1.tomcat上的参数优化

//当Spring容器内没有TomcatEmbeddedServletContainerFactory这个bean时，会吧此bean加载进spring容器中
@Component
public class WebServerConfiguration implements WebServerFactoryCustomizer<ConfigurableWebServerFactory> {
    @Override
    public void customize(ConfigurableWebServerFactory configurableWebServerFactory) {
            //使用对应工厂类提供给我们的接口定制化我们的tomcat connector
        ((TomcatServletWebServerFactory)configurableWebServerFactory).addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();

                //定制化keepalivetimeout,设置30秒内没有请求则服务端自动断开keepalive链接
                protocol.setKeepAliveTimeout(30000);
                //当客户端发送超过10000个请求则自动断开keepalive链接
                protocol.setMaxKeepAliveRequests(10000);
            }
        });
    }
}
