What’s New in IntelliJ IDEA 2022.3? A Deep Dive into UI, Redis, and Java Enhancements

New IntelliJ IDEA UI

Version 2022.3 introduces an optional new UI that provides a clean, modern look with enhanced functionality. The UI can be previewed and enabled via the Settings toggle.

Universal Settings Sync

The new Settings Sync solution replaces the old IDE Settings Sync and Settings Repository plugins. It synchronizes most user‑configurable settings across all IntelliJ‑based IDEs (except Rider), including platform settings, bundled plugins, and many third‑party plugins.

WSL 2 Project Handling

IntelliJ IDEA Ultimate now launches the backend directly inside WSL 2, providing a smoother experience when working with projects stored in the WSL 2 file system.

Spring Bean Autowiring & OpenAPI Generation

A new action automatically wires Spring Beans in Java files and supports Spring, Micronaut, and Jakarta EE CDI. The OpenAPI workflow is improved, allowing instant generation of OpenAPI definitions from Spring controllers or JAX‑RS resources.

Redis Support

IntelliJ IDEA Ultimate now includes full Redis support. Users can connect to a Redis single‑instance, explore keys in the data viewer, write and execute queries with intelligent code assistance, and benefit from syntax highlighting.

User Experience Improvements

Intent Preview is enabled by default, showing a live preview of code changes when hovering over intention actions.

Search Everywhere algorithm has been fine‑tuned for more accurate result ranking.

Tips of the Day received a redesign with clearer titles, descriptions, and a rating system for feedback.

Bookmarks can now be added from editor tabs, and all open tabs can be bookmarked in a single click.

Code Style Viewer allows reading code in a preferred style without reformatting the file.

Editor Enhancements

Copy, cut, and paste now behave more intuitively when no text is selected; pasting inserts above the current line.

Code Vision for JavaScript/TypeScript shows inheritors, usages, authors, and related problems directly in the editor.

Java Language Updates

New inspections and quick‑fixes protect code from common pitfalls, including a switch‑expression check, redundant array length warnings, and detection of unnecessary collection creation. IntelliJ IDEA 2022.3 also adds full support for Java 19 features such as record patterns and enhanced switch‑expression pattern matching.

Example code snippets:

Collection.parallelStream()

parallel()

Build Tool Changes

Maven2 support is now provided via a dedicated plugin.

An experimental Maven import feature uses the new IntelliJ workspace model API.
