Spring Boot Tomcat Configuration, migration from c

Question

I'm migrating a Spring boot application that used to run in the Tomcat container to a Spring Boot application that runs an embedded Tomcat. My old Tomcat configuration has these configurations in the server.xml:

<Connector 
    executor="tomcatThreadPool"
    port="8080"
    protocol="org.apache.coyote.http11.Http11NioProtocol"
    acceptCount="500"
    acceptorThreadCount="2"
    maxThreads="150"
    maxHttpHeaderSize="32768"
    maxHeaderCount="256"
    connectionTimeout="20000"
    maxKeepAliveRequests="-1"
    redirectPort="8443"
    useComet="false"
    socket.appReadBufSize="87380"
    socket.rxBufSize="87380"
    socket.performanceConnectionTime="2"
    socket.performanceLatency="0"
    socket.performanceBandwidth="1"
    server="My server"
    />

I was able to set up most of the properties using a bean

@Bean
public EmbeddedServletContainerFactory embeddedServletContainerFactory() {
    TomcatEmbeddedServletContainerFactory tomcatEmbeddedServletContainerFactory = new TomcatEmbeddedServletContainerFactory();
    tomcatEmbeddedServletContainerFactory.setProtocol("org.apache.coyote.http11.Http11Nio2Protocol");
    tomcatEmbeddedServletContainerFactory.addConnectorCustomizers((TomcatConnectorCustomizer) connector -> {
        AbstractHttp11JsseProtocol<Nio2Channel> handler = (AbstractHttp11JsseProtocol)connector.getProtocolHandler();
        handler.setMaxKeepAliveRequests(-1);
        handler.setAcceptorThreadCount(2);
        handler.setMaxHeaderCount(256);
        connector.setRedirectPort(8443);
    });

    return tomcatEmbeddedServletContainerFactory;
}

And application.xml properties:

server.tomcat.accept-count = 500
server.tomcat.max-threads = 600
server.port = 8080
server.max-http-header-size = 32768
server.connection-timeout = 20000

However I cannot figure out how to set this part

useComet="false"
socket.appReadBufSize="87380"
socket.rxBufSize="87380"
socket.performanceConnectionTime="2"
socket.performanceLatency="0"
socket.performanceBandwidth="1"
server="My server"

Can anyone help me please? Thank you

Answer 1

Try this:

connector.setProperty("useComet", Boolean.toString(false));
connector.setProperty("socket.appReadBufSize", "87380");
connector.setProperty("socket.rxBufSize", "87380");
connector.setProperty("socket.performanceConnectionTime", "2");
connector.setProperty("socket.performanceLatency", "0");
connector.setProperty("socket.performanceBandwidth", "1");
connector.setProperty("server", "My server");

Answer 2

connector.setProperty("socket.appReadBufSize", "87380");
connector.setProperty("socket.rxBufSize", "87380");
connector.setProperty("socket.performanceConnectionTime", "2");
connector.setProperty("socket.performanceLatency", "0");
connector.setProperty("socket.performanceBandwidth", "1");
connector.setProperty("server", "My server");

Worked great. However it's important to check the return value of the connector.setProperty. It's trying to find the right method to call for every property, and returns true if the method was found and the property was set. Unfortunately connector.setProperty("useComet", Boolean.toString(false)); did not work, and returned false.
