Rest URL Path is Not Getting Mapped ( Spring Boot )

Question

Consider, following classes for my problem,

Boot Application java class :

package com.abb;

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

@SpringBootApplication(scanBasePackages = {"com.abb.repositories"})
public class ServerApplication {

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

CrudRepository interface ( it just added here because i feel package might cause this issue ) :

package com.abb.repositories;

import org.springframework.data.repository.CrudRepository;
import com.abb.entities.XYZ;

public interface XYZRepository extends CrudRepository<XYZ, Long> { }

Controller Java Class For rest API:

package com.abb.controller;

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.web.bind.annotation.RequestBody; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.ResponseBody; 
import org.springframework.web.bind.annotation.RestController;
import com.abb.repositories.XYZRepository;

@RestController 
@RequestMapping("/abc") 
public class ABCController {

     @Autowired
     private XYZRepository xyzRepository;

     @RequestMapping(value = "/test", method = RequestMethod.POST)
     public @ResponseBody String test(@RequestBody int iValue) {
          return "done" + iValue; 
     }
}

Server Logs :

The problem is that you are limiting spring boots scanner to only scan the repositories package. No other package will be scanned. This means it does not pick up your controllers, which are in "com.abb.controllers" package.

Remove the scanBasePackages attribute, replace the value, or add each individual package that you want scanned.

I recomend this:

@SpringBootApplication

Or this:

@SpringBootApplication(scanBasePackages = {"com.abb"})
