Severe: Error filterstart

Severe: context [] startup failed due to previous errors

 

Cause and solution:

Do not introduce the package: struts2-spring-plugin-2.2.3.jar.

That's simple.

When this jar package exists, No matter you use spring, it will go to the spring-related content to start the spring container. If there is no spring-related content, this error will be reported.
