springboot操作mongodb

首先需要在springboot项目中引入mongodb的相关java包配置

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.1</version>
        <relativePath/>
    </parent>
 <dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
    </dependency>
</dependencies>

mongodb连接配置

server:
  port: 8088


spring:
  #mongodb配置
  data:
    mongodb:
      uri: mongodb://admin:admin@127.0.0.1:27017/admin

mongodb操作类封装

@Component
public class MongoDBUtil {
 
    @Autowired
    private MongoTemplate mongoTemplate;
 
    /**
     * 保存
     *
     * @param t
     * @param <T>
     * @return
     */
    public <T> T save(T t) {
        return mongoTemplate.save(t);
    }
 
    /**
     * 保存
     *
     * @param t
     * @param collectionName
     * @param <T>
     * @return
     */
    public <T> T save(T t, String collectionName) {
        return mongoTemplate.save(t, collectionName);
    }
 
    /**
     * 查询
     *
     * @param query
     * @param tClass
     * @param <T>
     * @return
     */
    public <T> List<T> find(Query query, Class<T> tClass) {
        return mongoTemplate.find(query, tClass);
    }
 
    /**
     * 查询所有
     *
     * @param tClass
     * @param <T>
     * @return
     */
    public <T> List<T> findAll(Class<T> tClass) {
        return mongoTemplate.findAll(tClass);
    }
 
 
}
