Map转换实体类的方法如下：

/**	 * Map转实体类共通方法	 *	 * @param type 实体类class	 * @param map map	 * @return Object	 * @throws Exception     */	public static Object convertMap(Class type, Map map) throws Exception {		BeanInfo beanInfo = Introspector.getBeanInfo(type);		Object obj = type.newInstance();		PropertyDescriptor[] propertyDescriptors =  beanInfo.getPropertyDescriptors();		for (PropertyDescriptor descriptor : propertyDescriptors) {			String propertyName = descriptor.getName();			if (map.containsKey(propertyName)) {				Object value = map.get(propertyName);				descriptor.getWriteMethod().invoke(obj, value);			}		}		return obj;	}

实体类转换Map的方法如下：

/**	 * 实体类转Map共通方法	 *	 * @param bean 实体类	 * @return Map	 * @throws Exception     */	public static Map convertBean(Object bean) throws Exception {		Class type = bean.getClass();		Map returnMap = new HashMap();		BeanInfo beanInfo = Introspector.getBeanInfo(type);		PropertyDescriptor[] propertyDescriptors =  beanInfo.getPropertyDescriptors();		for (PropertyDescriptor descriptor : propertyDescriptors) {			String propertyName = descriptor.getName();			if (!propertyName.equals("class")) {				Method readMethod = descriptor.getReadMethod();				Object result = readMethod.invoke(bean);				if (result != null) {					returnMap.put(propertyName, result);				} else {					returnMap.put(propertyName, "");				}			}		}		return returnMap;	}
