The exception (or rather its cause) tells you exactly what's wrong:

Invalid */ in servlet mapping

In your Java code you try to instantiate the ServletRegistrationBean like this:

ServletRegistrationBean register = 
new ServletRegistrationBean(new ServletContainer(),"*/");

As the exception says */ is not a valid servlet mapping. You probably want /* instead.

From the Java Servlet Specification:

In the Web application deployment descriptor, the following syntax is used to define mappings:

A string beginning with a ‘ / ’ character and ending with a ‘ /* ’ suffix is used for path mapping.

A string beginning with a ‘ *. ’ prefix is used as an extension mapping.

The empty string ("") is a special UR L pattern that exactly maps to the application's context root, i.e., requests of the form http://host:port//. In this case the path info is ’ / ’ and the servlet path and context path is empty string (““).

A string containing only the ’/ ’ character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.

All other strings are used for exact matches only.
