tomcat/conf/server.xml 設定 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引數只有當request的Content-Type為“application/x-www-form-urlencoded”時起作用。
