mybatis 自动生成代码（mybatis generator）

pom.xml 文件配置

引入 mybatis generator

1. <configurationFile>src/main/resources/generatorConfig.xml</configurationFile> 自动生成代码的核心配置文件 generatorConfig.xml 的路径
2. mysql-connector-java 生成哪种数据库的代码，不可省略
3. com.github.oceanc 引入第三方的 jar，能够生成常用的查询语法
4. resources 标签配置是为了将 mybatis 语法 xml 文件 打包进 war 包，缺少 xml 文件代码是无法执行的
5. org.mybatis.generator 自动生成可执行代码的核心 jar，不可缺少
