Question

你好，我试图创建一个简单的控制器，并将其与主类放在同一包中，但看起来好像找不到它。基本上，当我运行应用程序时，它没有映射端点。我只是不知道这是怎么回事。这是代码：

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class TestProject1Application {

    public static void main(String[] args) {
        SpringApplication.run(TestProject1Application.class, args);
    }
}


package com.example.demo.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HomeController {

    @RequestMapping(value="/hello", method = RequestMethod.GET)
    public String sayHello() {
        return "HELLO";
    }

}

项目结构和控制台：

这是我的pom.xml：

尽管在您的日志中，我没有看到“ ServletRegistrationBean”已初始化，但是您的配置没有问题。尝试再次执行Spring boot应用程序，您应该能够通过'localhost：8080 / hello'调用 HomeController 。

Spring Boot找不到任何控制器
