今天工作需要把原來另外一個團隊的代碼重構
1：原來的一個請求一個action要修改爲多個請求一個aciton
修改1：在struts.xml 文件裏面 增加
<constant name="struts.enable.DynamidMethodInvocation" value="true" />
然後新的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：修改原來spring的使用方式
遇到的問題1
在applicationContext.xml文件中新增
<context:component-scan base-package="*.*" />
出現問題

加入jar包 cglib-nodep-2.2.jar 問題解決
然後spring還是沒有裝配好
然後在尋找問題，發現還少配置
新增配置 <aop:aspectj-autoproxy proxy-target-class="true" />
然後發現有報錯

加入jar包 aspectjrt-1.5.4.jar
aspectjweaver-1.6.11.jar 後不報錯了，但是service還是空。
繼續尋找問題。
網上搜索可能是需要struts和spring的自動裝配的配置，然後在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" />
然後報錯

網上搜索後發現是少jar包
加上jar包 struts2-spring-plugin-2.1.8.1.jar 後
報錯

是bean重複創建的問題
刪除 <bean type="com.opensymphony.xwork2.ObjectFactory" name="spring" class="org.apache.struts2.spring.StrutsSpringObjectFactory" />
問題解決。
久違的自動裝配bean成功裝配好
