[英]Exception stacktrace of Reflected method in Java
I am calling a method via reflection , which throws an exception. 我通过反射调用方法,该方法引发异常。
However when I get the stacktrace via 但是当我通过
StackTraceElement[] elements = Thread.currentThread().getStackTrace();
i don't get the entire stack trace upto the reflected method. 我没有整个堆栈跟踪到反射的方法。 It gets the stack trace only uptil my method which implements reflection.
它仅在实现反射的我的方法之前获取堆栈跟踪。
The reflected class is in a different project altogether. 反映的类完全在另一个项目中。
EDIT : Adding code snippet 编辑:添加代码段
Project A 项目A
Class ReflectionImpl {
public void callMethodsviaReflection{
try{
// Reflection code to call the method
}catch(InvocationTargetException iTE){
StringBuilder errorLogBuilder = new StringBuilder();
errorLogBuilder.append(ex.toString());
errorLogBuilder.append("\n");
StackTraceElement[] elements = Thread.currentThread().getStackTrace();
for (int i=0;i<elements.length;i++) {
errorLogBuilder.append((elements[i].toString()));
errorLogBuilder.append("\n");
}
System.out.println(errorLogBuilder.toString());
}
}
}
Project B --> References Project A in Eclipse 项目B- > 在Eclipse中引用项目A
Class ReflectedClass{
List<String> nameList = null;
public void reflectedMethod(){
nameList.add("Hello");
}
}
At the particular point where you are calling: 在您致电的特定时间点:
StackTraceElement[] elements = Thread.currentThread().getStackTrace();
your 'reflective invocation' has already been completed, which is reflected in the call stack you get back from the call. 您的“反射调用”已经完成,这反映在您从调用返回的调用堆栈中。 Sounds more like you want:
听起来更像您想要的:
iTE.getCause().getStackTrace();
Which will give you the call stack up to and including the method that actually threw the exception. 这将使您的调用堆栈达到并包括实际引发异常的方法。
