1. 이전 포스팅

2. mongodb 설치
필자의 경우 mac에서 진행하고 있으므로 아래 글을 참조해 진행했습니다.
https://growingsaja.tistory.com/966
3. 의존성 dependencyies 설정 추가
mongodb 의존성 추가
// vim build.gradle.kts
// ...
dependencies {
// ...
// mongodb
implementation("org.springframework.boot:spring-boot-starter-data-mongodb")
}
// ...
4. application.properties 파일 수정해 연결 DB 설정 입력
H2 database 설정 유지한채로 mongodb쪽 설정 추가
# vim application.properties
# db h2
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:crypto-labs
# mongodb
spring.data.mongodb.uri=mongodb://localhost:27017/test
5. entity 파일 생성 및 소스코드 작성
// vim entities/User.kt
package com.example.practicekopring.entities
import org.springframework.data.annotation.Id
import org.springframework.data.mongodb.core.mapping.Document
@Document(collection = "users")
data class User(
@Id
val id: String? = null,
val username: String,
val email: String
)
6. repository 파일 생성 및 소스코드 작성
// vim repositories/UserRepository.kt
package com.example.practicekopring.repositories
import com.example.practicekopring.entities.User
import org.springframework.data.repository.CrudRepository
interface UserRepository : CrudRepository<User, String> {
fun findByUsername(username: String): User?
}
7. service 파일 생성 및 소스코드 작성
// vim services/UserService.kt
package com.example.practicekopring.services
import com.example.practicekopring.entities.User
import com.example.practicekopring.repositories.UserRepository
import org.springframework.stereotype.Service
@Service
class UserService(private val userRepository: UserRepository) {
fun createUser(username: String, email: String): User {
val user = User(username = username, email = email)
return userRepository.save(user)
}
fun getUserByUsername(username: String): User? {
return userRepository.findByUsername(username)
}
}
8. controller 파일 생성 및 소스코드 작성
// vim controllers/UserController.kt
package com.example.practicekopring.controllers
import com.example.practicekopring.entities.User
import com.example.practicekopring.services.UserService
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.PostMapping
import org.springframework.web.bind.annotation.RequestMapping
import org.springframework.web.bind.annotation.RequestParam
import org.springframework.web.bind.annotation.RestController
import org.springframework.web.bind.annotation.PathVariable
@RestController
@RequestMapping("/api/users")
class UserController(private val userService: UserService) {
@PostMapping("/create")
fun createUser(@RequestParam username: String, @RequestParam email: String): User {
return userService.createUser(username, email)
}
@GetMapping("/{username}")
fun getUserByUsername(@PathVariable username: String): User? {
return userService.getUserByUsername(username)
}
}
9. post method로 데이터 저장 및 조회 시도해서 정상 작동 확인
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'username=testuser01&email=testuser01@gmail.com' http://localhost:8080/api/users/create
curl -X GET -H "Content-Type: application/json" http://localhost:8080/api/users/testuser01
- 전
- 후
10. 여러번 진행해보며 데이터 저장 기능 정상 작동 확인
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'username=testuserSecond&email=testuser02@gmail.com' http://localhost:8080/api/users/create
# {"id":"64f59476f3dc171b96a450aa","username":"testuserSecond","email":"testuser02@gmail.com"}%
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'username=testuserThird&email=testuser03@gmail.com' http://localhost:8080/api/users/create
# {"id":"64f59483f3dc171b96a450ab","username":"testuserThird","email":"testuser03@gmail.com"}%
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'username=testuserHigh&email=testuser99@gmail.com' http://localhost:8080/api/users/create
# {"id":"64f59496f3dc171b96a450ac","username":"testuserHigh","email":"testuser99@gmail.com"}%
curl -X GET -H "Content-Type: application/json" http://localhost:8080/api/users/testuserSecond
# {"id":"64f59476f3dc171b96a450aa","username":"testuserSecond","email":"testuser02@gmail.com"}%
curl -X GET -H "Content-Type: application/json" http://localhost:8080/api/users/testuserThird
# {"id":"64f59483f3dc171b96a450ab","username":"testuserThird","email":"testuser03@gmail.com"}%
curl -X GET -H "Content-Type: application/json" http://localhost:8080/api/users/testuserHigh
# {"id":"64f59496f3dc171b96a450ac","username":"testuserHigh","email":"testuser99@gmail.com"}%
