[FIXED] Springboot @RestController is never used

Issue

I'm having trouble getting my spring-boot application working. It's just exposing a single endpoint at the moment. And it's just got a single controller to manage that. Here is the code below.

It builds fine and the tomcat server runs, I get the Whitelabel Error Page.

Full error from chrome console: Failed to load resource: the server responded with a status of 404.

----|java
------|com.domain.myproject.api

----------|RestController.java

----------|SpringApplication.java

RESTController.java

package com.example.myproject.api.Controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class RESTController {

    @GetMapping("/view/{id}")
    public String hello (@PathVariable("id") String id){
        return "return" + id;
    }

}

SpringApplication.java

package com.example.myproject.api.Springboot;

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

@SpringBootApplication
public class CustomsApiApplication {

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

pom-xml

These are the dependencies, which I will get to use.

Thanks!

PS. Also get in the intellij run console. . .

Solution

According to Spring boot documentation 14.2 Locating the main application class, it is recommended that you locate your main application class in a root package above other classes.

The @EnableAutoConfiguration annotation is often placed on your main class, and it implicitly defines a base “search package” for certain items. Using a root package also allows the @ComponentScan annotation to be used without needing to specify a basePackage attribute. Both these annotations are defined within @SpringBootApplication.
