本文整理了Java中java.lang.reflect.InvocationTargetException类的一些代码示例，展示了InvocationTargetException类的具体用法。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。InvocationTargetException类的具体详情如下：
包路径：java.lang.reflect.InvocationTargetException
类名称：InvocationTargetException

InvocationTargetException介绍

[英]This class provides a wrapper for an exception thrown by a Method or Constructor invocation.
[中]此类为方法或构造函数调用引发的异常提供包装。

代码示例

public static Exception extractTargetException(InvocationTargetException itex) {
  Throwable target = itex.getTargetException();
  return target instanceof Exception ? (Exception) target : itex;
}

private Object invokeGeneratorMethod(Method generator, Object... args) {

  throw new RuntimeException(e.getCause());
 } catch (Exception e) {
  throwIfUnchecked(e);
  throw new RuntimeException(e);
 }
}

 Throwable cause = e.getCause();
 if (cause != null) {
  throw new RuntimeException(msg + ": " + cause.getMessage(), cause);
 } else {
  throw new RuntimeException(msg + ": " + e.getMessage(), e);
 }
}
