另一个解决方案(只有35 - 31个字符):

new Exception().printStackTrace();   
new Error().printStackTrace();

如果希望检查进程的当前调用堆栈，可以使用jstack实用程序。

Usage:
    jstack [-l] <pid>
        (to connect to running process)
    jstack -F [-m] [-l] <pid>
        (to connect to a hung process)
    jstack [-m] [-l] <executable> <core>
        (to connect to a core file)
    jstack [-m] [-l] [server_id@]<remote server IP or hostname>
        (to connect to a remote debug server)

Options:
    -F  to force a thread dump. Use when jstack <pid> does not respond (process is hung)
    -m  to print both java and native frames (mixed mode)
    -l  long listing. Prints additional information about locks
    -h or -help to print this help message

在android上，一个更简单的方法是使用这个:

import android.util.Log;
String stackTrace = Log.getStackTraceString(exception); 

要获得所有线程的堆栈跟踪，您可以使用jstack实用程序，JConsole或发送kill -quit信号(在Posix操作系统上)。

然而，如果你想通过编程来实现，你可以尝试使用ThreadMXBean:

ThreadMXBean bean = ManagementFactory.getThreadMXBean();
ThreadInfo[] infos = bean.dumpAllThreads(true, true);

for (ThreadInfo info : infos) {
  StackTraceElement[] elems = info.getStackTrace();
  // Print out elements, etc.
}

如前所述，如果你只想要当前线程的堆栈跟踪，这要容易得多-只需使用thread . currentthread ().getStackTrace();

在Java 9中有一种新的方法:

public static void showTrace() {

  List<StackFrame> frames =
    StackWalker.getInstance( Option.RETAIN_CLASS_REFERENCE )
               .walk( stream  -> stream.collect( Collectors.toList() ) );

  for ( StackFrame stackFrame : frames )
    System.out.println( stackFrame );
}

加:

StackTraceElement[] ste = Thread.currentThread().getStackTrace();

打印堆栈跟踪(JAVA 8+):

Arrays.asList(ste).forEach(System.out::println);

打印堆栈(java7):

StringBuilder sb = new StringBuilder();

for (StackTraceElement st : ste) {
    sb.append(st.toString() + System.lineSeparator());
}
System.out.println(sb);
