When editing the thymeleaf template engine file, it appears that angle brackets "<>" cannot be entered, and special characters cannot be entered. After inputting, the entire IDEA will freeze or freeze directly. The CPU will take off in a short period of time and generate a large number of errors. log.
When I first encountered this problem on Baidu, many people told me that it was caused by idea's inspection of html files and js code, and that some inspection options needed to be turned off. I couldn't understand it because the inspection of java code is definitely more complicated than js. . Why is the java code page smooth?
Later, I contacted IDEA’s after-sales support staff and provided the error log of my local machine. After analysis, it was caused by the conflict between the VUE plug-in and the thymeleaf plug-in in IDEA2021.3.1 version (other versions are not excluded). This problem will Exposure highlights in thymeleaf file editing, solution:
1. Use webstorm or other front-end editor to edit front-end files
2. Uninstall or disable the VUE plug-in in IDEA
3. Wait for the new version to be fixed
