Question

我一直在寻找解决此错误的方法，但无法找到答案。保持这个错误：

2018年4月6日下午1:40:36 org.springframework.web.servlet.DispatcherServlet noHandlerFound

警告：在DispatcherServlet中找不到带有URI [/ spring-tutorial /]的HTTP请求的映射，其名称为＆＃39; offers＆＃39;

我在JDK 1.8，tomcat 8.0上运行，并在最新的eclipse IDE上运行。

我的OffersController.java

package com.emenpy.spring.web.controllers;

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

@Controller
public class OffersController {

    @RequestMapping("/")
    public String showHome() {
        return "home";
    }

}

我的home.jsp

<html>
    <body>
        <h2>Hello World!</h2>
    </body>
</html>

这是我的目录树： enter image description here

Answer 1

~~你的jsp应该被称为“home.jsp”而不是“index.jsp”~~

您的扫描包名称是

<context:component-scan 
        base-package="com.emenpy.spring.web.controllers">
</context:component-scan>

当它应该是你的目录树显示

<context:component-scan 
        base-package="com.cuong.spring.web.controllers">
</context:component-scan>

因为扫描没有找到你的控制器，映射没有完成
