输出异常到日志

public static void writeException(Exception e) {if (e == null) {log.error("unknown error");return;}try {StackTraceElement[] s = e.getStackTrace();StringBuffer em = new StringBuffer(e.getMessage());if (s != null) {for (int i = 0; i < s.length; i++) {StackTraceElement st = s[i];em.append("\t\t").append(st.toString()).append("\r\n");}}log.error(em.toString());} catch (Exception e1) {e1.printStackTrace();}}

?
