BeanUtils.copyProperties三个参数

Bean.copyProperties方法可以通过添加第三个参数来指定要忽略的属性。这个参数可以是一个属性名的字符串，表示要忽略的单个属性，也可以是一个属性名的字符串数组，表示要忽略的多个属性。例如，可以使用以下代码复制属性并忽略id属性：BeanUtils.copyProperties(source, target, "id")。如果要忽略多个属性，可以使用以下代码：BeanUtils.copyProperties(source, target, new String[]{"id", "createDate", "modifyDate"})。这样，在复制属性时就会忽略这些属性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
