404 Rest Api with springboot

Question

I already have a couple of days in this and although I know they may see the title of the question repeated, the truth is that I have already tried several solutions that have worked for others but not me. The most likely thing is that it's really very silly and I have not seen it yet but I'm on the edge.

This is my pom.xml

This is my class Application

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
@RestController
public class PaisesApplication  {

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

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

And this is my .properties

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@

The only message I receive is the following

404 not found api

This is the guide that I was following Any suggestions?

Update

@RequestMapping(value="/hi", produces= {MediaType.TEXT_PLAIN_VALUE })
public String home() {
    return "Hello World!";
}

nothing yet

Update 2

I changed the port, removing it from the .properties and leaving it in 8080 I do not see any change. Additionally here are the messages of the spring boot console when I start it

Answer 1

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

Answer 2

Move the @RequestMapping("/") to a controller class, something like :

@RestController
public class Controls {

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

}

So your main method would look like :

@SpringBootApplication
public class PaisesApplication  {

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

}

Answer 3

If you take a look at the console logs you won't see that the path "/hi" is not being mapped, which means spring is not able to find your controller bean.

when a path is mapped you should see something like the following in

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

Please move the rest Controller to its own class, it can be in the same File but move it to a new different class something like the following:

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!";
  }
}

Also, make sure that when you're deploying your application a log as the previous one appear.

The way you should call your endpoint according to your port should be:

http://localhost:8083/hi
