By looking at the front-end html code, there is a syntax error
Although I have commented out the error code
but the use of <! –> can only keep the browser from displaying it, but it can’t keep the thymeleaf template engine from parsing it.
I should have used the thymeleaf comment syntax <! –/* */–> to comment it out
The error message is as follows.
