tomcat 添加gzip压缩

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

       <mime-mapping>

              <extension>conf</extension>

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