Tomcat初始化与启动流程

初始化入口 startup.bat或者startup.sh

1. org.apache.catalina.startup.Bootstrap#main

public static void main(String args[]) {

        synchronized (daemonLock) {
            if (daemon == null) {
                // Don't set daemon until init() has completed
                Bootstrap bootstrap = new Bootstrap();
                try {
                //初始化
                    bootstrap.init();

            } else if (command.equals("start")) {
                daemon.setAwait(true);
                //加载daemon-就是当前类Boostrap 对象
                daemon.load(args);
                //启动
                daemon.start();

启动入口startup.bat或者startup.sh

1. org.apache.catalina.startup.Bootstrap#main

public static void main(String args[]) {

      ....
                daemon.start();
