Foreword

Although mybatis already have code generation, but for SpringBoot projects generated or needs to be changed, but did not have a logical layer and control layer. But these things can not escape, so I for a single table, made a code generator.

mybatis-dsc-generator

根据完善的数据库表结构，一键生成dao.java,mapper.xml,service.java,serviceImpl.java,controller.java，完成单表的增删改查、组合条件集合查询，组合条件分页查询。

Data table structure style

TABLE `order` the CREATE ( 
  ` id` BIGINT (20 is) the AUTO_INCREMENT the COMMENT the NOT NULL 'ID', 
  `order_no` VARCHAR (50) the COMMENT the NOT NULL 'Order Number', 
  ` uid` BIGINT (20 is) the COMMENT the NOT NULL 'User ID' , 
  `source` VARCHAR (50) the COMMENT the NOT NULL 'source', 
  ` product_id` BIGINT (20 is) the COMMENT the NOT NULL 'item ID', 
  `product_name` VARCHAR (100) the NOT NULL the COMMENT 'product name', 
  ` unit_price` int ( 10) unsigned NOT NULL COMMENT 'monovalent', 
  `number` int (10) unsigned NOT NULL COMMENT 'number', 
  ` selling_price` int (. 11) the COMMENT the DEFAULT NULL 'selling price', 
  `state` int (10) unsigned the NOT NULL DEFAULT '0' COMMENT '0 waiting for payment, a successful payment, payment fails 2, 3 revocation', 
  `create_time` timestamp the NOT NULL the DEFAULT CURRENT_TIMESTAMP the COMMENT 'Created '
  `update_time` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP COMMENT ' changes over time transactions', 
  a PRIMARY KEY (` id`) 
) = the InnoDB ENGINE the AUTO_INCREMENT the DEFAULT = 2 the CHARSET = utf8mb4 the COMMENT = 'order information';

Notes requires the existence of the table, as required must have a primary key id, cut into bigint, all columns must Notes (Notes facilitates generating java).
