我如何在Java中获得当前堆栈跟踪,就像在。net中,你可以做environment。stacktrace ?

我找到了Thread.dumpStack(),但这不是我想要的-我想要得到堆栈跟踪,而不是打印出来。

这是一个老帖子,但这是我的解决方案:

Thread.currentThread().dumpStack();

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);

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));
}

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
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();
