Parametermethodnameresolver parameter Method name resolver in SSM-SPRINGMVC-11:SPRINGMVC

------------I do not have him, but the hand is ripe, humble and foolish, and eager to be hungry-------------

Maybe we've seen one way before. http://localhost:8080/Project name/Background servlet?actionname=login&uname=admin&upwd=123

In this way the servlet is dispatched and the parameters are passed, what am I going to express here? It is? You can stitch the contents back,

So, the parametermethodnameresolver here is to access the method name in this way

Let's talk about the case use step

One, define the parametermethodnameresolver parameter method name Resolver

Second, inject the above defined method name resolver into the bean of the processor you define

Third, in the processor mapper simpleurlhandlermapping the key value of the access, from/* to a specific value, no longer wildcard way

According to this configuration method, your Access URL is HTTP://IP address: The Tomcat port number/project name/Processor mapper with the key value? Actionname= the method name in your processor

Note Check that you have none of my above first.jsp and second.jsp pages, and that Web. XML does not have to be referenced on the last file you wrote
