1 环境

1.1 Project JDK 设置为 17

project_jdk

1.2 Gradle JDK 设置为 17

gradle_jdk

1.3 如果需要预览 SQL 语法树，可以安装 IDEA ANTLR v4 插件

antlr4

1.4 如果需要预览 compose 组件，可以安装 IDEA compose 插件

compose

1.5 打包运行 gradle packageDistributionForCurrentOS

2 模块

  • core SQL 处理的核心逻辑
  • desktop 客户端界面

2.1 core 模块包目录

  • generate 脚本生成
  • lang 第三方语法解析
  • model 模型 & 数据结构
  • parser 抽象、简化的解析适配
  • type 数据类型

2.2 core 模块开发

  • 参考 com.enhe.sql.MySQLTransferTest 单元测试
  • 运行测试读取脚本请修改 com.enhe.sql.util.ScriptReader 的读取目录
  • 使用 ANTLR 插件调试：打开左侧工具栏的 ANTLR Preview 窗口，然后鼠标选中 src/test/resources/MySQL/lang/MySqlParser.g4 文件，即可在工具窗口左侧写入 SQL，右侧会展示出他的语法树
  • 主要的解析语法的逻辑在 lang.mysql.visitor 包下
  • 整体运行逻辑是 SQLTransfer 转换器入口 -> SQLParseAdapter 解析适配 -> LangParserVisitor 目标语法解析 -> Model 抽象出模型 -> Generate 生成新的脚本 -> Script 脚本

2.3 desktop 模块开发
