配置一下springboot内置tomcat的 KeepAliveTimeout属性即可

package com.pxwl.devicetxtlog.config;

import org.apache.catalina.connector.Connector;
import org.apache.coyote.http11.Http11NioProtocol;
import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.ConfigurableWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.stereotype.Component;

//当Spring容器中没有TomcatEmbeddedServletContainerFactory这个bean时，会把此bean加载进容器
@Component
public class WebServerConfiguration implements WebServerFactoryCustomizer<ConfigurableWebServerFactory> {
    @Override
    public void customize(ConfigurableWebServerFactory factory) {
        //使用工厂类定制tomcat connector
        ((TomcatServletWebServerFactory)factory).addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                Http11NioProtocol protocol= (Http11NioProtocol) connector.getProtocolHandler();
                //设置15秒无响应则断开keepalive
                protocol.setKeepAliveTimeout(15000);
                //设置最大n次请求后则断开keepalive, -1表示无穷
                protocol.setMaxKeepAliveRequests(-1);
            }
        });
    }
}
