Java 404RESTAPI与springboot

我在这方面已经有几天的时间了，虽然我知道他们可能会看到问题的标题被重复，但事实是，我已经尝试了几种对其他人有效但对我无效的解决方案。最有可能的事情是，这真的很愚蠢，我还没有看到它，但我的边缘

这是我的pom.xml

<?xml version="1.0" encoding="UTF-8"?>

这是我的财产

spring.datasource.username=test
spring.datasource.password=test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.datasource.url=jdbc:mysql://localhost:3306/test_avantrip?verifyServerCertificate=false&useSSL=false&requireSSL=false
server.port=8083
spring.profiles.active=@spring.profiles.active@

我收到的唯一信息是：

有什么建议吗

更新

还没有

更新2

我更改了端口，将其从.properties中删除，并将其保留在8080中，没有看到任何更改。此外，这里还有启动spring引导控制台时的消息

尝试删除属性spring.profiles.active=@spring.profiles.active@

将

@RequestMapping（“/”

移动到控制器类，类似于：

@RestController
public class Controls {

    @RequestMapping("/")
    public String home() {
       return "Hello World!";
    }

}

因此，您的主要方法如下所示：

@SpringBootApplication
public class PaisesApplication  {

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

}

---

如果查看控制台日志，您将不会看到路径“/hi”没有被映射，这意味着spring无法找到您的控制器bean

映射路径时，您应该会在中看到如下内容

RequestMappingHandlerMapping : Mapped "{[/hi],methods=[GET]}".

请将rest控制器移动到它自己的类，它可以在同一个文件中，但可以移动到一个新的不同类，如下所示：

package ar.com.paises;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@SpringBootApplication
public class PaisesApplication  {

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

@RestController
class HiController {

  @RequestMapping("/hi")
  String home() {
    return "Hello World!";
  }
}

此外，请确保在部署应用程序时，会显示上一个日志

根据端口调用端点的方式应为：

检查您的端口，并将文本/普通标题添加为响应类型Spring在接收请求时是否记录了任何内容？@mumpitz No，这是not@AlmasAbdrazak端口是正确的我通过控制台验证过，我更新了我的问题，因为我在TEXT_PLAIN_值中添加了响应类型，但它仍然无法识别，可能还有其他原因。您是否检查了spring引导上下文加载是否成功并启动了tomcat服务器？与数据源相关的配置是否有效？

@SpringBootApplication
public class PaisesApplication  {

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

}

RequestMappingHandlerMapping : Mapped "{[/hi],methods=[GET]}".

package ar.com.paises;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@SpringBootApplication
public class PaisesApplication  {

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

@RestController
class HiController {

  @RequestMapping("/hi")
  String home() {
    return "Hello World!";
  }
}
