本文整理了Java中java.lang.Thread.getContextClassLoader()方法的一些代码示例，展示了Thread.getContextClassLoader()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Thread.getContextClassLoader()方法的具体详情如下：
包路径：java.lang.Thread
类名称：Thread
方法名：getContextClassLoader

Thread.getContextClassLoader介绍

[英]Returns the context ClassLoader for this Thread. The context ClassLoader is provided by the creator of the thread for use by code running in this thread when loading classes and resources. If not #setContextClassLoader, the default is the ClassLoader context of the parent Thread. The context ClassLoader of the primordial thread is typically set to the class loader used to load the application.

If a security manager is present, and the invoker's class loader is not null and is not the same as or an ancestor of the context class loader, then this method invokes the security manager's SecurityManager#checkPermission(java.security.Permission)method with a RuntimePermission("getClassLoader") permission to verify that retrieval of the context class loader is permitted.
[中]返回此线程的上下文类加载器。上下文类加载器由线程的创建者提供，供在加载类和资源时在此线程中运行的代码使用。如果不是#setContextClassLoader，则默认为父线程的ClassLoader上下文。原始线程的上下文类加载器通常设置为用于加载应用程序的类加载器。
如果存在安全管理器，并且调用方的类加载器不为null，并且与上下文类加载器不相同或不是上下文类加载器的祖先，然后，此方法使用RuntimePermission（“getClassLoader”）权限调用安全管理器的SecurityManager#checkPermission（java.security.Permission）方法，以验证是否允许检索上下文类加载器。
