不需要代码生成时，即代码生成后注意要在generator　ut方法上加@Ignore注解

3 说明

• 数据源配置需要换成自己的，dsc.dbType = DbType.MYSQL按需切换
• globalConfig.author = “loulvlin”　author需要换成自己的名字（for 注释）
• 如果不想生成xml，只需要注释下面两行代码：

        //　config xml　template and outpath
        cfg.fileOutConfigList = focList
        mpg.cfg = cfg

• 如果不想生成controller service serviceImpl，只需要配置TemplateConfig相应的set方法为""即可，如下

        mpg.template = TemplateConfig().setXml(null)
                .setController("")
                .setService("")
                .setServiceImpl("")

• 配置需要自动生成代码的表和前缀，如配置了前缀，生成的entity名称中不会出现前缀，不配置前缀也可以

        sc.setTablePrefix("sys")
        sc.setInclude("sys_case_dict")

• 自定义service或controller的基类（按需配置）

        sc.superControllerClass = "com.aos.base.controller.BaseController"
        sc.superServiceClass = "com.aos.base.service.BaseService"

• 生成的entity需要在类前加个open keyword，for redis序列化
• 生成的entity 字段类型 LocalDateTime改为 Date(java.util)

@TableName("sys_case_dict")
open class Xxxxxx : Serializable {


    /**
     * 主键（通过自增生成）
     */
    @TableId(value = "id", type = IdType.AUTO)
    var id: Int? = null
    
    /**
     * 创建时间
     */
    var createTime: Date? = null

    /**
     * 修改时间
     */
    var modifyTime: Date? = null
