java - Tomcat 无法加载我的 jsp 文件 - 服务器未找到当前表示

Question

我经常收到这个错误:

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

WARNING [http-nio-8080-exec-6] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'SpringMVC'

我正在尝试在非常简单的代码上使用 Java 配置。我有这个配置类:

 package com.kemal.config;

    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;

    @Configuration
    @ComponentScan(basePackages = {"com.kemal", "com.kemal.controllers", "com.kemal.services"})
    public class JavaConfig {

    }

这是我的 Controller 类:

package com.kemal.controllers;

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

@Controller
public class Controller1{

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

    @RequestMapping("/add")
    public String add(){
        return "display";
    }
}

Tomcat 正在将应用程序上下文部署到此 URL“/”

web.xml:

IntelliJ 可以将 Controller 类与处理程序方法中引用的 jsp 文件连接起来，但我认为服务器找不到 jsp。我错过了什么？我现在找不到解决方案。

项目结构和方面:

Answer 1

在您的配置类 javaconfig 中包含 webmvc 注释 @EnableWebMvc。它有助于扫描基于@Controller 注释的类。
