#怎样将堆栈追踪信息转换为字符串 ##问题 将Throwable.getStackTrace()的结果转换为一个字符串来来描述堆栈信息的最简单的方法是什么

###最佳答案 可以用下面的方法将异常堆栈信息转换为字符串类型。该类在Apache commons-lang-2.2.jar中可以找到： org.apache.commons.lang.exception.ExceptionUtils.getStackTrace(Throwable)

###答案二 用 Throwable.printStackTrace(PrintWriter pw)可以输出堆栈信息：

StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
t.printStackTrace(pw);
sw.toString(); // stack trace as a string

###答案三

StringWriter sw = new StringWriter();
e.printStackTrace(new PrintWriter(sw));
String exceptionAsString = sw.toString();

###答案四

public String stackTraceToString(Throwable e) {
    StringBuilder sb = new StringBuilder();
    for (StackTraceElement element : e.getStackTrace()) {
        sb.append(element.toString());
        sb.append("\n");
    }
    return sb.toString();
}
