打開conf/server.xml文件可以看到：
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector
port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
<!-- Note : To disable connection timeouts, set connectionTimeout value
to 0 -->
<!-- Note : To use gzip compression you could set the following properties :
compression="on"
compressionMinSize="2048"
noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html,text/xml"
-->
要使用gzip壓縮功能，可以在Connector實例中加上如下屬性:
1) compression="on" 打開壓縮功能
2) compressionMinSize="2048" 啟用壓縮的輸出內容大小，這里面默認為2KB
3) noCompressionUserAgents="gozilla, traviata" 對于以下的瀏覽器，不啟用壓縮&<60;
4) compressableMimeType="text/html,text/xml" 壓縮類型
修改完成后
<Connector
port="8080" 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" />
即在Connector里面增加紅色部分即可。
