SSH组合之Spring3整合Struts2
1、Add Spring Capabilities
2、Add struts2 Capabilities+对应版本的struts2-spring-plugin-2.2.1.jar,最好是对应版本
3、struts.xml
(1) 配置为Spring
(2) 配置Action;
<action name="*_cat" method="{1}" class="catAction">
这里class 的”catAction“需要在applicationContext.xml配置才能找到真正的class;
action类不需要继承ActionSupport,只需要有对应每个Action名称的方法;
可以在action类有相关的变量,需要get-set函数;
如果action类需要使用Dao层,则dao变量需要声明
<!-- struts2的Action --> <!-- scope默认为singleston,这里一定要设置 成prototype。这样浏览器每次请求一次,spring都会生成一个新的Action对象--> <bean id="catAction" scope="prototype" class="com.cat.action.CatAction"> <property name="catService" ref="catService"></property> </bean> <!-- 配置Dao --> <bean id="catService" class="com.cat.service.catDao"> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
struts.xml
<?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" /><!-- 配置为Spring,表该Action由Spring产生 --> <constant name="struts.devMode" value="true" /> <!-- 是否开发模式 --> <package name="cat" extends="struts-default"> <!--<global-results> <result name="exception">/exception.jsp</result> </global-results> <global-exception-mappings> <exception-mapping result="exception" exception="java.lang.Exception"></exception-mapping> </global-exception-mappings>--> <action name="*_cat" method="{1}" class="catAction"> <param name="action">{1}</param> <result>/list.jsp</result> <result name="list">list.jsp</result> </action> </package> </struts>
4、CatAction.java
package com.cat.action; import java.util.ArrayList; import java.util.List; import com.cat.bean.Cat; import com.cat.service.ICatService; public class CatAction { private ICatService catService; private Cat cat; private List<Cat> catList=new ArrayList<Cat>(); public String add(){ catService.createCat(cat); return list(); } public String list(){ catList=catService.listCats(); return "list"; } public ICatService getCatService() { return catService; } public void setCatService(ICatService catService) { this.catService = catService; } public Cat getCat() { return cat; } public void setCat(Cat cat) { this.cat = cat; } public List<Cat> getCatList() { return catList; } public void setCatList(List<Cat> catList) { this.catList = catList; } }
Done!
