Cant find interface in spring boot-CodePudding

My server starts up fine but when I use postman to send a request I get a 404 not found. In my server details on console it says "Finished Spring Data repository scanning in 4 ms. Found 0 JPA repository interfaces." I'm just trying to get a simple check to see if a employee is in my MySQL database.

My repository

package com.kingMachine.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import com.kingMachine.entity.Employees;

@Repository
public interface EmployeeRepository extends JpaRepository<Employees, String>{

    @Query("Select S from Employees S where S.id = ?1 and S.password = ?2")
    Employees login(String id, String password);
}

My Controller

package com.kingMachine.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.kingMachine.entity.Employees;
import com.kingMachine.repository.EmployeeRepository;

public class EmployeeController {

    @Autowired
    EmployeeRepository employeeRepository;
    
    //login info finds user by id and password in a query
    @RequestMapping(value="/login",
            produces=MediaType.APPLICATION_JSON_VALUE,
            method=RequestMethod.POST
            )
    public ResponseEntity<Employees>login(@RequestBody Employees employees){
        Employees employeeLogin = employeeRepository.login(employees.getId(), employees.getPassword());
        if(employeeLogin != null) {
            return new ResponseEntity<>(employeeLogin, HttpStatus.OK);
        }else {
            return new ResponseEntity<>(HttpStatus.UNAUTHORIZED);
        }
    }
}

Main Application

package com.kingMachine.login;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages="com.kingMachine")
public class LoginApplication {

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

}

CodePudding user response：

Specify LoginApplication annotations

@SpringBootApplication(scanBasePackages = "com.kingMachine")
@EnableJpaRepositories("com.kingMachine.repository")
@EntityScan("com.kingMachine.entity")
public class LoginApplication {

and add @Controller annotation to EmployeeController so it can be scanned

@Controller
public class EmployeeController {

CodePudding user response：

Since your main class is not in parent package of your repositories. You need to use @EnableJpaRepositories. Or just move you main class into com.kingMachine
