[REST][SPRING BOOT] Can't hit the url of the REST API, error 404 is returned in the response JSON

[Robinson Francis]

Dear all,
I have an Controller Class with the following annotations

import java.util.List;
import java.util.UUID;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import lombok.RequiredArgsConstructor;

@RestController
@RequestMapping("projects/v1")
@RequiredArgsConstructor
public class ResourceController {

	
	private final ResourcesService resourcesService;

	
	@CrossOrigin
	@GetMapping("/resources")
	public ResponseEntity<RestResponseWrapper<List<ResourceMinDto>>> getResourceById() {
		return new ResponseEntity<>(new RestResponseWrapper<>(resourcesService.getResources()), HttpStatus.OK);
	}
	
}

I have taken the contents of @RequestMapping("projects/v1") and @GetMapping("/resources") to construct the url and entered it in Postman
http://localhost:8084/resource-service/projects/v1/resources

In response I have gotten is this
{
   "timestamp": 1607569944112,
   "status": 404,
   "error": "Not Found",
   "message": "No message available",
   "path": "/resource-service/projects/v1/resources"
}
These are the entries in the Spring Boot Terminal in INTELLIj IDE after firing the request

Can someone tell me what went wrong? Is there some configurations I need to do in application.yml or something?

[Madan Lal]

I do not see /resource-service in your path. Can you try with http://localhost:8084/projects/v1/resources ?

[Rob Spoor]

I agree. Unlike web applications deployed in a container like Tomcat, JBoss, etc, Spring Boot by default does not use a context path. It can be enabled, but you have to explicitly do this.

[Robinson Francis]

Thanks I removed the context-path from the url in Postman and it worked, thanks.

Robinson, if that answer worked can you please upvote it
