Master IntelliJ IDEA: Code Formatting, UML, Spring Boot Mapping & Debugging
This guide shows how to quickly reformat code without opening settings, generate UML class diagrams, view and test Spring Boot endpoint mappings, navigate debugging execution points, and rename methods using IntelliJ IDEA Ultimate shortcuts, enhancing productivity for Java developers.
01 Code Formatting
Change code style settings without opening the Settings dialog by selecting the relevant code and pressing Alt+Enter (or ⌥Enter) to invoke “Adjust Code Style Settings”.
02 Generate UML Diagram
Reading code is a crucial skill; IntelliJ IDEA Ultimate can help by generating UML diagrams to visualize package components, their members, and dependencies. You can edit, save, print, or share these diagrams.

03 Spring Boot Endpoint Mapping
IntelliJ IDEA Ultimate 2020.1 improves handling of Spring projects. You can view the endpoint mappings of a running application, send HTTP requests to those endpoints, edit requests, and run them directly from the IDE.
04 Debug Jump
When debugging and switching between files, you may lose track of the current execution line. Use “Show Execution Point” to return to that line, or “Run to Cursor” to move the debugger forward to another line.
05 Method Renaming
If you rename a method in IntelliJ IDEA 2020.1, a change icon appears on the left, indicating that you can refactor to update all calls to that method. Press Alt+Enter to apply the suggested change.
