spring-boot 开启Gzip解决办法

spring boot 加入gizp

如果采用jar 的方式不是spring boot 项目：只需在配置文件中开启gzip 压缩就可以了

server.tomcat.remote-ip-header=x-forwarded-forserver.tomcat.protocol-header=x-forwarded-protoserver.tomcat.port-header=X-Forwarded-Portserver.use-forward-headers=trueserver.compression.enabled=trueserver.compression.mime-types=application/json,application/xml,text/html,text/xml,text/plain

但是如果要部署到tomcat，需要如下对tomcat 安装目录下的conf/server.xml 作如下修改：

<!--    <Connector port="8080" protocol="HTTP/1.1"               connectionTimeout="20000"               redirectPort="8443" />-->        <!--开启gzip--> <Connector port ="8080" protocol="HTTP/1.1"  maxHttpHeaderSize ="8192" maxThreads ="150"  minSpareThreads ="25" maxSpareThreads ="75" enableLookups ="false" redirectPort ="8443" acceptCount ="100"     connectionTimeout ="20000" disableUploadTimeout ="true" URIEncoding ="utf-8"      compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla, traviata"        compressableMimeType="application/json,application/xml,text/html,text/xml,text/plain"/>

原理：

spring 以jar 的方式发布是采用内置的tomcat运行的，内部进行一系列的TomcatConnectorCustomizer，EmbededContainerCustomizer 对象的自定义

@Beanpublic 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);                        }                    }            );        }    };}

如果采用自己安装的tomcat部署，就要手动开启这些配置就OK了！！！
