Record the SSM integrated configuration file

Web configuration during SSM integration:

1. <url-pattern> / </ url-pattern>: will not match * .jsp, ie: * .jsp will not enter Spring's DispatcherServlet class.

2. <url-pattern> / * </ url-pattern>: will match path-type and suffix-type url (including / login, .jsp, .js and * .html, etc.), visit .jsp, and return to jsp view When entering the DispatcherServlet class of spring again, it caused a 404 error because it could not find the corresponding controller.

3. Because springmvc uses the DispatcherServlet class to handle front-end requests, it is configured as <url-pattern> / </ url-pattern> to pass the path-type url to springMVC for processing

   For example, Chinese garbled processing and shiro security authentication processing need to handle all urls, so the configuration is <url-pattern> / * </ url-pattern>
