mysql2dm-spring-boot-starter

介绍

用于基于MySQL的项目适配达梦数据库。

软件架构

基于Druid里提供的AST工具和Filter实现。在数据库连接层拦截, 上层无感知, 可以用mybatis、jpa甚至jdbcTemplate都可以拦截到。

Druid提供的AST开发简单、灵活、并且性能达到生产级别。

安装教程

前提

项目需要使用 druid-spring-boot-starter

是通过DruidDataSourceWrapper类注册Filter的, 如果不想使用druid-spring-boot-starter, 可以模仿DruidDataSourceWrapper自行注册Filter

安装

将本工程install到本地maven仓库后, 再待改造的项目引入pom即可

<dependency>
      <groupId>com.myth</groupId>
      <artifactId>mysql2dm-spring-boot-starter</artifactId>
      <version>1.0.0-SNAPSHOT</version>
</dependency>

使用说明

  1. 工具中会自动判断当前数据库环境是否是达梦数据库, 是的时候才会拦截修改

扩展说明

若发现有新的语法需要适配, 可以在DmSupportVisitor类里添加

计划

  1. 支持PrepareStatement的占位符和参数顺序的同步调整。

修改sql的时候可能会使原有的占位符位置甚至个数发生变化, 因此对应的参数也需要对应的调整

  1. 动态支持未使用druid-spring-boot-starter, 而只使用了druid

只使用了druid的情况也能支持

  1. 尝试支持未使用druid作为数据库连接池的情况

方案:

  1. 增加其他数据库连接池的自动配置类和拦截器类
  2. 研究一下其他拦截点, 更通用的, 可以跟连接池类型也无关的
