tomcat打开Gzip压缩

compression="on" compressionMinSize="2048" compressableMimeType="application/json;charset=UTF-8"

restTemplate加request.getHeaders().setAcceptEncoding(ContentCodingType.GZIP);

Hi,

I have an apache tomcat 5.5.17. In my server.xml file I have put

[HTML] <Connector port="8080" maxHttpHeaderSize="8192" 
maxThreads="150" minSpareThreads="25" maxSpareThreads="75" 
enableLookups="false" redirectPort="8443" acceptCount="100" 
connectionTimeout="20000" disableUploadTimeout="true" 
compression="on" 
compressionMinSize="2048000" 
noCompressionUserAgents="gozilla, traviata" 
compressableMimeType="text/html,text/xml,text/plain,application/dime" 
/>[/HTML]

But, it always compress the response althought it be less than 1kb. 
What do I have to do for set a compresionminsize?

Thanksss
