嗨，我是新春Mvc

我并不是不能解决这个问题

调度器servlet（servlet context.xml）

查看页面（home.jsp）

它抛出上述错误。

您的两个方法被映射到

。但是您的URL是

/customer

此外，这没有意义：

<form action="customer" action="addCustomer">

一个窗体只能有一个操作。如果要调用addCustomer方法，则应

<form action="<c:url value='/'/>" method="post">

您还可以使用spring标记库来帮助生成URL

例如：

 <spring:url value="/model/customer" var="url" />
 <a href="${url}">Link</a>

您的组件扫描标签扫描“com.projects.model”包，但您的控制器在“com.myprojects.controller”包中更改组件扫描从

到

然后试试看

package com.myprojects.controller;

    return "home";

    dao.save(customer);
