属性拷贝

//hutool包下的BeanUtil copyProperties() 
DTO -> PO 考到的是一个字节码文件所以用.class后缀

//拷贝单个
User user = BeanUtil.copyProperties(userDTO, User.class);

//拷贝数组
BeanUtil.copyToList(users,UserVO.class);

public class BaseContext {  
  
    public static ThreadLocal<Long> threadLocal = new ThreadLocal<>();
  
    public static void setCurrentId(Long id) {  
        threadLocal.set(id);  
    }  
  
    public static Long getCurrentId() {  
        return threadLocal.get();  
    }  
  
    public static void removeCurrentId() {  
        threadLocal.remove();  
    }  
  
}
