tomcat配置压缩JS代码

 <Connector
port="80"               maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" 
   compression="on" 
   compressionMinSize="2048" 
   noCompressionUserAgents="gozilla, traviata" 
   compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,application/vnd.ms-excel,application/pdf,application/json"/>
把server.xml中的压缩打开。
注意传过来要设type
比如设置成json...

注意  compressionMinSize="2048" 意味着当低于2048这个大小时是不会压缩的
