10 Practical IntelliJ IDEA Plugins to Boost Development Efficiency

Hello, I’m Wukong. Here I introduce ten IntelliJ IDEA plugins that I find handy and practical.

aiXcoder

aiXcoder

is a Chinese code‑completion tool that predicts code and generates it automatically, reducing manual typing. In practice I combine it with IDEA's postfix completion and configure shortcuts, although many teammates still don’t use these features.

Java Stream Debugger

While Java 8 stream API simplifies code, debugging stream pipelines can be difficult. Java Stream Debugger visualizes each step of a stream, making data flow and bugs easier to spot.

easy_javadoc

easy_javadoc

quickly adds Javadoc comments to Java classes, methods, and fields, supporting custom templates and leveraging IDEA's Live Templates. It also translates identifiers to Chinese, though the quality depends on naming.

Easy Code

Easy Code

generates Java entity, controller, service, dao, and mapper files directly from database tables, enabling rapid scaffolding after connecting to the database.

Restfultoolkit

Restfultoolkit

is a suite for RESTful service development that indexes all request endpoints, allowing quick search, copying of full URLs, and viewing request/response JSON structures via IDEA’s RestServices panel.

Key promoter X

Key promoter X

shows shortcut hints for IDEA actions, helping users remember and use keyboard shortcuts efficiently.

String Manipulation

String Manipulation

provides one‑click case conversion (e.g., camelCase) and supports common string operations such as MD5 and Base64 encoding/decoding.

Translation

Translation

lets you translate selected code or console error messages directly within the IDE.

Git Auto Pull

GitAutoPull

automatically performs a pull before a push, preventing merge conflicts during collaborative development.

.ignore

When committing to github, you can create a .gitignore file to exclude unwanted files, which appear greyed out in the IDE.

These ten plugins can noticeably improve development efficiency, but avoid overloading IDEA with too many extensions as it may cause performance issues.
