tomcat添加gzip功能

gaojinguan

在文件tomcat/conf/server.xml
中添加红色部分的配置即可打开使用压缩传输功能：
 
      <Connector port="8080" address="${jboss.bind.address}"
         maxThreads="250" strategy="ms" maxHttpHeaderSize="8192"
         emptySessionPath="true"
         enableLookups="false" redirectPort="8443" acceptCount="100"
         connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8"
               compression="on"   
         compressionMinSize="2048"   
         noCompressionUserAgents="gozilla, traviata"   
         compressableMimeType="application/java-archive,application/octet-stream,text/vnd.sun.j2me.app-descriptor,application/octet-stream, application/x-msdownload, image/png, image/gif, text/plain" />
 
compression 开关
noCompressionUserAgents 那种浏览器不使用压缩功能
compressionMinSize      启用压缩的输出内容大小，这里面默认为2KB
compressableMimeType    那些文件需要压缩 mimetype
 
在tomcat/webapps/工程/WEB-INF/web.xml中增加下面的配置

              <extension>conf</extension>
              <mime-type>text/plain</mime-type>
