第一次使用Java反射，拿属性值

public String resultValue(String objValueTemp, TmpContractInfo tmpContractInfo) throws NoSuchMethodException,
			SecurityException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
		
		Class<TmpContractInfo> clazz = TmpContractInfo.class;
		Method method = clazz.getDeclaredMethod(objValueTemp);
		Object objValue = method.invoke(tmpContractInfo);
		String value = null;
		if (objValue != null && objValue instanceof String) {
			value = (String) objValue;
		}
		return value;
	}
