Shulou(Shulou.com)06/02 Report--

Springboot visits the page when deployed to the test environment always report errors how to solve, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

When visiting the page, thymeleaf template engine is used. When accessing the resource page, the scope is normal on the windows system's own computer, but the error is always reported when deployed to the test environment:

But look at my configuration:

Spring.thymeleaf.prefix=classpath:/templates/spring.thymeleaf.suffix=.htmlspring.thymeleaf.mode=LEGACYHTML5spring.thymeleaf.encoding=UTF-8spring.thymeleaf.content-type=text/htmlspring.thymeleaf.cache=false

Look at my directory structure (you can see that the directory file exists):

Tried n many ways, still the same

Later, after comparison, it was found that the file name of the resource template must be in all lowercase):

After modification and re-deployment, you can find that the page can be accessed normally:

This problem is really disgusting. I tried a lot of configurations, and then I inadvertently thought of changing the name to all lowercase. It was also an accident to solve the problem. I don't know if it was the problem of springboot or the thymeleaf engine.
