標(biāo)題和上一篇很像,所以特別強(qiáng)調(diào)一下,這個(gè)是Tomcat對象的。

  從TomcatEmbeddedServletContainer的this.tomcat.start()開始,主要是利用LifecycleBase對這一套容器(engine,host,context及wrapper)進(jìn)行啟動(dòng)并發(fā)布諸如configure_start、before_init、after_start的lifecycleEvent事件給相應(yīng)的監(jiān)聽器(如果有的話)。進(jìn)入start,因?yàn)榇藭r(shí)狀態(tài)是LifecycleState.NEW,所以會(huì)執(zhí)行init方法:
