Using VSCode for Java SpringBoot Development: Installation, Configuration, and Tips

Visual Studio Code (VSCode) is a lightweight, open‑source editor that now supports full Java development, including SpringBoot and Lombok, making it a viable alternative to heavyweight IDEs like Eclipse and IntelliJ IDEA.

VSCode Overview : VSCode has over 135K stars on GitHub and runs on multiple platforms. It is faster to launch and more responsive than traditional Java IDEs.

Download and Installation : Download the VSCode zip package from https://code.visualstudio.com/Download , extract it, and run the .exe file. If the system language is Chinese, VSCode will prompt to install the Chinese language pack.

Essential Extensions : Install the "Extension Pack for Java" (which includes six core Java extensions) and the SpringBoot extension pack (three SpringBoot extensions). The Java pack has over 1.39M downloads, indicating wide adoption. Lombok support is built‑in and can be enabled via settings.

Configure Font Size : Adjust the font size in the Appearance settings using the Zoom In or Zoom Out buttons.

Import Maven Project : Install Maven separately, set MAVEN_HOME and update Path (e.g., MAVEN_HOME=D:\developer\env\apache-maven-3.8.6 and Path+=%MAVEN_HOME%\bin ), then clone the mall project from https://github.com/macrozheng/mall and open the folder in VSCode. The project builds faster than in IDEA.

Running and Debugging : Click the run button or use the Spring Boot Dashboard to start the application. Breakpoints work similarly to IDEA, with variable inspection and step‑over/step‑out controls.

Code Navigation : Use Ctrl+T to search by class name, Ctrl+P to search by file name, and Ctrl+Click to jump to definitions. To download source jars for third‑party libraries, run: mvn dependency:sources -DdownloadSources=true -DdownloadJavadocs=true

Key Shortcuts (selected): • View source: Ctrl+Click • Command palette: Ctrl+Shift+P • File search: Ctrl+P • Class search: Ctrl+T • Comment line: Ctrl+/ • Toggle sidebar: Ctrl+B • Global find/replace: Ctrl+Shift+F • Format code: Shift+Alt+F • Refactor: Ctrl+Shift+R

Conclusion : VSCode provides a fast, feature‑rich environment for Java SpringBoot development. While it lacks some IDE‑specific niceties (e.g., colored console logs, automatic source download), its rapid updates and extensive extension marketplace make it a strong contender for Java developers.
