昨天在使用的Struts2做练习时出现了这个错误啊，控制台提示Could not find action or result，下面是报出的具体细节，我搜索了很多的文档，花费很多时间,终于找到了我的错误原因。在这里分享一下，希望大家可以很快的解决这个问题，少走一些弯路。

下面是控制台输出的异常：

我的jsp页面如下:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script type="text/javascript"
	src="${pageContext.request.contextPath}/js/jquery-1.4.min.js"></script>
<script type="text/javascript">
	$(document).ready(function() {
		$("#verifyImage").click(function() {
			$(this).attr("src", "user/checkCode?time=" + new Date().getTime());
		});
		$("#loginButton").click(function() {
			var err = $("#err");
			if ($("#checkCode").val() == "") {
				err.text("验证码为空！");
				return false;
			}
		});
	});
</script>
</head>
<body>
	<form action="user/login" method="post">
		<input type="text" name="checkCode" id="checkCode" /> <img
			src="user/checkCode" id="verifyImage" width="60" height="25"
			border="1" alt="看不清?换一张" title="看不清?换一张" /> <br /> <input
			type="submit" value="登录" id="loginButton"> <span id="err"
			style="color: red;">${error}</span>
	</form>
</body>
</html>

Action如下:

package com.ksjl.action.user;

import com.ksjl.action.BaseAction;

/**
 * LoginAction
 * 
 * @version 1.0 2013-08-15 23:56
 * @author 旷世绝伦
 */

public class LoginAction extends BaseAction {

	private static final long serialVersionUID = 1L;

	private String checkCode;// 用户输入的验证码

	public String getCheckCode() {
		return checkCode;
	}

	public void setCheckCode(String checkCode) {
		this.checkCode = checkCode;
	}

	public String execute() {
		if (checkCode != session.get("checkCode")) { // 判断验证码是否正确
			request.put("error", "验证码错误!");
			return "fail";
		}
		return SUCCESS;
	}

}

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" ".1.dtd">
<struts>
	<package name="csdn" namespace="/user" extends="struts-default">
		<action name="checkCode" class="com.ksjl.action.user.CheckCodeAction">
			<result name="success" type="stream">
				<param name="inputName">imageStream</param>
			</result>
		</action>
		<action name="login" class="com.ksjl.action.user.LoginAction">
			<result name="success">/LoginSuccess.jsp</result>
			<result name="fail">/login.jsp</result>
		</action>
	</package>
</struts>

出现这个错误之后我分别对jsp页面，action代码和struts.xml进行了检验。

首先我查看了jsp中的form表单中的代码，确认form表单的action和struts.xml中的action相对应。

第二检查struts.xml中的result和action类中的返回值是否一样，进行统一的编写。

第三我测试了Action 是能够访问到的,于是得出结论是struts2没有找到对应的结果页面。

后来经过不断的查阅和调试终于找到问题所在：

struts-convention-plugin.jar文件，这个jar保具体的功能可能是更改了默认的返回路径。

我在tomcat的webapps下找到项目将WEB-INF下的lib的 struts-convention-plugin.jar文件删除

Struts就能正常跳转页面了！
