How do I configure this property with Spring Boot and an embedded Tomcat?
提问by smuggledPancakes
Do I configure properties like the connectionTimeout in the application.properties file or is the somewhere else to do it? I can't figure this out from Google.
我是在 application.properties 文件中配置诸如 connectionTimeout 之类的属性还是在其他地方进行配置？我无法从谷歌那里弄清楚这一点。
I found this Spring-Boot example, but it does not include a connectionTimeout property and when I set server.tomcat.connectionTimeout=60000in my application.properties file I get an error.
我找到了这个Spring-Boot 示例，但它不包含 connectionTimeout 属性，当我server.tomcat.connectionTimeout=60000在 application.properties 文件中设置时，出现错误。

Spring Boot 1.4 and later
Spring Boot 1.4 及更高版本
As of Spring Boot 1.4 you can use the property server.connection-timeout. See Spring Boot's common application properties.
从 Spring Boot 1.4 开始，您可以使用该属性server.connection-timeout。请参阅 Spring Boot 的常用应用程序属性。
Spring Boot 1.3 and earlier
Spring Boot 1.3 及更早版本
Provide a customized EmbeddedServletContainerFactorybean:
提供一个定制的EmbeddedServletContainerFactorybean：
@Bean
public EmbeddedServletContainerFactory servletContainerFactory() {
TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
factory.addConnectorCustomizers(connector ->
((AbstractProtocol) connector.getProtocolHandler()).setConnectionTimeout(10000));
// configure some more properties
return factory;
}
If you are not using Java 8 or don't want to use Lambda Expressions, add the TomcatConnectorCustomizerlike this:
如果您不使用 Java 8 或不想使用Lambda 表达式，请添加TomcatConnectorCustomizer如下内容：
factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
@Override
public void customize(Connector connector) {
((AbstractProtocol) connector.getProtocolHandler()).setConnectionTimeout(10000);
}
});
The setConnectionTimeout()method expects the timeout in milliseconds (see connectionTimeoutin Apache Tomcat 8 Configuration Reference).
该setConnectionTimeout()方法需要以毫秒的超时时间（见connectionTimeout在的Apache Tomcat 8配置参考）。

I prefer set of system properties before the server start:
我更喜欢在服务器启动之前设置系统属性：
/**
* Start SpringBoot server
*/
@SpringBootApplication(scanBasePackages= {"com.your.conf.package"})
//@ComponentScan(basePackages = "com.your.conf.package")
public class Application {
public static void main(String[] args) throws Exception {
System.setProperty("server.port","8132"));
System.setProperty("server.tomcat.max-threads","200");
System.setProperty("server.connection-timeout","60000");
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
}

After spring boot 2.x and later, the implement method of the embeding tomcat has been changed.
spring boot 2.x及以后，内嵌tomcat的实现方式发生了变化。
refer to the code below.
请参阅下面的代码。
import org.apache.coyote.http11.AbstractHttp11Protocol;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.context.annotation.Configuration;
import lombok.extern.slf4j.Slf4j;
@Slf4j
@Configuration
public class TomcatCustomizer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {
@Autowired
private ContainerProperties containerProperties;
@Override
public void customize(TomcatServletWebServerFactory factory) {
factory.addConnectorCustomizers(connector -> {
AbstractHttp11Protocol protocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
protocol.setMaxKeepAliveRequests(10);
log.info("####################################################################################");
log.info("#");
log.info("# TomcatCustomizer");
log.info("#");
log.info("# custom maxKeepAliveRequests {}", protocol.getMaxKeepAliveRequests());
log.info("# origin keepalive timeout: {} ms", protocol.getKeepAliveTimeout());
log.info("# keepalive timeout: {} ms", protocol.getKeepAliveTimeout());
log.info("# connection timeout: {} ms", protocol.getConnectionTimeout());
log.info("# max connections: {}", protocol.getMaxConnections());
log.info("#");
log.info(
"####################################################################################");
});
}
}
