- 创建数据表（建议使用PowerDesigner） - 创建数据表（建议使用PowerDesigner）
- 配置对应dao模块的generatorConfig.xml，只需底部追加指定表的代码生成，可生成单表的CRUD功能 - 直接运行对应项目dao模块中的generator.main()，可自动生成单表的CRUD功能和对应的model、example、mapper、service代码
- 生成的model和example均已实现Serializable接口，支持分布式 - 生成的model和example均已实现Serializable接口，支持分布式
- 生成的mapper.xml的selectByExample方法自动包含分页参数offset和limit - 生成的mapper.xml的selectByExample方法自动包含分页参数offset和limit
- 已包含抽象类BaseServiceImpl，只需要继承抽象类并传入泛型参数，即可默认实现mapper接口所有方法，特殊需求直接扩展即可 - 已包含抽象类BaseServiceImpl，只需要继承抽象类并传入泛型参数，即可默认实现mapper接口所有方法，特殊需求直接扩展即可
