### 一、前言 ###

本文基于`springboot 2.4.0`整合`MongoDB`，实现简单的`增删改查`。

### 二、docker-compose安装MongoDB和可视化图形工具adminMongo ###

> 温馨小提示：具体配置查看 [https://gitee.com/zhengqingya/docker-compose][https_gitee.com_zhengqingya_docker-compose]

git clone https://gitee.com/zhengqingya/docker-compose.git
    cd docker-compose/Liunx
    # 运行
    docker-compose -f docker-compose-mongodb.yml -p mongodb up -d

访问可视化图形界面：`http://ip地址:1234`  
添加连接，Connection string：`mongodb://admin:123456@ip地址:27017`

创建`test-db`

### 三、SpringBoot整合MongoDB ###

#### 1、`pom.xml`中引入依赖 ####

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

#### 2、`application.yml`中配置 ####

# MongoDB 配置
    spring:
      data:
        mongodb:
          uri: mongodb://admin:123456@192.168.0.88:27017/test-db?authSource=admin # TODO 根据自己的配置修改

#### 3、测试CRUD ####

@Slf4j
    @RestController
    @RequestMapping("")
    public class TestController { 
    
        @Autowired
        private MongoTemplate mongoTemplate;
    
        @PostMapping("add")
        public void add() { 
            log.info("add");
            mongoTemplate.save(User.builder().id(1L).username("admin").nickname("管理员").build());
            mongoTemplate.save(User.builder().id(2L).username("test").nickname("测试员").build());
        }
    
        @DeleteMapping("delete")
        public void delete() { 
            log.info("delete");
            mongoTemplate.remove(User.builder().id(2L).build());
        }
    
        @PutMapping("update")
        public void update() { 
            log.info("update");
            Query query = new Query(Criteria.where("id").is(1L));
            Update update = new Update();
            update.set("username", "admin01");
            update.set("nickname", "管理员01");
            mongoTemplate.upsert(query, update, User.class);
        }
    
        @GetMapping("select")
        public void select() { 
            log.info("select");
            Query query = new Query(Criteria.where("id").is(1L));
            User user = mongoTemplate.findOne(query, User.class);
            log.info(JSONObject.toJSONString(user));
        }
    
    
    }
    
    @Getter
    @Setter
    @Builder
    @NoArgsConstructor
    @AllArgsConstructor
    @Document(collection = "user")
    class User implements Serializable { 
    
        @Id
        private Long id;
    
        private String username;
    
        private String nickname;
    
    }
