Spring cannot get the parameters of the applet put request

Just add a filter

<filter>
    <filter-name>HttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HttpPutFormContentFilter
    </filter-class>
</filter>
<filter-mapping>
    <filter-name>HttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
