Java的Map和Object之间的相互转换方法
public staic Map<String, Object> objectToMap(Object obj) throws Exception { if(obj == null) return null; Map<String, Object> map = new HashMap<String, Object>(); 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(); Object value = getter!=null ? getter.invoke(obj) : null; map.put(key, value); } return map; } public staic Object mapToObject(Map<String, Object> map, Class<?> beanClass) throws Exception { if (map == null) return null; Object obj = beanClass.newInstance(); BeanInfo beanInfo = Introspector.getBeanInfo(obj.getClass()); PropertyDescriptor[] propertyDescriptors = beanInfo.getPropertyDescriptors(); for (PropertyDescriptor property : propertyDescriptors) { Method setter = property.getWriteMethod(); if (setter != null) { setter.invoke(obj, map.get(property.getName())); } } return obj; }
