaver-1.6.11.jar 后不报错了，但是service还是空。

继续寻找问题。

网上搜索可能是需要struts和spring的自动装配的配置，然后在struts配置文件中增加

 <bean type="com.opensymphony.xwork2.ObjectFactory" name="spring" class="org.apache.struts2.spring.StrutsSpringObjectFactory" />
  
    <!--  Make the Spring object factory the automatic default -->
    <constant name="struts.objectFactory" value="spring" />

 

 然后报错

网上搜索后发现是少jar包

加上jar包 struts2-spring-plugin-2.1.8.1.jar 后

报错

是bean重复创建的问题

删除  <bean type="com.opensymphony.xwork2.ObjectFactory" name="spring" class="org.apache.struts2.spring.StrutsSpringObjectFactory" />
问题解决。

久违的自动装配bean成功装配好
