#struct2 ajax

可能我的code 不是很好，只是作为一个参考，我也是初学者

之前用ajax 都有配合用struct 应为strcut 拦截功能和返回物理视图，

但是，ajax 读取一个放回数据时候，他便直接放回所以我的代码值返回out 的数据再返回SUCCESS 因为根本访问不到所以都无所谓

package org.com.ssh.email_tool;

import java.io.PrintWriter;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.interceptor.ServletResponseAware;
import org.com.ssh.hibernate.service.DabaseOperate;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.opensymphony.xwork2.Action;

public class FindEmail implements Action,ServletResponseAware{


   private String email;
   private HttpServletResponse response;

   public String getEmail() {
       return email;
   }

   public void setEmail(String email) {
       this.email = email;
   }

   @Override
   public String execute() throws Exception {
       // TODO Auto-generated method stub

            setEmail("960603374@qq.com");
           AbstractApplicationContext app =new ClassPathXmlApplicationContext("beans.xml");
           DabaseOperate da=app.getBean("dabaseoperate",DabaseOperate.class);
           app.registerShutdownHook();
           PrintWriter out =response.getWriter();
           String info=da.FindEmail(this.email)+"";
           out.println(info);
           System.out.println(info);
           out.flush();
           out.close();
           return SUCCESS;


       }

@Override
public void setServletResponse(HttpServletResponse arg0) {
   // TODO Auto-generated method stub
   this.response=arg0;



}

}
