下面的三个方法都是获取异常的详细信息，或许的异常详细信息以字符串的形式返回，保持栈堆载的风格

方法一：

public static String getExceptionAllinformation(Exception ex){

        String sOut = "";
        sOut += ex.getMessage() + "\r\n";

        StackTraceElement[] trace = ex.getStackTrace();

        for (StackTraceElement s : trace) {

            sOut += "\tat " + s + "\r\n";

        }

        return sOut;

 }

方法二：

 public static String getExceptionAllinformation_01(Exception ex) {

         ByteArrayOutputStream out = new ByteArrayOutputStream();

         PrintStream pout = new PrintStream(out);

         ex.printStackTrace(pout);

         String ret = new String(out.toByteArray());

         pout.close();

         try {

              out.close();

         } catch (Exception e) {

         }

         return ret;

 }

方法三：

    private static String toString_02(Throwable e){

            StringWriter sw = new StringWriter();

            PrintWriter pw = new PrintWriter(sw, true);

            e.printStackTrace(pw);

            pw.flush();

            sw.flush();

            return sw.toString();

    }
