除了Java应用程序中的异常名称和描述外，还输出调用堆栈

Question

I executing a java application and I see some exception but not call stack. Can I somehow see callstack as well? It would let me better understand what is the problem.

Answer 1

printStackTrace()或getStackTrace()吗？

Answer 2

You can call an Exception object's printStackTrace() method.

Answer 3

try{
//code
}catch(Exception ex){
ex.printStackTrace();
}

You might consider using a logger instead

try{
//code
}catch(Exception ex){
LOG.warn("whatever went wrong", ex);
}
