Spring-boot: Undertow connection timeout is set incorrectly

[jan-krakora]

Spring Boot version: 2.1.1
Undertow version: 2.0.16 (Spring Boot's managed dependency)

Setting

server
    connection-timeout: whatever

then the autoconfiguration class UndertowWebServerFactoryCustomizer sets this property as socket option

builder.setSocketOption(UndertowOptions.NO_REQUEST_TIMEOUT, (int) connectionTimeout.toMillis())

This is ignored by Undertow since this property is expected to be set in server options. Therefore it should be

builder.setServerOption(UndertowOptions.NO_REQUEST_TIMEOUT, (int) connectionTimeout.toMillis())

see Undertow#start() where is merged a default value for this option with all options set in the builder.

OptionMap serverOptions = OptionMap.builder()
                    .set(UndertowOptions.NO_REQUEST_TIMEOUT, 60 * 1000)
                    .addAll(this.serverOptions)
                    .getMap();

Yes! I just found this as well! Can confirm!

Temporary fix is

    @Bean
    public UndertowServletWebServerFactory undertowServletWebServerFactory() {
        final UndertowServletWebServerFactory factory = new UndertowServletWebServerFactory();

        factory.addBuilderCustomizers(builder -> builder.setServerOption(UndertowOptions.NO_REQUEST_TIMEOUT, /* value here */));

        return factory;
    }

Closing in favour of #15822.

It doesn't seem to work. and my spring-boot version is 1.5.4,and my code is

    final int connectTimeOut=5000;
    @Bean
    public EmbeddedServletContainerFactory undertow() {
        UndertowEmbeddedServletContainerFactory factory = new  UndertowEmbeddedServletContainerFactory();
        factory.addBuilderCustomizers(builder ->
                {
                builder.setSocketOption(UndertowOptions.NO_REQUEST_TIMEOUT,
                        connectTimeOut);
                }
        );
        return factory;
    }

@MarsYoung Spring Boot 1.5 is end of life. Please upgrade.

[MarsYoung]

@philwebb It's hard to update. I have an old project that would take much time to upgrade because there are a lot of old projects using in my project such as spring-boot-starter-jersey, spring-data-influx etc. I have try ,but too much error occurs, finnally I revert all the code. Is there any other solution for this problem based on spring boot 1.5?

@MarsYoung You may be able to fork the code and backport the fix to your own branch but I imagine working though the upgrade pain will ultimately be easier. I'm afraid we can't support the older code indefinitely.
