org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'xxxx' is not present

突然間，post方式提交不了參數，但是我檢查了很久想起來我動過tomcat的server.xml配置

 <Connector executor="tomcatThreadPool"
              port="8888" protocol="org.apache.coyote.http11.Http11NioProtocol"
              connectionTimeout="60000"
               acceptCount="800"
               maxPostSize="0"
               disableUploadTimeout="true"
               URIEncoding="UTF-8"
               enableLookups="false"
               redirectPort="8443" />

添加了，配置maxPostSize="0"，為了取消post數據大小限制，卻導致了我提交不了參數，很奇怪。當我取消了maxPostSize="0"，就能夠正確提交post的參數了。
