SpringBoot application.yml support for tomcat maxPostSize

It would be convenient if application.yml supported tomcat maxPostSize settings, versus the verbose snippet shown below. (which does enable post params large then 2Mb tomcat default to work).

// stolen from stack overflow
// Set maxPostSize of embedded tomcat server to 10 megabytes 
@Bean
EmbeddedServletContainerCustomizer containerCustomizer() throws Exception {
    return (ConfigurableEmbeddedServletContainer container) -> {
        if (container instanceof TomcatEmbeddedServletContainerFactory) {
            TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory) container;
            tomcat.addConnectorCustomizers(
                (connector) -> {
                    connector.setMaxPostSize(10000000); // 10 MB
                }
            );
        }
    };
}

I wonder if Undertow and Jetty also have equivalent options? It would be nice if we could offer a single property that configured all three.

BTW, if you are just wanting to restrict file uploads you can use multipart.max-file-size=10Mb

In Spring boot application-serverConfig.properties add the following line: server.tomcat.max-http-post-size=5000000

Hey ,

The below is no longer valid

@Bean
EmbeddedServletContainerCustomizer containerCustomizer() throws Exception {
    return (ConfigurableEmbeddedServletContainer container) -> {
        if (container instanceof TomcatEmbeddedServletContainerFactory) {
            TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory) container;
            tomcat.addConnectorCustomizers(
                (connector) -> {
                    connector.setMaxPostSize(10000000); // 10 MB
                }
            );
        }
    };
}

how can in write it as per the new updates?? Please help

@HimanshuChugh2 Judging by https://github.com/spring-projects/spring-boot/issues/18521#issuecomment-668230288, you've already figured this out so I am going to mark your comment as resolved.
