關於struts1.3中使用DispatchAction的一個問題

在action中不能有execute方法,否則其他的方法則不能執行.

如下:

package com.yanek.mvc.demo;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;

public class TestAction extends DispatchAction
{

public ActionForward execute(ActionMapping mapping, ActionForm actionform,
HttpServletRequest request, HttpServletResponse response)
throws Exception {

  UserForm form=(UserForm)actionform;

  String username=form.getUsername();
  String password=form.getPassword();

  System.out.println("parametor..."+mapping.getParameter());

  System.out.println("username..."+username);
  System.out.println("password..."+password);


  if (username.equals("admin") && password.equals("admin"))
  {
   mapping.findForward("success");
  }
  else
  {
   mapping.findForward("success");
  }



  System.out.println("action execue index...");
  return mapping.findForward("success");

}

public ActionForward add(ActionMapping mapping, ActionForm actionform,
HttpServletRequest request, HttpServletResponse response)
throws Exception {

  UserForm form=(UserForm)actionform;

  String username=form.getUsername();
  String password=form.getPassword();

  System.out.println("username..."+username);
  System.out.println("password..."+password);

  System.out.println("action add ...");

  return mapping.findForward("add");

}

public ActionForward update(ActionMapping mapping, ActionForm actionform,
HttpServletRequest request, HttpServletResponse response)
throws Exception {

  UserForm form=(UserForm)actionform;

  String username=form.getUsername();
  String password=form.getPassword();

  System.out.println("username..."+username);
  System.out.println("password..."+password);

  System.out.println("action update ...");

  return mapping.findForward("update");

}

public ActionForward delete(ActionMapping mapping, ActionForm actionform,
HttpServletRequest request, HttpServletResponse response)
throws Exception {

  UserForm form=(UserForm)actionform;

  String username=form.getUsername();
  String password=form.getPassword();

  System.out.println("username..."+username);
  System.out.println("password..."+password);

  System.out.println("action delete ...");

  return mapping.findForward("delete");

}

public ActionForward list(ActionMapping mapping, ActionForm actionform,
HttpServletRequest request, HttpServletResponse response)
throws Exception {

  UserForm form=(UserForm)actionform;

  String username=form.getUsername();
  String password=form.getPassword();

  System.out.println("username..."+username);
  System.out.println("password..."+password);

  System.out.println("action list ...");

  return mapping.findForward("list");

}

由於 action裏有execute方法,所以其他的方法都不能執行,執行其他方法時都會執行execute方法.

把execute改名或去掉即可.

配置:

訪問:

https://127.0.0.1:8080/struts1Demo/test.do?action=list

https://127.0.0.1:8080/struts1Demo/test.do?action=add

https://127.0.0.1:8080/struts1Demo/test.do?action=update

https://127.0.0.1:8080/struts1Demo/test.do?action=delete

執行相應的方法

如果有execute方法,則執行如上方法都會進入execute方法.
