SpringBoot整合MongoDB

一、依赖

            org.springframework.boot
            spring-boot-starter-data-mongodb
        

二、配置

spring:
  data:
    mongodb:
      host: 127.0.0.1
      port: 27017
      database: test

三、实体类

@Data
@Document("user")
@NoArgsConstructor
@AllArgsConstructor
public class User {
 
    @Indexed
    @Field("id")
    private Integer id;
 
    @Field("name")
    private String name;
 
    @Field("age")
    private Integer age;
 
}

四、持久层

public interface UserRepository extends MongoRepository {
 
    /**
     * 通过id查询
     * @param id
     * @return
     */
    Optional findById(Integer id);
}
