本篇內容主要講解“dubbo接口調用造成的數據插入重復問題怎么解決”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“dubbo接口調用造成的數據插入重復問題怎么解決”吧!

大坑模擬復現

簡單搭建一下dubbo環境 dubbo-service dubbo-service-sdk dubbo-service-web 1、新建module dubbo-service-sdk 定義服務接口

/**
 * @author v_liuwen
 * @date 2019-07-24
 */
public interface AsoService {

    void saveAso(AsoInfoDto asoInfoDto) throws InterruptedException;
}

/**
 * @author v_liuwen
 * @date 2019-07-24
 */
@Data
public class AsoInfoDto implements Serializable {

    private static final long serialVersionUID = 1L;

    private Long asoId;

    private String asoNo;

    private String linkOrderNo;

    private Date createTime;

}

2、新建module dubbo-service 實現sdk的接口 依賴

       <dependency>
            <groupId>top.qrainly</groupId>
            <artifactId>dubbo-service-sdk</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.2.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.13</version>
        </dependency>

/**
 * @author v_liuwen
 * @date 2019-07-24
 */
@Service(version = "1.0", interfaceClass = AsoService.class)
@Component
@Slf4j
public class AsoServiceImpl implements AsoService {

    @Override
    public void saveAso(AsoInfoDto asoInfoDto) throws InterruptedException {
        //模擬阻塞超時
        Thread.sleep(5000);

        log.info("插入售后單信息-->{}", JSONObject.toJSONString(asoInfoDto));
    }
}

3、新建module dubbo-service-web 依賴

        <dependency>
            <groupId>top.qrainly</groupId>
            <artifactId>dubbo-service-sdk</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.2.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.13</version>
        </dependency>

定義業務接口

/**
 * @author v_liuwen
 * @date 2019-07-24
 */
public interface CreateAsoService {

    void saveAso();
}

定義業務實現

/**
 * @author v_liuwen
 * @date 2019-07-24
 */
@Service
@Slf4j
public class CreateAsoServiceImpl implements CreateAsoService {

    @Reference(version = "1.0",check = false)
    private AsoService asoService;
    @Override
    public void saveAso() {
        AsoInfoDto mock = JMockData.mock(AsoInfoDto.class);
        try {
            asoService.saveAso(mock);
        } catch (InterruptedException e) {
            log.error("異常-->{}",e.getMessage());
        }
    }
}

測試類

  @RunWith(SpringRunner.class)
  @SpringBootTest
  public class DubboWebApplicationTests {
  
      @Autowired
      private CreateAsoService createAsoService;
  
      @Test
      public void contextLoads() {
          createAsoService.saveAso();
      }
  
  }

啟動dubbo-service 運行測試方法 控制臺輸出

2019-07-25 21:03:24.655  INFO 6720 --- [:20880-thread-5] t.q.dubboservice.impl.AsoServiceImpl     : 插入售后單信息-->{"asoId":8248,"asoNo":"aQg","createTime":2995060930132,"linkOrderNo":"zDv2"}
2019-07-25 21:03:27.603  INFO 6720 --- [:20880-thread-6] t.q.dubboservice.impl.AsoServiceImpl     : 插入售后單信息-->{"asoId":8248,"asoNo":"aQg","createTime":2995060930132,"linkOrderNo":"zDv2"}
2019-07-25 21:03:30.616  INFO 6720 --- [:20880-thread-7] t.q.dubboservice.impl.AsoServiceImpl     : 插入售后單信息-->{"asoId":8248,"asoNo":"aQg","createTime":2995060930132,"linkOrderNo":"zDv2"}

完美復現問題 剛開始就懷疑是不是重試配置導致的，但是看了一下@Reference的retries默認也是0，也就是說不配置的話默認重試0次，也就是不重試。 那為啥還調了三次。于是嘗試配置了重試次數為-1

@Reference(version = "1.0",retries = -1,check = false)

再次操作 控制臺輸出
