IntelliJ IDEA Tips: SVN Settings, Tomcat Encoding, Compilation Options, Code Templates, and More

1. File modification change visibility

After modifying files in SVN, only the current file shows changes by default; to display parent directories with changed descendants, enable the setting:

File → settings → version control → 勾选show directories with changed descendants

2. Open multiple projects in new windows

3. Solve Tomcat Chinese character garbling

JAVA_TOOL_OPTIONS -Dfile.encoding=UTF-8

4. Multiple import methods cause file path to turn into asterisks

Adjust the settings:

Setting → editor → code style → java → imports

Increase the values for "Class count to..." and "Names count to...".

5. IDEA compilation is very slow

Modify the additional build process VM options:

File → Settings → Compiler → Additional build process VM options

-ea -Xms2048m -Xmx2048m

6. Uniform file encoding in IDEA

Global encoding settings:

File → Other Settings → Default Settings

Editor → File Encodings

Editor → File Encodings

7. UTF‑8 garbling in properties files

Enable "transparent native-to-ascii conversion" in:

file → setting → editor → file encodings

8. Fix Tomcat console garbling in IDEA

Menu: run → Edit Configurations (or the small arrow next to the run button)

Select the Tomcat configuration, then set VM option to UTF‑8:

-Dfile.encoding=UTF-8

9. Generate serialVersionUID with shortcut

After a class implements Serializable, press Alt+Enter to create serialVersionUID.

Navigate to:

setting → inspections → serialization issues → serializable class without ‘serialVersionUID’

10. Configure SVN

11. Configure Maven

12. Configure Tomcat container

13. Globally ignore a directory or file during compilation

14. Set unified compiler and language level

Recommended to use Javac compiler.

15. Set class comment template

/**
 * @Package ${PACKAGE_NAME}
 * @author 侯文远
 * @date ${DATE} ${TIME}
 * @version V1.0
 * @Copyright © 2016-2017 奥琦玮信息科技（北京）有限公司
 */

16. Set method comment template

Create a custom shortcut with the following content (do not start the first line with "*" if it already exists):

@author 侯文远
* @date $date $time

Steps:

Enter /**+enter above the method.

Fill in the relevant information.

At the end, type the custom shortcut, e.g., @aut+tab .

17. IDEA ignore specific files or folders (e.g., .idea, .iml)

18. Language Injection for regex or JSON validation

At a string assignment, press Alt+Enter and select "Inject Language or reference".

19. Add double or single quotes around selected content

Enable "Surround selection on typing quote or brace" in Settings → Editor → General → Smart Keys.

After enabling, select code and press the quote key (Shift+\") to wrap it with double quotes, or use other delimiters like <, {, [.
