According to the use and configuration of data permissions in the open source framework

    Ruoyi open source project online documentation ： Introduce | RuoYi     

  If according to the open source project Vue Front and rear separated version ：RuoYi-Vue: be based on SpringBoot,Spring Security,JWT,Vue & Element Before and after the separation of rights management system , It also provides Vue3 Version of  

        In use, ruoyi (RuoYi) When open source projects build their own application systems , The whole process is very simple and efficient , The system runs smoothly , Thanks to the silent efforts of developers behind the ruoyi project , Thank them again ！！

        In use , Functional permissions and button level permissions have been quite mature , It can be used after several direct operations . however , For data isolation , That is, the data permissions of users in different roles , Although the document also describes , There is also a ready-made example , But there is no result business function , It's a little hard to understand , Here I will directly give an example of business functions , Help friends make adjustments according to their business , Complete the use of data permissions , It can meet the needs of the owner .

        First , When establishing the business function database table , Need to add user_id And dept_id, there user_id Indicates who created the record of this table ,dept_id Actually, the founder's Department id, These two fields need to be added to each business function table that requires data permission , For example, my business menu

  Create script sql

DROP TABLE IF EXISTS `print_entrust`;
CREATE TABLE `print_entrust` (
  `id` bigint NOT NULL AUTO_INCREMENT COMMENT 'id',
  `xh` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci DEFAULT NULL COMMENT ' Student number ',
  `entrustedXh` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci DEFAULT '0' COMMENT ' Print terminal ID',
  `printtype` int DEFAULT '0' COMMENT ' Print type ',
  `copies` int DEFAULT '1' COMMENT ' Number of printed copies ',
  `payable` int DEFAULT '0' COMMENT ' To cope with ( branch )',
  `actualpay` int DEFAULT '0' COMMENT ' Paid in ( branch )',
  `create_time` datetime DEFAULT NULL COMMENT ' Print time ',
  `user_id` bigint DEFAULT NULL COMMENT ' founder ',
  `dept_id` bigint DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

After adding the database table , Again web End synchronization database , And automatically generate code

After generating the code file , The structure is as follows ：

Put relevant modules into your own project , There are several areas that need to be modified , as follows ：

1、 stay Controller modular , When adding records , Need to give user_id And dept_id assignment

 

2、 stay xxxx Mapper.xml Add table alias in , Add if according to the frame sql strand

  The table alias here t It will be used in the service layer

3、 stay lmpl Service layer , Add data permission annotation . Be careful ： Use the above t Alias

Here we are , The data permissions of business functions are set . These are the points to pay attention to . that , What if you use it ？

Still here web End , System management -> Role management

  Click More , Display data permissions

There are several options ,

1、 Only my data permission , Explain that you see your own . Generally, this kind of bottom operator ;

2、 division manager , You can only see the data of the personnel in your department ;

3、 Management , Then you can see the data of this department and below ;

The intuition of this permission can be reflected through the department structure tree .

If you feel simple and easy to use , Please give me a compliment , If you feel in doubt , You can leave a message or contact me at any time , To discuss , thank you ！！
