tomcat添加gzip功能
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
