Springboot mongodb 연동

docker에 mongodb를 실행

 - mongodb.yml

version: '3.4'

services:
  mongo:
    image: mongo
    restart: always
    ports:
      - 27017:27017
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: root
    volumes:
      - [host_volume_path]:/data/db

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: root

% docker-compose -f mongodb.yml up -d

 

springboot project

 - pom.xml

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

 

 - Images.java

import java.util.HashMap;

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

import lombok.Data;

@Data
@Document(collection = "images")
public class Images {
	@Id
	private String id;
	private String filename;
	private String originfilename;
	private HashMap<Object, HashMap<Object, Object>> metadata;
}

 

Service  구현

@Autowired
private MongoTemplate mongoTemplate;

Images images = new Images();
images.setFilename(uuidFileName);
images.setOriginfilename(fileName);
images.setMetadata(metadata);
mongoTemplate.insert(images);
