尽管我没有特定的方式来加载单个
catalina.properties属性，但我发现它很方便，只需将JarScanner本身重载在Tomcat容器上下文中，如下所示：
答案在Groovy中 （对不起，我很懒）
public static void main(String[] args) throws ServletException, LifecycleException { Tomcat tomcat = new TomcatWithFastJarScanner() tomcat.setPort(8080) StandardContext ctx = (StandardContext) tomcat.addWebapp("/", new File("web").getAbsolutePath()) //declare an alternate location for your "WEB-INF/classes" dir: VirtualDirContext resources = new VirtualDirContext() resources.setExtraResourcePaths("/WEB-INF/classes=" + new File("target/classes")) ctx.setResources(resources) tomcat.start() println "Started server on port 8080" tomcat.getServer().await()}private static class TomcatWithFastJarScanner extends Tomcat { @Override public void start() throws LifecycleException { getServer().findServices().each { service -> service.getContainer().findChildren().each { container -> container.findChildren().each { c -> ((Context) c).setJarScanner(new FastJarScanner()) } } } super.start() }}private static class FastJarScanner extends StandardJarScanner { def jarsToInclude = [ 'spring-web.*' ] @Override public void scan(ServletContext context, ClassLoader classloader, JarScannerCallback callback, Set<String> jarsToSkip) { jarsToSkip = new HashSet<String>(); ((URLClassLoader) classloader.getParent()).getURLs().each { def jar = it.path.find(/[^/]+.jar$/) if(!jar) return for(String inclusionPattern : jarsToInclude) { if(jar.find(inclusionPattern))println "including jar: " + jar else jarsToSkip.add(jar) } } super.scan(context, classloader, callback, jarsToSkip); }}基本思想是，我们正在查看类加载器可以看到的所有jar，并排除了我们不想包含的所有jar。
Tomcat嵌入式可以像这样快速启动！
