BeanUtils copyProperties API忽略null和特定属性 [英] BeanUtils copyProperties API to ignore null and specific propertie
问题描述
Spring的 BeanUtils.copyProperties()
提供了在复制bean时忽略特定属性的选项:
Spring's BeanUtils.copyProperties()
provides option to ignore specific properties while copying beans:
public static void copyProperties(Object source,
Object target,
String[] ignoreProperties) throws BeansException
Apache Commons BeanUtils是否提供类似的功能?
Does the Apache Commons BeanUtils provide a similar feature?
使用Spring的<$ c时也可以忽略空值$ c> BeanUtils.copyProperties(),我在Commons BeanUtils中看到这个功能:
Also is it possible to ignore null values while using Spring's BeanUtils.copyProperties()
, I see this feature with Commons BeanUtils:
Date defaultValue = null;
DateConverter converter = new DateConverter(defaultValue);
ConvertUtils.register(converter, Date.class);
我可以用Spring的BeanUtils实现相同的效果吗?
Can I achieve the same with Spring's BeanUtils?
推荐答案
如果要忽略 null
-value,则必须在复制属性之前使用以下代码行:
If you want to ignore null
-value you have to do it with the following line of code before copying properties:
BeanUtilsBean.getInstance().getConvertUtils().register(false, false, 0);
