我面临的问题是我无法在点击URL-> http://localhost:9293/hello时获得任何响应

我尝试测试此简约功能时没有问题,没有错误或任何日志,但是没有运气。任何建议或线索都是最欢迎的!

如果您需要进一步的信息,请告诉我!

春季版:2.1.5。发布

OpenJDK版本:11.0.2

application.properties

server.port=9293
spring.mvc.servlet.path=/
server.error.whitelabel.enabled=false


HelloWorldController.java
    软件包com.sample.springboot.jwt.controller;

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

@RestController
public class HelloWorldController {
    @RequestMapping({ "/hello" })
    public String firstPage() {
        System.out.println("Hello World");
        return "Hello World";
    }
}


我的主类SpringBootJwtApplication
    包com.sample.springboot.jwt.demo;

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

@SpringBootApplication
public class SpringBootJwtApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootJwtApplication.class, args);
        System.out.println("From the main() method...");
    }
}


这是我的pom.xml

EDIT-1:添加我的项目结构->
java - OpenJDK 11.0.2的Spring Boot 2.0请求映射问题-LMLPHP

最佳答案

您可以尝试将spring.mvc.servlet.path更改为server.servlet.context-path吗?

检查此链接的change

更新

根据您的项目结构,控制器不会按应用程序类进行扫描。因此,您可以将Application移到com.sample.springboot包中。
