java的异常(Exception)信息的详细记录

获取Exception的详细信息

我自己运行的环境:windowsXP、eclipse3.5.1、jdk1.6

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 = ""; StackTraceElement[] trace = ex.getStackTrace(); for (StackTraceElement s : trace) { sOut += " at " + s + " "; } 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(); }
