《基于开源的JAVA mongodb jdbc 驱动 使用教程》

功能价值

1. 与mybaits融合：复用mybatis的功能特性，如:缓存,if动态判断标签等特性
2. 开发更加便捷: 统一dao层,使代码更具维护性，同时操作mongodb 便捷
3. 产品融合能力: 作为底层组件,可以与BI、低代码平台等需要JDBC特性产品融合能力

application-dev.properties 配置

spring.datasource.driverClassName=com.mongo.jdbc.Driver
spring.datasource.url=jdbc:mongo://10.28.55.226:27017/demo_db?isSSL=false
spring.datasource.username=
spring.datasource.password=
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration,org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration
spring.datasource.initial-size=2

JDBC连接串说明

例如:jdbc:mongo://localhost:27017/db_name?isSSL=false
jdbc:mongo://为固定标示，标示为mongodb jdbc 驱动连接串
localhost:27017 :连接的主机和短裤
db_name :为数据库名称
isSSL=false :mongodb连接配置参数，如有多配置参加可以在后面用&keyxx=valuex 追加

Dao层

package com.mongo.jdbc.example.dao;import java.util.Map;import org.apache.ibatis.annotations.Mapper;import com.mongo.jdbc.example.entity.UserEntity;/*** * @author:binggong* @createtime: 2023年12月10日 下午7:18:22 * @version:V.0.1* @tag:  **/
@Mapper
public interface IUserDao {/***  写入数据* @param data* @throws Exception*/public void addData(UserEntity data) throws Exception;/***  查询数据* @param dname* @return* @throws Exception*/public Map getData(String dname) throws Exception;}
