Tomcat源代码解析
详细： http://imtiger.net/blog/2013/10/08/tomcat-source-code-study/1.
Tomcat中的main入口是org.apache.catalina.startup.Bootstrap#main
public void init()throws Exception{
// Set Catalina path
setCatalinaHome();
setCatalinaBase();
initClassLoaders();
Thread.currentThread().setContextClassLoader(catalinaLoader);
SecurityClassLoad.securityClassLoad(catalinaLoader);
// Load our startup class and call its process() method
if (log.isDebugEnabled())
log.debug("Loading startup class");
// 1
Class<?> startupClass =
catalinaLoader.loadClass
("org.apache.catalina.startup.Catalina");
Object startupInstance = startupClass.newInstance();
// Set the shared extensions class loader
if (log.isDebugEnabled())
log.debug("Setting startup class properties");
String methodName = "setParentClassLoader";
Class<?> paramTypes[] = new Class;
paramTypes = Class.forName("java.lang.ClassLoader");
Object paramValues[] = new Object;
paramValues = sharedLoader;
Method method =
startupInstance.getClass().getMethod(methodName, paramTypes);
// 2
method.invoke(startupInstance, paramValues);
// 3
catalinaDaemon = startupInstance;
}
2.
ContainerBase的initInternal方法
protected void initInternal() throws LifecycleException {
BlockingQueue<Runnable> startStopQueue =
new LinkedBlockingQueue<Runnable>();
startStopExecutor = new ThreadPoolExecutor(
getStartStopThreadsInternal(),
getStartStopThreadsInternal(), 10, TimeUnit.SECONDS,
startStopQueue,
new StartStopThreadFactory(getName() + "-startStop-"));
startStopExecutor.allowCoreThreadTimeOut(true);
super.initInternal();
}
