Solution to content is not allowed in Prolog exception in ehcache Configuration

Hibernate is used in the project and ehcache is used as the second-level cache. After the configuration is completed, the following error always occurs when Tomcat is started:

Severe: exception sending context initialized event to listener instance of class org. springframework. Web. Context. contextloaderlistener

At first, I saw the first error prompt, and thought it was a problem caused by spring or ehcache. After a long time, I found the solution from the content is not allowed in Prolog information:

 

Use NotePad to save the ehcache. xml configuration file as an Anis-encoded file.

 

It took a long time to find the cause and solution to a small problem.
