本文介绍了一种在Java中获取并打印异常堆栈跟踪的方法。通过使用StringWriter和PrintWriter，可以将Throwable对象的堆栈信息捕获为字符串，便于进行错误记录和调试。
public static String getStackTrace(Throwable throwable) {
Writer writer = new StringWriter();
PrintWriter printWriter = new PrintWriter(writer);
throwable.printStackTrace(printWriter);
return writer.toString();
}
Writer writer = new StringWriter();
PrintWriter printWriter = new PrintWriter(writer);
throwable.printStackTrace(printWriter);
return writer.toString();
}
