[Spring Boot] 스프링부트 - 몽고디비 연동

 

1. 의존성 추가

// gradle 사용 시 build.gradle
dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
}

// maven 사용 시 pom.xml
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
    </dependency>
</dependencies>

 

 

2. 연결 설정

// application.properties
spring.data.mongodb.uri=mongodb://localhost:27017/mydatabase
spring.data.mongodb.database=mydatabase

// application.yml
spring:
  data:
    mongodb:
      uri: mongodb://localhost:27017/mydatabase
      database: mydatabase

 

3. 엔티티 및 레포지토리 설정

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "users")
public class User {
    @Id
    private String id;
    private String name;
    private int age;

    // Getter, Setter 작성
}

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

public interface UserRepository extends MongoRepository<User, String> {
    User findByName(String name);
}

 

 

4. 서비스, 컨트롤러 구현

import org.springframework.stereotype.Service;
import java.util.List;

@Service
public class UserService {
    private final UserRepository userRepository;

    public UserService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    public List<User> getAllUsers() {
        return userRepository.findAll();
    }

    public User saveUser(User user) {
        return userRepository.save(user);
    }
}

import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@RequestMapping("/users")
public class UserController {
    private final UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @GetMapping
    public List<User> getUsers() {
        return userService.getAllUsers();
    }

    @PostMapping
    public User createUser(@RequestBody User user) {
        return userService.saveUser(user);
    }
}

 

 

5. 실행
