setAccessible(true)安全檢查不通過 Bean轉Map

	public static Map<String, Object> beanToMap(Object object) throws Exception {
		Map<String, Object> map = new HashMap<String, Object>();

		Class cls = object.getClass();
		Field[] fields = cls.getDeclaredFields();
		for (Field field : fields) {
			field.setAccessible(true);
			map.put(field.getName(), field.get(object));
		}
		return map;
	}
 

上面的程式碼使用了setAccessible(true)公司安全檢查不通過

	public static Map<String, Object> beanToMap(Object obj) {
		if (obj == null) {
			return null;
		}
		Map<String, Object> map = new HashMap<String, Object>();
		try {
			BeanInfo beanInfo = Introspector.getBeanInfo(obj.getClass());
			PropertyDescriptor[] propertyDescriptors = beanInfo.getPropertyDescriptors();
			for (PropertyDescriptor property : propertyDescriptors) {
				String key = property.getName();
				// 過濾class屬性
				if (!key.equals("class")) {
					// 得到property對應的getter方法
					Method getter = property.getReadMethod();
					Object value = getter.invoke(obj);
					map.put(key, value);
				}
			}
		} catch (Exception e) {
			logger.error("transBean2Map Error ", e);
		}
		return map;
	}
 

使用這種方式，安全可靠
