运行JSP页面出错：Can't find a method to write property 'message' of type 'java.lang.Str

运行JSP页面出错：

我一共建了2个文件：

Hello.java：

package com.inspiresky.bean;

public class Hello {
 private String message = "12345";
 public String getMessage(){
 return message;

 }
 public void setMessgae(String message){
 this.message =message;
 }
}

 mytest.jsp：

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

<jsp:useBean id="hello" class="com.inspiresky.bean.Hello" scope="page" />
<jsp:setProperty name="hello" property="message" value="12345"/>

<html>
 <head>

 <jsp:getProperty name="hello" property="message" />

请问大家是什么问题？ --------------------编程问答-------------------- 没有 message属性 --------------------编程问答-------------------- 都没有给它setProperty --------------------编程问答--------------------

我标红的地方不是message属性还有 setProperty 吗？
--------------------编程问答-------------------- 你setProperty的时候对象弄错了吧 设置的不是message这个属性而是hello这个对象 --------------------编程问答-------------------- 那应该怎么改呢？ --------------------编程问答-------------------- <jsp:getProperty name="hello" property="message" /> 

name 应该对应的是类里的属性吧
也就是 message --------------------编程问答-------------------- 那你的意思是说，name="message" property="message"?

name 和 property 都是message？ --------------------编程问答-------------------- 后台是按name属性接收值的。。所以name改成message就Ok了。 --------------------编程问答-------------------- 那还用后面的property 干嘛？ --------------------编程问答-------------------- 这个值一般是用于对对象的属性赋值的。。如果你Name是一个对象，property里面指出它的属性名。在后台就会自动对这个对象的属性做赋值。应该是这样的 --------------------编程问答-------------------- Hello.java 中，

 public void setMessgae(String message){
 this.message =message;
 }

这个方法的名字出错，不是 setMessgae ， 而是 setMessage
然后最好加上无参构造函数，使当tomcat或者其他容器加载创建时不会出错！
