Project Introduction
Back-end technology includes springboot+mybatis+spring security+mysql+redis
Front-end technology includes semanticUI + thymeleaf template engine
Use the tutorial
1. After downloading the project, wait for maven to install the corresponding jar package
2. Download redis by yourself and configure it according to the application.yml requirements under the resource package
3. Install the sql file under the MySQL database execution resource package by yourself
Instructions for use
1. Run the redis server
2. Start the project
3. Access localhost:8080
4. Username: admin Password: admin
Precautions
If an error is reported when exporting information, mysql needs to be set, and the setting method is as follows:
SELECT @@sql_mode; Check whether ONLY_FULL_GROUP_BY is included; if so, execute the following command:
SET GLOBAL sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' ;
SET SESSION sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
After the execution is completed, check it through SELECT @@sql_mode;;
Note: This method is only used for temporary modification. After restarting mysql, the above settings will be invalid.
