什么是好的压缩库Java？ [英] What's a good compression library for Java?

问题描述

我需要压缩应用程序的网络流量中的部分性能。我认为这意味着我需要远离一些较新的算法，如bzip2，我认为我听说更慢。

I need to compress portions of our application's network traffic for performance. I presume this means I need to stay away from some of the newer algorithms like bzip2, which I think I have heard is slower.

推荐答案

您可以使用 Deflater / Inflater ，它内置到JDK中。还有GZIPInputStream和GZIPOutputStream，但它真的取决于你的确切用途。

You can use Deflater/Inflater which is built into the JDK. There are also GZIPInputStream and GZIPOutputStream, but it really depends on your exact use.

编辑：

阅读进一步的评论，看起来网络流量是HTTP。根据服务器，它可能支持压缩（特别是使用deflate / gzip）。然后问题出现在客户端。如果客户端是浏览器，它可能已经支持它。如果您的客户端是Web服务客户端或 http客户端，请检查该包的文档

Reading further comments it looks like the network taffic is HTTP. Depending on the server, it probably has support for compression (especially with deflate/gzip). The problem then becomes on the client. If the client is a browser it probably already supports it. If your client is a webservices client or an http client check the documentation for that package to see if it is supported.

看起来像jakarta-commons httpclient可能需要您手动进行压缩。要在客户端启用此功能，您需要执行类似于

It looks like jakarta-commons httpclient may require you to manually do the compression. To enable this on the client side you will need to do something like

.addRequestHeader("Accept-Encoding","gzip,deflate");
