java工具类：对象转map

code如下：

public static Map<String, Object> objectToMap(Object obj){
        if (obj == null) {
            return null;
        }
        Map<String, Object> map = new HashMap<>();
        try {
            BeanInfo beanInfo = Introspector.getBeanInfo(obj.getClass());
            PropertyDescriptor[] propertyDescriptors = beanInfo.getPropertyDescriptors();
            for (PropertyDescriptor property : propertyDescriptors) {
                String key = property.getName();
                // 过滤class属性
                if (!key.equals("class") && !key.equals("pageNo") && !key.equals("pageSize")) {
                    // 得到property对应的getter方法
                    Method getter = property.getReadMethod();
                    Object value = getter.invoke(obj);
                    map.put(key, value);
                }
            }
        } catch (Exception e) {
            System.out.println("transBean2Map Error " + e);
        }
        return map;

    }
