blocks|key|162635|text|要启用GZIP压缩，您需要修改嵌入式Tomcat实例的配置。为此，您需要在您的EmbeddedServletContainerCustomizer配置中声明一个Java，然后向它注册一个TomcatConnectorCustomizer。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|162636|例如：|162637|@Bean
public+EmbeddedServletContainerCustomizer+servletContainerCustomizer()+{

++++++++@Override
++++++++public+void+customize(ConfigurableEmbeddedServletContainerFactory+factory)+{

++++++++++++});
++++++++}
++++};
}|code-block|syntax|javascript|162638|有关可用的各种压缩配置选项的更多详细信息，请参阅Tomcat+documentation。|162639|你说你想有选择地启用压缩。根据您的选择标准，上述方法可能就足够了。它使您能够通过请求的用户代理、响应的大小和响应的mime类型来控制压缩。|162640|如果这不能满足您的需求，那么我相信您将不得不在控制器中执行压缩，并返回一个带有gzip内容编码头部的byte[]响应。|162641|entityMap|0|LINK|mutability|MUTABLE|url|http://tomcat.apache.org/tomcat-7.0-doc/config/http.html^0|13|Y|2L|P|0|0|0|O|K|0|0|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@$9|11|A|12|B|C]|$9|13|A|14|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|15|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|16|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|17|8|@]|D|@$9|18|A|19|1|1A]]|E|$]]|$1|O|3|P|5|6|7|1B|8|@]|D|@]|E|$]]|$1|Q|3|R|5|6|7|1C|8|@]|D|@]|E|$]]|$1|S|3|-4|5|6|7|1D|8|@]|D|@]|E|$]]]|T|$U|$5|V|W|X|E|$Y|Z]]]]

To enable GZIP compression, you need to modify the configuration of the embedded Tomcat instance. To do so, you declare a <code>EmbeddedServletContainerCustomizer</code> bean in your Java configuration and then register a <code>TomcatConnectorCustomizer</code> with it.

For example:

<pre><code>@Bean
public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
 return new EmbeddedServletContainerCustomizer() {
 @Override
 public void customize(ConfigurableEmbeddedServletContainerFactory factory) {
 ((TomcatEmbeddedServletContainerFactory) factory).addConnectorCustomizers(new TomcatConnectorCustomizer() {
 @Override
 public void customize(Connector connector) {
 AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
 httpProtocol.setCompression("on");
 httpProtocol.setCompressionMinSize(64);
 }
 });
 }
 };
}
</code></pre>

See the <a href="http://tomcat.apache.org/tomcat-7.0-doc/config/http.html" rel="nofollow">Tomcat documentation</a> for more details on the various compression configuration options that are available.

You say that you want to selectively enable compression. Depending on your selection criteria, then the above approach may be sufficient. It enables you to control compression by the request's user-agent, the response's size, and the response's mime type.

If this doesn't meet your needs then I believe you will have to perform the compression in your controller and return a byte[] response with a gzip content-encoding header.

blocks|key|162674|text|这基本上与@andy-wilkinson提供的解决方案相同，但是在Spring+Boot1.0中，customize(...)方法有一个ConfigurableEmbeddedServletContainer参数。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|162675|值得一提的是，默认情况下，Tomcat只压缩text/html、text/xml和text/plain的内容类型。下面是一个支持application/json压缩的示例：|style|CODE|162676|@Bean

This is basically the same solution as @andy-wilkinson provided, but as of Spring Boot 1.0 the <a href="http://docs.spring.io/spring-boot/docs/1.0.0.RELEASE/api/org/springframework/boot/context/embedded/EmbeddedServletContainerCustomizer.html#customize%28org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer%29">customize(...)</a> method has a <a href="http://docs.spring.io/spring-boot/docs/1.0.0.RELEASE/api/org/springframework/boot/context/embedded/ConfigurableEmbeddedServletContainer.html">ConfigurableEmbeddedServletContainer</a> parameter. 

Another thing that is worth mentioning is that Tomcat only compresses content types of <code>text/html</code>, <code>text/xml</code> and <code>text/plain</code> by default. Below is an example that supports compression of <code>application/json</code> as well:

<pre><code>@Bean
public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
 return new EmbeddedServletContainerCustomizer() {
 @Override
 public void customize(ConfigurableEmbeddedServletContainer servletContainer) {
 ((TomcatEmbeddedServletContainerFactory) servletContainer).addConnectorCustomizers(
 new TomcatConnectorCustomizer() {
 @Override
 public void customize(Connector connector) {
 AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
 httpProtocol.setCompression("on");
 httpProtocol.setCompressionMinSize(256);
 String mimeTypes = httpProtocol.getCompressableMimeTypes();
 String mimeTypesWithJson = mimeTypes + "," + MediaType.APPLICATION_JSON_VALUE;
 httpProtocol.setCompressableMimeTypes(mimeTypesWithJson);
 }
 }
 );
 }
 };
}
</code></pre>

We use Spring Boot/MVC with annotation-based java-config for series of RESTful services and we want to selectively enable HTTP GZIP stream compression on some API responses.
I know I can do this manually in my controller and a <code>byte[] @ResponseBody</code>, however we'd prefer to rely on the Spring MVC infrastructure (filters/etc) and have it automatically do the JSON conversion and compression (i.e. the method returns a POJO).
How can I enable GZIP compression in the ResponseBody or embedded Tomcat instance, and in a way we can selectively compress only some responses?
We don't currently have any XML based configuration.
