从零开始手写Tomcat的教程12节----StandardContext StandardContext的配置 StandardContext类的构造函数 启动StandardContext类的实例...invoke方法 StandardContextMapper类 对重载的支持 backgroundProcess()方法 小结 ---- ---- StandardContext的配置 ---...- StandardContext类的构造函数 /** * Create a new StandardContext component with the default basic...()); namingResources.setContainer(this); } ---- 启动StandardContext类的实例 /** * Start...(sm.getString("httpContextMapper.container")); context = (StandardContext) container; }
StandardContext 类中的一个属性是 configured 属性，它是一个布尔值，指示一个 StandardContext 实例是否被正确配置。...现在你已经了解了配置 StandardContext 的重要性，让我们更详细地了解 StandardContext 类，从它的构造函数开始。...StandardContext Class's Constructor（StandardContext 类的构造函数） Here is the StandardContext class's constructor...Starting StandardContext（启动 StandardContext） The start method initializes the StandardContext instance...如果生命周期监听器成功执行其配置StandardContext实例的任务，它将把StandardContext的configured属性设置为true。
standardContext = (StandardContext) field.get(applicationContext); // 通过反射从StandardContext获取到filterConfigs...standardContext = (StandardContext) field.get(applicationContext); standardContext.addApplicationEventListener...standardContext = (StandardContext)webappClassLoaderBase.getResources().getContext(); 整合Exploit，代码如下...standardContext = (StandardContext)webappClassLoaderBase.getResources().getContext(); // 通过反射从...standardContext = (StandardContext)webappClassLoaderBase.getResources().getContext(); //
