Question

我无法在Jersey服务中激活gzip-encoding。这就是我尝试过的：

开始使用Getting Started Guide中的jersey-quickstart-grizzly2原型。
添加了rc.register(org.glassfish.grizzly.http.GZipContentEncoding.class);

（还试过rc.register(org.glassfish.jersey.message.GZipEncoder.class);）
从mvn exec:java
使用curl --compressed -v -o - http://localhost:8080/myapp/myresource

结果如下：

> GET /myapp/myresource HTTP/1.1
> User-Agent: curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 zlib/1.2.3.4 ...
> Host: localhost:8080
> Accept: */*
> Accept-Encoding: deflate, gzip
> 
< HTTP/1.1 200 OK
< Content-Type: text/plain
< Date: Sun, 03 Nov 2013 08:07:10 GMT
< Content-Length: 7
< 
* Connection #0 to host localhost left intact
* Closing connection #0
Got it!

即使请求中有Accept-Encoding: deflate, gzip，响应中也没有Content-Encoding: gzip。

我在这里缺少什么？

您还必须注册org.glassfish.jersey.server.filter.EncodingFilter。此示例启用deflate和gzip压缩：

import org.glassfish.jersey.message.DeflateEncoder;
import org.glassfish.jersey.message.GZipEncoder;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.filter.EncodingFilter;
...
private void enableCompression(ResourceConfig rc) {
    rc.registerClasses(
            EncodingFilter.class,
            GZipEncoder.class,
            DeflateEncoder.class);
}

此解决方案特定于球衣，不仅适用于Grizzly，也适用于JDK Http服务器。

Answer 2

尝试以下代码：

HttpServer httpServer = GrizzlyHttpServerFactory.createHttpServer(
        BASE_URI, rc, false);

CompressionConfig compressionConfig =
        httpServer.getListener("grizzly").getCompressionConfig();
compressionConfig.setCompressionMode(CompressionConfig.CompressionMode.ON); // the mode
compressionConfig.setCompressionMinSize(1); // the min amount of bytes to compress
compressionConfig.setCompressableMimeTypes("text/plain", "text/html"); // the mime types to compress

httpServer.start();
