多模块项目spring整合dubbo,服务方正常启动,消费方启动报错解决记录

服务方写法:

<dubbo:application name="babasport-service-product"/>
    <!--2.设置注册中心的地址  zookeeper-->
    <!--  集群式配置:<dubbo:registry address="192.168.200.128:2181,192.168.200.129:2181,192.168.200.130:2181" protocol="zookeeper"/>-->
    <dubbo:registry address="192.168.200.128:2181" protocol="zookeeper"/>
    <!--3.设置启动服务的端口号 (dubbo://协议,也可以使用http协议,在name指定协议) dubbo://192.168.10.1:20880  默认端口号为20880-->
    <dubbo:protocol port="20880" name="dubbo"/>
    <!--4.暴露实现类-->
    <dubbbo:service interface="com.wwr.core.service.TestService" ref="testService"/>

service实现类使用注解注入bean

@Service("testService")
@Transactional
public class TestServiceImpl implements TestService{

    @Autowired
    private TestDao testDao;

    @Override
    public void add(TestDb testDb) {
        testDao.add(testDb);

        //throw new RuntimeException();
    }
}

消费方拿服务:

<dubbo:application name="babasport-console"/>
    <!--2.设置注册中心的地址  zookeeper-->
    <!--  集群式配置:<dubbo:registry address="192.168.200.128:2181,192.168.200.129:2181,192.168.200.130:2181" protocol="zookeeper"/>-->
    <dubbo:registry address="192.168.200.128:2181" protocol="zookeeper"/>
    <!--4.-调用此接口对应的实现类-->
    <dubbo:reference interface="com.wwr.core.service.TestService" id="testService" check="false"/>

此时服务方正常启动,,服务正常注册,,但是消费方启动却报错:

Duplicate spring bean id testService这句话意在说bean重复,,但是我原因也很不明白..但是我试着在服务方实现类将//@Service(“testService”)这个注解注释掉之后,,然后在服务方配置文件手动注入bean,

<!--4.暴露实现类-->
    <bean id="testService" class="com.wwr.core.service.TestServiceImpl"></bean>
    <dubbbo:service interface="com.wwr.core.service.TestService" ref="testService"/>

然后实体类实现序列化:public class TestDb implements Serializable {}
不实现序列化又会报错:
然后启动消费方,成功无报错,,可以获取到testService,,并执行..原因未知,,要是哪位可以告知,不胜感激!
