java的异常(Exception)信息的详细记录
获取Exception的详细信息
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,保持栈堆的风格
方法一:
public static String getExceptionAllinformation(Exception ex){ String sOut = ""; 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(); }
