Jersey + GZIP编码

Question

首先，我看了几个例子来说明如何在Jersey中使用GZIP压缩。

不过，我没有看到符合我正在开发的系统要求的东西，因为我使用的是Jersey 1.6，而Jersey从1.9到2.0有很大的变化。除此之外，我看到的所有完整示例都是在Jersey 2.0中。

搜索1.9或更低版本的完整示例，我发现该配置将放在web.xml文件中。

<init-param>
    <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
    <param-value>com.sun.jersey.api.container.filter.GZIPContentEncodingFilter</param-value>
</init-param>
<init-param>
    <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
    <param-value>com.sun.jersey.api.container.filter.GZIPContentEncodingFilter</param-value>
</init-param>

我认为我必须做更多的事情来支持GZIP压缩。注意:我还配置了一个欢迎文件。

编辑: this is my complete web.xml

如何测试servlet？标头中必须有Accept-Encoding:gzip。如果您在浏览器中测试您的web服务，浏览器很可能会将所有内容解压缩并显示给您。试试这个：curl -H Accept-Encoding:gzip -i -u user:pass http://your/web/service
