Generador de código Mybatis-plus basado en EasyCode, compatible con consultas de paginación de múltiples tablas y condiciones

// Tenga cuidado de no usar AS para definir el alias del campo de alias de la tabla en mapper.xml, no use mayúsculas para la etiqueta where, ew está codificado por mybatisplus, ¡no lo modifique! Use la anotación @Select de mybatis para escribir que la página tiene errores, por ejemplo:

//    @Select(
//            {
    
    
//                    "<script> SELECT ${ew.sqlSelect} FROM t_sys_user_medal  tsum LEFT JOIN t_app_usermlq  tau ON tsum.user_id = tau.id ${ew.customSqlSegment}  </script>"
//            }
//    )分页使用Select注解有bug，数据不能封装到page里面，所以要写成xml格式
