Jersey 2中的GZIP编码/ Grizzly

Question

我无法在我的Jersey服务中激活gzip编码。这是我已经试过：

1. 开始了从Getting Started Guide的jersey-quickstart-grizzly2原型。

2. 新增rc.register(org.glassfish.grizzly.http.GZipContentEncoding.class);

   （也试图rc.register(org.glassfish.jersey.message.GZipEncoder.class);）入门mvn exec:java

3. 与curl --compressed -v -o - http://localhost:8080/myapp/myresource

结果测试

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! 

也就是说，尽管请求中有Accept-Encoding: deflate, gzip，但在响应中没有Content-Encoding: gzip。

我在这里错过了什么？

Answer 1

尝试像代码：

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(); 

Answer 2

你必须注册org.glassfish.jersey.server.filter.EncodingFilter为好。这个例子使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); 
} 

这种解决方案的球衣具体的工作不仅与灰熊，但与JDK HTTP服务器也是如此。
