1、首先把spring和struts需要的包加入到工程lib下
2、在struts-config.xml中添加插件
     

1 <struts-config>
2           <plug-in
3                       className="org.springframework.web.struts.ContextLoaderPlugIn">
4                <set-property property="contextConfigLocation"
5                       value="/WEB-INF/applicationContext.xml" />
6            </plug-in>
7       </struts-config>
8

  注：為 Struts 的 ActionServlet 裝載 Spring 應(yīng)用程序環(huán)境。就像添加任何其他插件一樣，簡單地向您的 struts-config.xml 文件添加該插件。

3、對Action進行配置
     

1<action-mappings>
2           <action path="/reg"
3                      type="org.springframework.web.struts.DelegatingActionProxy"
4                  name="regForm">
5            </action>
6      </action-mappings>
7

  注:，Struts 在運行期加載的實際上是DelegatingActionProxy ， 而
DelegatingActionProxy則實現(xiàn)了針對實際Action的調(diào)用代理，Struts最終調(diào)用的將是由Spring
管理的Action實例。

4、在beans-config.xml中配置的要點：

1     <bean id="userBLL" class="com.bll.UserBLL"></bean>
2     <bean name="/reg" class="com.web.struts.action.RegAction"
3                   singleton="false">
4          <property name="userBusiness">
5               <ref bean="userBLL" />
6           </property>
7      </bean>

注意這里的name="/reg"里的值(/reg)要和struts-config.xml里Action的path值一樣

如果啟動出現(xiàn)java.lang.NoClassDefFoundError: javax/transaction/UserTransaction 
請在lib下加入jta.jar包

5、最后寫個action測試下：

 1package com.web.struts.action;
 2
 3import javax.servlet.http.HttpServletRequest;
 4import javax.servlet.http.HttpServletResponse;
 5import org.apache.struts.action.Action;
 6import org.apache.struts.action.ActionForm;
 7import org.apache.struts.action.ActionForward;
 8import org.apache.struts.action.ActionMapping;
 9import org.apache.struts.validator.DynaValidatorForm;
10
11import com.bll.UserBLL;
12import com.vo.User;
13
14
15public class RegAction extends Action {
16    
17    private UserBLL userBusiness=null;//通過spring注入實例化對象
18
19
20    public ActionForward execute(
21        ActionMapping mapping,
22        ActionForm form,
23        HttpServletRequest request,
24        HttpServletResponse response) {
25        DynaValidatorForm regForm = (DynaValidatorForm) form;
26        
27        String email=regForm.getString("email").toString();
28        String username=regForm.get("username").toString();
29        String password=regForm.get("password1").toString();
30        User user=new User(username,password,email);
31        if(this.getUserBusiness().addUser(user)) {
32            System.out.print("success");
33        }else{
34                    System.out.print("error");
35                }
36        return null;
37    }
38
39    public UserBLL getUserBusiness() {
40        return userBusiness;
41    }
42
43    public void setUserBusiness(UserBLL userBusiness) {
44        this.userBusiness = userBusiness;
45    }
46
47    
48}
