我们可以在嵌入了springboot的tomcat中启用APR，方法是覆盖org.springframework.boot.web.embedded. tomcat.tomcatServletWebServerFactory，并提供新的 Catalina .connector.连接器和org.apache.coyote.http11.Http11AprProtocol协议。
下面的代码可能有助于完成它。

@Bean
public TomcatServletWebServerFactory servletContainerFactoryProd() {
    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
        @Override
        protected TomcatWebServer getTomcatWebServer(Tomcat tomcat) {
            // to create new directories and files and add them to Context
            return super.getTomcatWebServer(tomcat);
        }
    };
    
    Connector connector = new Connector("org.apache.coyote.http11.Http11AprProtocol");
    Http11AprProtocol protocol = (Http11AprProtocol) connector.getProtocolHandler();
    connector.setProperty("compression", "on");
    connector.setProperty("compressableMimeType", "text/html,text/xml,text/plain,application/json,application/xml");
    // can also enable ssl and provide certificate details
    tomcat.addAdditionalTomcatConnectors(connector);
    return tomcat;
}
