我有一个实用工具方法，返回一个字符串与stacktrace:

static String getStackTrace(Throwable t) {
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw, true);
    t.printStackTrace(pw);
    pw.flush();
    sw.flush();
    return sw.toString();
}

然后就像这样…

... 
catch (FileNotFoundException e) {
    logger.config(getStackTrace(e));
}

try {
}
catch(Exception e) {
    StackTraceElement[] traceElements = e.getStackTrace();
    //...
}

or

Thread.currentThread().getStackTrace()

也许你可以试试这个:

catch(Exception e)
{
    StringWriter writer = new StringWriter();
    PrintWriter pw = new PrintWriter(writer);
    e.printStackTrace(pw);
    String errorDetail = writer.toString();
}

字符串'errorDetail'包含了堆栈跟踪。

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

托尼，作为对公认答案的评论，给出了似乎是最好的答案，实际上回答了OP的问题:

Arrays.toString(Thread.currentThread().getStackTrace()).replace( ',', '\n' );

．.． OP没有询问如何从异常的堆栈跟踪中获取字符串。尽管我是Apache Commons的忠实粉丝，但当有像上面这么简单的东西时，使用外部库是没有逻辑理由的。

我使用了上面的答案并添加了格式

public final class DebugUtil {

    private static final String SEPARATOR = "\n";

    private DebugUtil() {
    }

    public static String formatStackTrace(StackTraceElement[] stackTrace) {
        StringBuilder buffer = new StringBuilder();
        for (StackTraceElement element : stackTrace) {
            buffer.append(element).append(SEPARATOR);
        }
        return buffer.toString();
    }

    public static String formatCurrentStacktrace() {
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        return formatStackTrace(stackTrace);
    }
}
