1、编辑文件：jboss\server\default\deploy\jbossweb.sar\server.xml

Xml代码  收藏代码
  1. <Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}" connectionTimeout="20000" redirectPort="8443" />  


修改为（添加compression和compressableMimeType属性，还包括其他的属性compressionMinSize="2048" noCompressionUserAgents="gozilla, traviata）：

Xml代码  收藏代码
  1. <Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}" compression="on" compressableMimeType="text/html,text/xml,text/css,text/javascript, application/x-javascript,application/javascript" connectionTimeout="20000" redirectPort="8443" />
