@elmar-chen @diecui1202 感谢回答，private List<Byte> levels是有的，应该是我粘贴问题时弄丢了。
--------
案例我再贴一次吧
-----
@Data
public class SimpleDTO implements Serializable {
private static final long serialVersionUID = 3491623810140922257L;
private Long id;
private List<Byte> levels;
}
----
public interface SimpleProvider {
boolean cxtest(SimpleDTO dto);
}
----
@Component
public class SimpleProviderImpl implements SimpleProvider {
@Override
public boolean cxtest(SimpleDTO dto) {
Long id=dto.getId();
List<Byte> leves=dto.getLevels();
leves.stream().forEach(l-> System.out.println(l));
return true;
}
}
----
消费方（与服务不在同一个应用，消费方和服务都为<dubbo:protocol name="dubbo"）：
SimpleDTO d=new SimpleDTO();
d.setId(23L);
d.setLevels(Arrays.asList((byte)-1,(byte)2));
boolean res= simpleProvider.cxtest(d);
System.out.println(res);
----
