用番石榴串:

Throwables.getStackTraceAsString(new Throwable())

我真傻，它是Thread.currentThread().getStackTrace();

for (StackTraceElement ste : Thread.currentThread().getStackTrace()) {
    System.out.println(ste + "\n");
}

另一个解决方案(只有35 - 31个字符):

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

用番石榴串:

Throwables.getStackTraceAsString(new Throwable())

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
