Question

在DispatcherServlet中找不到带有URI [/ SaturdayTest / welcome]的HTTP请求的映射，其名称为＆＃39; spring-dispatcher＆＃39;

我无法找到错误的位置。

HelloController.java

package com.prav.hellocontroller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloController  {


@RequestMapping("/welcome")
public ModelAndView helloWorld() {
    ModelAndView model=new ModelAndView("HelloPage");
    model.addObject("msg","hello world");
    return model;
}    }

HelloPage.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>

</head>
<body>
<h1>${msg}<h1>
</body>
</html>

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<display-name>SaturdayTest</display-name>

<servlet>
<servlet-name>spring-dispatcher</servlet-name>

</servlet>

<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>

弹簧调度-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-4.0.xsd">



<context:component-scan base-package="com.prav.hellocontroller">
</context:component-scan>

<bean id="viewResolver" 
class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix">
<value>/WEB-INF/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>

检查了调度程序和映射，但名称相同。可能存在问题。

Answer 1

尝试添加：

@RequestMapping("SaturdayTest")

在你的控制器上。像：

@Controller
@RequestMapping("SaturdayTest")
public class HelloController  {

让我知道这是有效的。

Answer 2

@RequestMapping（ “/ SaturdayTest /欢迎”）在您的方法上尝试使用此注释

在DispatcherServlet中找不到带有URI [/ SaturdayTest / welcome]的HTTP请求的映射，其名称为＆＃39; spring-dispatcher＆＃39;
