//打印全部异常堆栈
    public class ExceptionUtils {
    	public static void main(String[] args) {
    		try {
    			int a=1/0;
    		} catch (Exception e) {
    			e.printStackTrace();
    			String fullStackTrace = org.apache.commons.lang.exception.ExceptionUtils.getFullStackTrace(e);
    			System.out.println(fullStackTrace);
     
    		}
    	}
    }

/**
         * <p>A way to get the entire nested stack-trace of an throwable.</p>
         *
         * <p>The result of this method is highly dependent on the JDK version
         * and whether the exceptions override printStackTrace or not.</p>
         *
         * @param throwable  the <code>Throwable</code> to be examined
         * @return the nested stack trace, with the root cause first
         * @since 2.0
         */
        public static String getFullStackTrace(Throwable throwable) {
            StringWriter sw = new StringWriter();
            PrintWriter pw = new PrintWriter(sw, true);
            Throwable[] ts = getThrowables(throwable);
            for (int i = 0; i < ts.length; i++) {
                ts[i].printStackTrace(pw);
                if (isNestedThrowable(ts[i])) {
                    break;
                }
            }
            return sw.getBuffer().toString();
        }

--------------------

//另一种方式
    public static String exception2String(Exception ex){
    		String exceptionMessage = "";
    		if (ex != null) {
    			StringWriter sw = new StringWriter();
    			PrintWriter pw = new PrintWriter(sw);
    			try {
    				ex.printStackTrace(pw);
    				exceptionMessage = sw.toString();
    			} finally {
    				try {
    					sw.close();
    					pw.close();	
    				} catch (Exception e) {
    				}
    			}
    		}
    		return exceptionMessage;
    	}
