工具类：public final class BeanUtil<T extends Serializable> {
private BeanUtil() {
}
/**
* @param source
* @param clazz
* @return
* @throws IllegalAccessException
* @throws InvocationTargetException
* @throws InstantiationException
*/
public static <T> T copyProperties(Object source, Class<T> clazz) {
if (source == null) {
return null;
}
T t = null;
try {
t = clazz.newInstance();
BeanUtils.copyProperties(source, t);
} catch (Exception e) {
log.error("请求失败", e);
}
return t;
}
/**
* @param source
* @param clazz
* @return
* @throws IllegalAccessException
* @throws InvocationTargetException
* @throws InstantiationException
*/
public static <T> List<T> copyProperties(List<?> source, Class<T> clazz) {
if (source == null || source.size() == 0) {
return Collections.emptyList();
}
List<T> res = new ArrayList<>(source.size());
for (Object o : source) {
T t = null;
try {
t = clazz.newInstance();
BeanUtils.copyProperties(o, t);
} catch (Exception e) {
log.error("请求失败", e);
}
res.add(t);
}
return res;
}
}
具体实现：
BeanUtil.copyProperties(record, CourseChapterPeriodPicVO.class);
其中record的被转化的对象 CourseChapterPeriodPicVO是转化成的对象 就是把record转化为CourseChapterPeriodPicVO
BeanUtil.copyProperties(schoolFileInfos, SchoolFileInfoDTO.class); 这是list之间的转
