1, Project design ideas (steps)
1. Analysis function: what are the functions and application scenarios of different roles
2. Technical analysis: technical selection for different functions
3. Design steps:
Role division - > relationship diagram - > functional module division - > database table design - > Technical Framework Design - > deployment architecture
2, Development environment construction and log
1. Development environment - IDEA, redis\mysql generated by docker image
The database comment field is designed as utf8m64 to store emoj expression
+ IDEA shortcut summary:
Ctrl+shift+r workspace search
Click the class file on the left, and then shift+F6 to rename the class name
Click the left class package, and then alt+insert to create a new class shortcut key
Ctrl+shift+T add unit test
Ctrl+shift+U all uppercase shortcut
Alt+shift + ↑ move code up
Ctrl+Alt+B view implementation class
Search keywords in Ctrl+shift+R workspace
2. log: log4j2 log is recommended (link). Here is the configuration of logback.xml
resources/logback-spring.xml configuration:

</configuration>

3, git common commands (to be added)
git clone https://...
Git check out - B 5-1 (local branch name) 5-1 (remote branch name)
Git check out 6-1

4, Learning methods
1. Recorded code fragment
2. Confirm the development environment, develop objectives and analyze business
3. Write the annotation code first, and then write the code after thinking about the logic
