我的任务
分享大侠们求助啊，谢谢啊，我的Struts2类型转换问题No result defined for action ** and result input
我的struts.xml文件：
<struts>
<package name="struts2" extends="struts-default" >
<action name="userAction" class="action.UserAction">
<result name="success">/loginSuccess.jsp</result>
</action>
</package>
</struts>
我的UserAction文件：
package action;
import com.opensymphony.xwork2.ActionSupport;
import entity.User;
public class UserAction extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 1L;
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
@Override
public String execute() throws Exception{
System.out.println("userName:"+user.getUserName());
System.out.println("userPassword:"+user.getUserPassword());
return SUCCESS;
}
}
login.jsp文件：
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<%@ taglib prefix="s" uri ="/struts-tags" %>
<html>
<head><title>类型转换器</title></head>
<body>
<h1>使用逗号隔开用户名和密码信息</h1>
<form action="userAction" method="post" >
userinfo:<input type="text" name="user"><br>
<input type="submit" value="submit">
</form>
</body>
</html>
loginSuccess.jsp文件：
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<%@ taglib prefix="s" uri ="/struts-tags" %>
<html>
<body>
<s:property value="user" />
</body>
</html>
其他的文件要看么？我放下面吧

[Quote=引用 2 楼 的回复:]
userinfo:<input type="text" name="user.userName"><br>
你user是个对象
[/Quote]
想取user对象中的userName???这种写法行不通.
直接在action里写set/get吧.
userinfo:<input type="text" name="user.userName"><br>

userinfo:<input type="text" name="user"><br> 这个地方 应为你的user是对象 所以要对象.属性user.userName 或者你这样
private String name;
public void setName(String name){
user.setUserName(name);
}
public String getName(){
return user.getUserName();
}

换这种试试：
public class MyConverter extends StrutsTypeConverter {
public Object convertFromString(Map context, String[] values, Class toClass) {
.....
}
public String convertToString(Map context, Object o) {
.....
}
}
public class MyConverter extends StrutsTypeConverter {
public Object convertFromString(Map context, String[] values, Class toClass) {
.....
}
public String convertToString(Map context, Object o) {
.....
}
}

input里的name属性是参数，按你想的你想用参数获取方法，怎么可能啊

我这里可是要用到类型转换方法的，你那么一修改，貌似就不通过类型转换了啊

UserAction类里定义userName，并提供get，set方法

我按楼上的修改，倒是没有错误提示了，可是也不是我想要的结果，运行结果是：
entity.User@2d17c254
我还要怎么改呢？
entity.User@2d17c254
我还要怎么改呢？

转换文件UserConverter：
package util;
import java.util.Map;
import java.util.StringTokenizer;
import entity.User;
import ognl.DefaultTypeConverter;
public class UserConverter extends DefaultTypeConverter {
public Object convertValue(Map context,Object value,Class toType){
if(toType == User.class)
{
String[] str=(String[])value;
String firstValue=str[0];
StringTokenizer st=new StringTokenizer(firstValue,";");
String userName=st.nextToken();
String userPassword=st.nextToken();
User user=new User();
user.setUserName(userName);
user.setUserPassword(userPassword);
return user;
}else if(toType==String.class){
User user=(User)value;
String userName=user.getUserName();
String userPassword=user.getUserPassword();
String userInfo="userName:"+userName+",userPassword:"+userPassword;
return userInfo;
}
return null;
}
}
UserAction-converter.properties文件：
user=util.UserConverter
后面这两个就不用看了吧。。
User.java:
public class User {
private String userName;
private String userPassword;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPassword() {
return userPassword;
}
public void setUserPassword(String userPassword) {
this.userPassword = userPassword;
}
}
web.xml配置：
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
该有的jar包也都引进去了啊，为什么会发出错误呢？
错误信息具体如下：
HTTP Status 404 - No result defined for action action.UserAction and result input
