When I use the InternalResourceViewResolver for the JSP rendering, I found the spring complains:

No mapping found for HTTP request with URI [WEB-INF/views/xxx.jsp]

I don’t know why. Normally, it certainly uses this resolver, because spring got the prefix and suffix I set. I open the debug logging, and found the log says:

-mvc-servlet forwards to WEB-INF/views/xxx.jsp
-No handler method found

So it goes to find a hander method, rather than renders directly. Why? Why?

At last, I found it’s the servlet-mapping problem. I map the dispatcher servlet to “/*” instead of “/”. Thus all files include *.jsp also go through the dispatcher servlet. Obviously, I never map the jsp URL to any handler method.

url-pattern: /* and /

the difference is :

SRV.11.2 Specification of Mappings

In theWeb 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.

• 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.

The pattern /* will force everything through your servlet.

The pattern / will make your servlet the default servlet for the app, meaning it will pick up as fallback every pattern that doesn’t have another exact match. So that’s it!
