java - tomcatembeddedservletcontainerfactory - tomcatservletwebserverfactory spring boot 2




TomcatEmbeddedServletContainerFactory is missing in Spring Boot 2 (2)

I have Spring Boot application version 1.5.x, which uses org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory, I'm trying to migrate it to Spring Boot 2, but the app does not compile, although a have a dependency to org.springframework.boot:spring-boot-starter-tomcat. The compiler issues the error below:

error: package org.springframework.boot.context.embedded.tomcat

In Spring boot 2.0.0.RELEASE you can replace with following code::

@Bean
public ServletWebServerFactory servletContainer() {
    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
        @Override
        protected void postProcessContext(Context context) {
            SecurityConstraint securityConstraint = new SecurityConstraint();
            securityConstraint.setUserConstraint("CONFIDENTIAL");
            SecurityCollection collection = new SecurityCollection();
            collection.addPattern("/*");
            securityConstraint.addCollection(collection);
            context.addConstraint(securityConstraint);
        }
    };
    tomcat.addAdditionalTomcatConnectors(redirectConnector());
    return tomcat;
}

private Connector redirectConnector() {
    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
    connector.setScheme("http");
    connector.setPort(8080);
    connector.setSecure(false);
    connector.setRedirectPort(8443);
    return connector;
}

The class has been removed and replaced by org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory For more info check: Spring-Boot-2.0-Migration-Guide, which says:

In order to support reactive use cases, the embedded containers package structure has been refactored quite extensively. EmbeddedServletContainer has been renamed to WebServer and the org.springframework.boot.context.embedded package has been relocated to org.springframework.boot.web.server. Correspondingly, EmbeddedServletContainerCustomizer has been renamed to WebServerFactoryCustomizer.

For example, if you were customizing the embedded Tomcat container using the TomcatEmbeddedServletContainerFactory callback interface, you should now use TomcatServletWebServerFactory and if you were using an EmbeddedServletContainerCustomizer bean, you should now use a WebServerFactoryCustomizer bean.

I had the problem that I needed to sent bigger request, then the default size allowed:

@Bean
    public TomcatServletWebServerFactory containerFactory() {
        return new TomcatServletWebServerFactory() {
            protected void customizeConnector(Connector connector) {
                int maxSize = 50000000;
                super.customizeConnector(connector);
                connector.setMaxPostSize(maxSize);
                connector.setMaxSavePostSize(maxSize);
                if (connector.getProtocolHandler() instanceof AbstractHttp11Protocol) {

                    ((AbstractHttp11Protocol <?>) connector.getProtocolHandler()).setMaxSwallowSize(maxSize);
                    logger.info("Set MaxSwallowSize "+ maxSize);
                }
            }
        };

    }
