问答 dubbo实现类继承其他实现类后无法发布

接口

public interface IDubboBaseService<T> {
    <T> T fastInsert(T obj);
}

public interface IDubboDemoService extends IDubboBaseService<Role>{
    String sayHi(String name);
}

实现类

public class DubboBaseServiceImpl<T> extends EntityService<T> implements IDubboBaseService<T> {
    @Override
    public <T> T fastInsert(T obj) {
        return obj;
    }
}

@IocBean(name = "dubboDemoService", args = {"refer:dao"})
public class DubboDemoServiceImpl extends DubboBaseServiceImpl<Role> implements IDubboDemoService {
    private Dao dao;

    public DubboDemoServiceImpl(Dao dao) {
        this.dao = dao;
    }

    @Override
    public String sayHi(String name) {
        return "hi," + name;
    }
}

如果实现类不继承 DubboBaseServiceImpl 可以正确发布提供者服务。一旦继承了就会报一下错误

 <dubbo:service  id="dubboDemoService_Server" interface="com.demo.service.IDubboDemoService" ref="dubboDemoService" timeout="3000"/>

javassist版本问题,不支持jdk8, 更新一下就好了

更新后解决了
