一、项目目录结构
二、application.yml文件
###服务启动端口号 server: port: 2010 spring: application: name: yjlc-Dm #使用mybatis数据连接 # datasource: # url: jdbc:dm://192.168.200.229:5236/testDB?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8 # username: SYSDBA # password: SYSDBA # driver-class-name: dm.jdbc.driver.DmDriver #使用德鲁伊数据连接池 datasource: name: dm8 type: com.alibaba.druid.pool.DruidDataSource druid: driverClassName: dm.jdbc.driver.DmDriver url: jdbc:dm://192.168.200.229:5236/?testDB&zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8 username: SYSDBA password: SYSDBA mybatis: mapper-locations: classpath*:mapping/**/*.xml
三/启动类
package com.yjlc; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication @MapperScan("com.yjlc.mapper") public class AppDMConformity { public static void main(String[] args) { SpringApplication.run(AppDMConformity.class); } }
四、Service层
package com.yjlc.service; import com.yjlc.entity.UserEntity; import com.yjlc.mapper.ConformityMapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class ConformityService { @Autowired ConformityMapper conformityMapper; @RequestMapping("/test") public void Test(){ System.out.println("进入测试类"); UserEntity userEntity = conformityMapper.selectById(); System.out.println("获取到实体"+userEntity.toString()); } }
五、Entity
package com.yjlc.entity; public class UserEntity { private String id; private String name; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
六、Mapper
package com.yjlc.mapper; import com.yjlc.entity.UserEntity; import org.apache.ibatis.annotations.Mapper; @Mapper public interface ConformityMapper { UserEntity selectById(); }
七、Mapper.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.yjlc.mapper.ConformityMapper"> <select id="selectById" resultType="com.yjlc.entity.UserEntity"> select * from "testDB"."TABLE_1" where "id"=‘2‘; </select> </mapper>
八、报错注意项
(一)mybatis访问达梦数据库时报SSL错误:

(二)解决方案:
在达梦数据库中运行以下代码关闭SSL验证并重启:
sp_set_para_value(2,‘ENABLE_ENCRYPT‘,0);
以上功能亲测有效,如果对以上步骤有所疑问的可以留言讨论。转载请说明出处,本人博客地址:https://www.cnblogs.com/chenyuanbo/
