Jdk bean转map

       public static Map
   
     beanToMap(Object obj) {
           try {
               Map
    
      map = new HashMap();            BeanInfo beanInfo = Introspector.getBeanInfo(obj.getClass());            PropertyDescriptor[] propertyDescriptors = beanInfo.getPropertyDescriptors();            for (PropertyDescriptor property : propertyDescriptors) {
                   String key = property.getName();                if (key.compareToIgnoreCase("class") == 0) {
                       continue;                }                Method getter = property.getReadMethod();                Transient annotation = getter.getAnnotation(Transient.class);                if (annotation == null) {
                       Object value = getter != null ? getter.invoke(obj) : null;                    map.put(key, value);                }            }            return map;        } catch (IntrospectionException | IllegalAccessException | InvocationTargetException e) {
               throw new IllegalArgumentException(e.getMessage());        }    }}
    
   

apache bean和map互转

import org.apache.commons.beanutils.BeanUtils;private Map beanToMap(Object obj) {
   	try {
   		return BeanUtils.describe(obj);	} catch (IllegalAccessException | InvocationTargetException			| NoSuchMethodException e) {
   		e.printStackTrace();	}	return null;}private List
    mapToBean(List
