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

突然间，post方式提交不了参数，但是我检查了很久想起来我动过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"，为了取消post数据大小限制，却导致了我提交不了参数，很奇怪。当我取消了maxPostSize="0"，就能够正确提交post的参数了。
