关于此类报错，我花费两天，查阅大量资料，得到以下几种方法:

　　1. 检查action类中的返回值与struts.xml中result中的name属性是否一致

　　2.检查<form>表单中的action属性是否与struts中的name属性是否一致

　　3.如果一致，但是报错就可以往<package> 里面加入 namespace="/‘属性试试

　　4.删除struts2-convention-plugin-2.2.1.jar

还有些方法记不得了，这些都是从那些大神那儿看来的，但是依然未解决我的问题。我创建了两个web项目,一个主项目，一个对照项目，在同样的操作下，对照项目成功，主项目失败，并且无论怎么调式都失败，所以决定暂时放弃Struts框架,等开学去找大牛

，妈的真的心累啊！！！！！！！！(底层数据逻辑，业务逻辑，通过junit测试都没有问题，唯一问题就是处在struts.xml上)

下面先贴输出主项目action:

public class loginUser extends ActionSupport implements ModelDriven<User>{
/**
*
*/
private static final long serialVersionUID = -3976216323852801832L;
private User model= new User();
@Override
public User getModel() {
// TODO Auto-generated method stub
return model;
}
public String execute(String loginName,String loginPwd) throws Exception{
loginName=model.getLoginName();
loginPwd=model.getLoginPwd();
System.out.println("用户名:"+loginName);
System.out.println("密码"+loginPwd);
if (ServiceFactory.getUserServiceInstance().login(loginName, loginPwd)) {
System.out.println("success");
return INPUT;
}else {
System.out.println("faild");
return ERROR;
}
}
public void vaildate(){
if(model.getLoginName() == null){
addFieldError("loginName", "用户名不能为空");
}else if (model.getLoginPwd() == null) {
addFieldError("loginPwd", "密码不能为空");
}
}
public void addActionError(String anErrorMessage){
String s=anErrorMessage;
System.out.println(s);
}
public void addActionMessage(String aMessage){
String s=aMessage;
System.out.println(s);

}
public void addFieldError(String fieldName, String errorMessage){
String s=errorMessage;
String f=fieldName;
System.out.println(s);
System.out.println(f);

}
}

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="TMD" namespace="/" extends="struts-default">
<action name="loadUserCheck" class="struts.user.action.loginUser">
<result name="INPUT">/loginSuccess.jsp</result>
<result name="ERROR">/loginField.jsp</result>
</action>
</package>
</struts>

对照action:

package TestAction;

import com.opensymphony.xwork2.ActionSupport;

public class TestActionLoad extends ActionSupport{
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getLoginPwd() {
return loginPwd;
}
public void setLoginPwd(String loginPwd) {
this.loginPwd = loginPwd;
}
private String loginName;
private String loginPwd;
public String execute() throws Exception{
if(getLoginName().equalsIgnoreCase("ad")&&
getLoginPwd().equalsIgnoreCase("12")){
return INPUT;
}else {
return ERROR;
}
}
public void vaildate(){
if (getLoginName()==null || getLoginPwd()== null) {
addFieldError("loginName", "登陆账号不能为空");
}
}

}

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

<result name="input">/index.jsp</result>
<result name="error">/loginField.jsp</result>
