[Spring Boot] Spring Boot와 MongoDB 연동하기

 

Spring Boot와 MongoDB를 연동하기에 앞서 MongoDB와 MongoDB Compass를 설치해줍니다!

 

 

의존성 추가

 

implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'

 

 

application.properties

 

spring.jpa.show-sql=true

spring.jpa.hibernate.ddl-auto=update

#spring.jpa.properties.hibernate.format_sql=true

spring.jackson.property-naming-strategy=SNAKE_CASE

spring.mvc.pathmatch.matching-strategy=ant_path_matcher

spring.data.mongodb.host=localhost

spring.data.mongodb.port=27017

spring.data.mongodb.authentication-database=admin

spring.data.mongodb.database=toy

spring.data.mongodb.username=sodas

spring.data.mongodb.password=sodas1234

 

Model 생성

 

아래와 같이 작성하고 서버를 실행시키면 users라는 collection이 생성된다.

import lombok.Data;
import org.springframework.data.mongodb.core.mapping.Document;

@Data
@Document(collection = "users")
public class MongoDBTestModel {
    private String id;
    private String name;
    private int age;
}

 

Repository 생성

 

import org.springframework.data.mongodb.repository.MongoRepository;

public interface MongoDBTestRepository extends MongoRepository<MongoDBTestModel, String> {
    MongoDBTestModel findByName(String name);
}

 

Controller 생성

 

import com.example.toy.service.mongo.MongoDBTestService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@Slf4j
@RestController
@RequestMapping(path = "/mongo")
public class MongoDBTestController {

    @Autowired
    MongoDBTestService mongoDBTestService;

    @GetMapping(value = "/find")
    public String findUserData(@RequestParam String name) {
        return mongoDBTestService.selectUser(name);
    }

    @GetMapping(value = "/save")
    public String saveUserData(@RequestParam String name, @RequestParam int age) {
        log.info("[Controller][Recv] name : {}, age : {}", name, age);
        mongoDBTestService.saveUser(name, age);

        return mongoDBTestService.selectUser(name);
    }
}

 

repository와 controller를 생성한 후 swagger를 통해 API 테스트를 해본다.

 

name과 age를 입력하고 Execute해주면 데이터가 잘 들어가 있는 것을 볼 수 있다!
