BeanUtils.copyProperties 忽略id

BeanUtils.copyProperties(source, target, getNullPropertyNames(source));这个方法可以复制非null属性。如果你想忽略id属性，可以在源代码中添加一个过滤器，将id属性排除在复制范围之外。可以使用BeanMapper这个类库来实现快速替代BeanUtils.copyProperties方法。BeanMapper利用javassist类库实现了高效的属性复制，避免了BeanUtils在大量调用时的性能问题。另外，需要注意的是，BeanUtils.copyProperties()在属性名相同但类型不同时，不会拷贝该属性值。所以，如果你想忽略id属性，可以在源代码中进行过滤。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
