[摘](说的简单明了)struts+spring整合

struts+spring整合

摘自 http://www.dodoh.net/yoyo/article.asp?id=217

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

xml 代码

<struts-config>
     <plug-in
                 className="org.springframework.web.struts.ContextLoaderPlugIn">
          <set-property property="contextConfigLocation"
                 value="/WEB-INF/applicationContext.xml" />
      </plug-in>
 </struts-config>

注：为 Struts 的 ActionServlet 装载 Spring 应用程序环境。就像添加任何其他插件一样，简单地向您的 struts-config.xml 文件添加该插件。

3、对Action进行配置
    

xml 代码

<action-mappings>
          <action path="/reg"
                     type="org.springframework.web.struts.DelegatingActionProxy"
                 name="regForm">
           </action>
     </action-mappings>

注:，Struts 在运行期加载的实际上是DelegatingActionProxy ， 而
DelegatingActionProxy则实现了针对实际Action的调用代理，Struts最终调用的将是由Spring
管理的Action实例。

4、在beans-config.xml中配置的要点：

xml 代码

<bean id="userBLL" class="com.bll.UserBLL"></bean>
<bean name="/reg" class="com.web.struts.action.RegAction"
              singleton="false">
     <property name="userBusiness">
          <ref bean="userBLL" />
      </property>
 </bean>

注意这里的name="/reg"里的值(/reg)要和struts-config.xml里Action的path值一样

如果启动出现java.lang.NoClassDefFoundError: javax/transaction/UserTransaction 
请在lib下加入jta.jar包


5、最后写个action测试下：

程序代码

java 代码

package com.web.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.DynaValidatorForm;

import com.bll.UserBLL;
import com.vo.User;


public class RegAction extends Action {

    private UserBLL userBusiness=null;//通过spring注入实例化对象


    public ActionForward execute(
        ActionMapping mapping,
        ActionForm form,
        HttpServletRequest request,
        HttpServletResponse response) {
        DynaValidatorForm regForm = (DynaValidatorForm) form;

        String email=regForm.getString("email").toString();
        String username=regForm.get("username").toString();
        String password=regForm.get("password1").toString();
        User user=new User(username,password,email);
        if(this.getUserBusiness().addUser(user)) {
            System.out.print("...success...");
        }else{
                    System.out.print("...error...");
                }
        return null;
    }

    public UserBLL getUserBusiness() {
        return userBusiness;
    }

    public void setUserBusiness(UserBLL userBusiness) {
        this.userBusiness = userBusiness;
    }


}
