Java放气响应 [英] Java deflate response

问题描述

大家好我想为 tomcat 制作一个过滤器来缩小某些 MIME 类型的所有响应.有什么指导方针吗?

Hello all I want to make a filter for tomcat to deflate all responces of certain MIME type. Any guidelines?

...
 String ae = request.getHeader("accept-encoding");
        if (ae != null && ae.indexOf("deflate") != -1) {
            deflate response...?????
        }
chain.doFilter(request, res);

推荐答案

不要在自制的 Filter 中这样做.在服务器级别配置它.例如 Apache Tomcat，只需将 compression="on" 添加到 元素在 /conf/server.xml.只要客户端接受它，它就会响应 GZIP(GZIP 是基于 deflate 的，而且只要支持 deflate，几乎每个客户端都支持它).

Don't do that in a homebrewed Filter. Configure it at server level. In case of for example Apache Tomcat, just add compression="on" to <Connector> element in /conf/server.xml. It will GZIP responses whenever client accepts it (GZIP is based on deflate and practically every client supports it whenever deflate is supported).

<Connector compression="on">

仅此而已.如有必要，您可以通过 compressableMimeType 属性配置 MIME 类型.

That's all. You can if necessary configure mime types by compressableMimeType attribute.
