Spring: not accept POST request under mvc:resources? how to fix that

Question

I am using spring framework in my project,

Here is part of my web.xml:

    SpringMvcServlet

First of all: I think you abuse the ResourceHttpRequestHandler when you try to use it for POST requests. -- And I am not sure that every thing works correct if you made this handler to handle POST requests.

<mvc:resources /> configure an instance of class org.springframework.web.servlet.resource.ResourceHttpRequestHandler. This has the super class WebContentGenerator and this super class has a property Set<String> supportedMethods.

So all what you need to do is:

<property name="supportedMethods">
    <list>
       <value>GET</value>
       <value>HEAD</value>
       <value>POST</value>
    </list>
</property>

Unfortunately this requires that you configure the ResourceHttpRequestHandler by hand instead of using <mvc:resources />

<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
     <property name="urlMap">
         <map>
              <entry key="/system/**" value="myResourceHandler" />
         </map>
     </property>
     <property name="order" value="100000" />       
</bean>

<bean id="myResourceHandler" name="myResourceHandler"
      class="org.springframework.web.servlet.resource.ResourceHttpRequestHandler">
      <property name="locations" value="/WEB-INF/pages/system/" />
      <property name="supportedMethods">
         <list>
            <value>GET</value>
            <value>HEAD</value>
            <value>POST</value>
         </list>
     </property>
     <!-- cacheSeconds: maybe you should set it to zero because of the posts-->
</bean>

I have not proved this configuration, I have just written it down from what the ResourceBeanDefintionParser does.
