该问题已解决,链接地址:http://wlzjdm.iteye.com/blog/1521105

 

最近刚刚学完注解,就练习了一下下。我采用的是jsp页面里面的javascript代码访问action……

但是,我配置的注解无法将url和action进行映射,而且其中还出现了一个问题……

先看看我的那个jsp页面信息:

位置:WebRoot

内容:

 

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>


<title>My JSP 'ajaxAndStruts2.jsp' starting page</title>

<script type="text/javascript" src="../javascript/jquery-1.7.1.js"></script>
<script type="text/javascript">
	$(function() {
		$("#ok").click(function() {
			$.post("./getLover.action",{"name":$("#name").val()},function(data){
				
			},"xml");
		});
	});
</script>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

</head>

<body>
	<input type="text" id="name">
	<input type="button" id="ok" value="select">
</body>
</html>

 那么对应的Action的注解配置极其类内容为:

 

package com.dong.struts2WithOthers;

import org.apache.struts2.convention.annotation.Action;

import com.dong.util.Lover;
import com.opensymphony.xwork2.ActionSupport;

@Action(value = "getLover")
public class ByAjaxTest extends ActionSupport
{
	private String name;
	
	public String getName()
	{
		return name;
	}
	public void setName(String name)
	{
		this.name = name;
	}
	
	@Override
	public String execute() throws Exception
	{
		System.out.println("hello");
		System.out.println(name);
		if(name == "dongdong")
		{
			
			Lover lover = new Lover("xiaojing",21,"girl");
		}
		return "none";
	}
}
 

出现的错误信息

我的分析与猜想:

我写的这个Action处理类是新建了一个包com.dong.struts2WithOthers;(原来练习的时候,所有的action都位于com.dong.action;这个包下面),当我吧这个类移动到原来的包下面的时候,可以正常运行,但是为何在新的包中就无法运行呢了。

我想这个是命名空间的问题,但是吧,尝试了好多次,都没有解决。不知道该如何的设定命名空间。

 

请求朋友指教帮忙。

 

 

我不明白为何提交请求后,它会自动的去com.dong.action;(原来练习struts2的包)中去找对应的Action

 

 

注:源代码并未完全实现我的目标,只是在进行链接测试的时候,遇到了问题,就停滞了下来。。。
