tomcat/conf/server.xml 设置 maxPostSize="0"
<Connector port="8761" protocol="HTTP/1.1" con nectionTimeout="20000" redirectPort="8443" max Threads="500" minSpareThreads="20" acceptCount ="400" disableUploadTimeout="true" enableLooku ps="false" maxPostSize="0" />
maxPostSize参数只有当request的Content-Type为“application/x-www-form-urlencoded”时起作用。
