帮我写个方法,我接收两个未知对象集合,然后把第一个集合BeanUtil.copyProperties(k, copiedObject)复制到第二个集合,最后把第二个集合返回给我

当然可以,这里有一个简单的Java方法示例,假设我们有两个`List<Object>`,其中`Object`类有一个通用的属性可以被复制,比如`public Map<String, Object> properties;`,我们可以用Apache BeanUtils库来进行属性复制。如果你还没有导入BeanUtils,需要先添加依赖:
```java
import org.apache.commons.beanutils.BeanUtils;
import java.util.ArrayList;
import java.util.List;
public class PropertyCopier {
public static <T> List<T> copyProperties(List<T> sourceList, List<T> targetList) throws Exception {
if (sourceList == null || sourceList.isEmpty() || targetList == null) {
throw new IllegalArgumentException("Input lists cannot be null or empty");
}
for (T source : sourceList) {
T target = targetList.get(sourceList.indexOf(source)); // 确保目标列表中有对应的位置
BeanUtils.copyProperties(source, target);
}
return targetList;
}
}
```
这个方法接受两个泛型类型的`List`作为参数,源列表`sourceList`的内容会被复制到目标列表`targetList`中。请注意,这个例子假设对象间的复制是线性的,即源列表中的每个元素都有一个对应的、未被占用的目标位置。
