The difference between/and/*:
< Url-pattern >/</url-pattern > does not match to *.jsp, that is: *.jsp does not enter spring's Dispatcherservlet class.
< Url-pattern >/* </url-pattern > matches *.jsp, a Dispatcherservlet class that returns to the spring when the JSP view is returned. The corresponding controller is not found, so the 404 error is reported.

In summary, a little knowledge of URL mapping for Web. XML:
< url-pattern>/</url-pattern> will match a path URL such as/login, and will not match a suffix URL of pattern *.jsp
< url-pattern>/*</url-pattern> matches all URLs: path-type and suffix-type URLs (including/login,*.jsp,*.js and *.html, etc.)

1. First/This is the default path, and the expression: when no matching URLs are found, use this URL to match. 2. In Springmvc, multiple Dispatcherservlet can be configured, such as: Configure multiple Dispatcherservlet with/and/*, first match/* this 3. When the configuration is the same, the Dispathcherservlet is configured to/and/* Difference < a >/: Use/Configure the path, direct access to the JSP, without springdispatcherservlet< two >//: Configure/* path, Cannot access to multi-view JSP when I call url:/user/list on the client and then return to the user.jsp view, when the configuration is/:dispathcherservlet get this request and return the corresponding controller, Then the forward type is forwarded to the user.jsp view by Dispather type, which is the request user.jsp view (/user/user.jsp), at which time Dispather does not intercept/user/ User.jsp, because at this time you configure the default/, the smooth handing over to Modleandview to handle the display. When the configuration is/*:dispathcherservlet to get this request and then return the corresponding controller, and then through the Dispather type through forward forwarding to the user.jsp view, that is, the request user.jsp view (/ user/user.jsp), at this time Dispather has been intercepted/user/user.jsp,dispatcher will take him as a controller to match, no match will be reported 404 error. Conclusion: Try to use this method when configuring the view.
