我们如何在java中将行号打印到日志中 [英] How can we print line numbers to the log in java

问题描述

如何将行号打印到日志中。假设在向日志输出一些信息时，我还想打印输出在源代码中的行号。正如我们在堆栈跟踪中看到的，它显示发生异常的行号。异常对象上有堆栈跟踪。

How to print line numbers to the log. Say when outputting some information to the log, I also want to print the line number where that output is in the source code. As we can see in the stack trace, it displays the line number where the exception has occurred. Stack trace is available on the exception object.

其他替代方法可能就像打印到日志时手动包含行号一样。还有其他办法吗？

Other alternative could be like manually including the line number when printing to the log. Is there any other way?

From Angsuman Chakraborty:

/** Get the current line number.
 * @return int - Current line number.
 */
public static int getLineNumber() {
    return Thread.currentThread().getStackTrace()[2].getLineNumber();
}
