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

Question

I am using spring framework in my project,
Here is part of my web.xml:
<servlet>
<servlet-name>SpringMvcServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/servlet-context.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMvcServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<filter>
<filter-name>httpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>httpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<error-page>
<error-code>404</error-code>
<location>/system/404.html</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/system/500.html</location>
</error-page>
And configure:
<mvc:resources mapping="/system/**" location="/WEB-INF/pages/system/" />
But I find so many error in my log, some request like this:
POST /index.php
POST /notexists.html
They were not exists in my server, so will call "/system/404.html", but the mvc:resources don't accept POST method, so it will return 500 Error.
How to fix that? or work around?
Thanks

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.
