beetlsql3.x版本适配达梦数据库

BeetlSQL介绍

BeetlSQL的目标是提供开发高效 ，维护高效 ，运行高效的数据库访问框架，在一个系统多个库的情况下，提供一致的编写代码方式。支持如下数据平台

• 传统数据库：MySQL(国内兼容MySQL协议的各种大数据库),MariaDB,Oracle,Postgres,DB2,SQL Server，H2,SQLite,Derby，神通，达梦，华为高斯，人大金仓，PolarDB等
• 大数据：HBase，ClickHouse，Cassandar，Hive
• 物联网时序数据库：Machbase，TD-Engine，IotDB
• SQL查询引擎:Drill,Presto，Druid
• 内存数据库:ignite，CouchBase

BeetlSQL 不仅仅是简单的类似MyBatis或者是Hibernate，或者是二者的综合，BeetlSQL远大理想是对标甚至超越Spring Data，是实现数据访问统一的框架，无论是传统数据库，还是大数据，还是查询引擎或者时序库，内存数据库。

BeetlSQL适配

项目适配的gitee地址：https://gitee.com/gy297879328/beetlsql3.x_dm 代码拉下来后，修改application.properties中达梦连接串可以直接跑项目

初始化sql语句

CREATE TABLE "SYS_USER" (
  "id" INT NOT NULL,
  "name" varchar(255) DEFAULT NULL,
  "department_id" int DEFAULT NULL,
  "create_time" date DEFAULT NULL,
  PRIMARY KEY ("id")
) ;


INSERT INTO "SYS_USER" VALUES (1, 'lijz', 1, NULL);
INSERT INTO "SYS_USER" VALUES (2, 'lucy', 1, NULL);
INSERT INTO "SYS_USER" VALUES (3, 'bear', 2, NULL);
INSERT INTO "SYS_USER" VALUES (4, 'mike', 1, NULL);
INSERT INTO "SYS_USER" VALUES (5, 'lisan', 1, NULL);
INSERT INTO "SYS_USER" VALUES (6, 'xb', 1, NULL);
INSERT INTO "SYS_USER" VALUES (7, 'duanwu', 2, NULL);
INSERT INTO "SYS_USER" VALUES (8, 'fenh', 1, NULL);
INSERT INTO "SYS_USER" VALUES (9, 'lj', 2, NULL);
INSERT INTO "SYS_USER" VALUES (10, 'gshen', 1, NULL);
INSERT INTO "SYS_USER" VALUES (11, 'lihui', 1, NULL);

SimpleDataSourceConfig

在com.dameng.beetlsql3_x_dm.DataSource目录下新建连接类

package com.dameng.beetlsql3_x_dm.DataSource;


import com.zaxxer.hikari.HikariDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;

@Configuration
public class SimpleDataSourceConfig {
    @Autowired
    ApplicationContext ctx;

    @Primary
    @Bean(name = "ds1")
    public DataSource datasource(Environment env) {
        HikariDataSource ds = new HikariDataSource();
        ds.setJdbcUrl(env.getProperty("spring.datasource.url"));
        ds.setUsername(env.getProperty("spring.datasource.username"));
        ds.setPassword(env.getProperty("spring.datasource.password"));
        ds.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
        return ds;
    }

}

UserService

package com.dameng.beetlsql3_x_dm.Service;

import org.springframework.beans.factory.annotation.Autowired;

@Service

    public void selectUserList() {
        List<UserInfo> allList = userMapper.all();
        System.out.println(allList);
    }
