带有 Thymeleaf 的 IntelliJ (2018.3) - static 内容的路径上没有自动完成？

Question

Code completion for paths and filenames do NOT seem to work in IntelliJ with Thymeleaf: th:src="@{...}" attributes - eg files in the resources/static/ folder.

I'm using the latest version of IntelliJ Ultimate Edition (2018.3.x as I am typing this) with the latest Spring Boot "2.1.3.RELEASE", along with the latest Thymeleaf packages.

I have only one controller class, and one HTML template. Simple stuff. I can run the app fine and the content shows up.

However, auto completion for static resources is NOT working when typing in the template - for images, css etc. When using the standard HTML src= attribute eg src="../static/images/mylogo.png" code completion works fine. Paths to static content with Thymeleaf th:src="@{...}" tags have no auto completion at all.

Any suggestions or help would be VERY welcome. I've been using IntelliJ Ultimate for many years, and hopefully this is just a setting I am overlooking. Cannot find anything online pointing at this or a solution. I recall (maybe mistakenly) that this worked a couple years back on a project. Tried on 3 systems and the same behavior. Setting? Config? IntelliJ Bug?

Answer 1

1. File -> Other Settings -> Config Plugins -> check thymeleaf.

2. Add dependency in file: porm.xml

3. In HTML,don't forget to add xmlns:th="http://www.thymeleaf.org"
