Amazon SQS 消息相关接口测试用例

因项目功能需求，对接了Amazon的SQS消息队列，封装了常用的接口，本文是对部分接口测试用例的简要说明。

1.发送消息

1.1.发送单条消息到标准队列

@Test
public void sendMessage() {
  try {
    // 队列url
    String queueUrl = "https://sqs.cn-northwest-1.amazonaws.com.cn/4203XXXX2685/queue2";

    // 封装消息内容
    JSONObject messageBody = new JSONObject();
    messageBody.put("type", "order");
    messageBody.put("action", "add");
    messageBody.put("userId", "658786756756");
    messageBody.put("skuId", "111");

    // 封装请求参数
    ReqSendMessageBody reqSendMessageBody = new ReqSendMessageBody();
    reqSendMessageBody.setQueueUrl(queueUrl);
    reqSendMessageBody.setMessageBody(messageBody.toJSONString());
    // 发往标准队列的消息可以设置延迟时间，对该条消息有效
    reqSendMessageBody.setDelaySeconds(60);
    /*
     发送消息时，可以添加一些自定义的消息属性。一个完整的消息属性必须包含name、dataType、value，缺一个都会抛出异常
     例如下面添加的属性名称sender（发送人），属性类型String（字符串类型），属性值mgq（自定义值）。
     */
    Map<String, MessageAttributeValue> messageAttributes = new HashMap<>();
    messageAttributes.put("sender", MessageAttributeValue.builder().dataType("String").stringValue("mgq").build());
    reqSendMessageBody.setMessageAttributes(messageAttributes);

    // 发送消息时，可以添加一些消息系统属性。
    Map<MessageSystemAttributeNameForSends, MessageSystemAttributeValue> messageSystemAttributes = new HashMap<>();
    
    /*
     目前只支持属性AWSTraceHeader，AWSTraceHeader属性是AWS 在2016 Re:Invent上推出的X-Ray的保留系统属性。（欲了解X-Ray请自行查阅相关资料）
     若给属性AWSTraceHeader随意传值，则会抛出异常：
     SqsException: The message system attribute 'AWSTraceHeader' is reserved for AWS X-Ray trace header. Value 'what is this?' is invalid.
     */
//      messageSystemAttributes.put(MessageSystemAttributeNameForSends.AWS_TRACE_HEADER,
//        MessageSystemAttributeValue.builder().dataType("String").stringValue("what is this?").build());

    /*
     看源码发现消息系统属性还有一个UNKNOWN_TO_SDK_VERSION，这个“属性”的值其实是null，不是真正的属性，可以理解为它是系统属性枚举的一个“空值”。
     所以不能添加消息系统属性UNKNOWN_TO_SDK_VERSION，否则会抛出异常：
     SqsException: Message system attribute name 'null' is invalid.
     */
//      messageSystemAttributes.put(MessageSystemAttributeNameForSends.UNKNOWN_TO_SDK_VERSION,
//        MessageSystemAttributeValue.builder().dataType("String").stringValue("What's the use of this?").build());

    reqSendMessageBody.setMessageSystemAttributes(messageSystemAttributes);

    // 调用sendMessage接口
    SendMessageResponse response = this.sqsApiSdk.getMessageApi().sendMessage(reqSendMessageBody);

    // 响应信息
    System.out.println("sendMessage response = " + response.toString());
  } catch (SqsException e) {
    e.printStackTrace();
  }
}

控制台打印：
sendMessage response = SendMessageResponse(MD5OfMessageBody=926b9d4682aacf6b756987662b7b7ac9, MD5OfMessageAttributes=593e6a2572f2afcfac33d4a2632701f1, MessageId=38121dcc-57ce-48e0-8f4c-89184ec37591)

1.2.发送单条消息到FIFO队列

@Test
public void sendMessage2fifo() {
  try {
    // 队列url
    String queueUrl = "https://sqs.cn-northwest-1.amazonaws.com.cn/4203XXXX2685/queue1.fifo";

    // 封装消息内容
    JSONObject messageBody = new JSONObject();
    messageBody.put("type", "order");
    messageBody.put("action", "add");
    messageBody.put("userId", "658786756756");
    messageBody.put("skuId", "111");

    // 封装请求参数
    ReqSendMessageBody reqSendMessageBody = new ReqSendMessageBody();
    reqSendMessageBody.setQueueUrl(queueUrl);
    reqSendMessageBody.setMessageBody(messageBody.toJSONString());

    /*
     消息组，可根据实际业务逻辑对消息进行分组。
     若整个队列中的消息都属于同一个消息组，则可以将发往这个队列的消息的MessageGroupId设置为一个统一值，例如：default
     */
    reqSendMessageBody.setMessageGroupId("default");
    /*
     消息重复id，队列会根据这个id判断消息是否重复，fifo队列不会将重复的消息加入队列。
     要么显示的传入MessageDeduplicationId，要么开启队列的“基于内容的重复消息删除”功能，否则会抛出异常:
     SqsException: The queue should either have ContentBasedDeduplication enabled or MessageDeduplicationId provided explicitly

     MessageDeduplicationId的值要根据实际业务逻辑和场景来生成，不能每次都生成一个随机值，否之就无法判断消息是否重复了。
     */
    reqSendMessageBody.setMessageDeduplicationId(messageBody.toJSONString());

    // 调用sendMessage接口
    SendMessageResponse response = this.sqsApiSdk.getMessageApi().sendMessage(reqSendMessageBody);

    // 响应信息
    System.out.println("sendMessage response = " + response.toString());
  } catch (SqsException e) {
    e.printStackTrace();
  }
}

控制台打印：
sendMessage response = SendMessageResponse(MD5OfMessageBody=926b9d4682aacf6b756987662b7b7ac9, MessageId=077215e0-41fa-4144-9aea-8048598b09f1, SequenceNumber=37310312980864223744)

1.3.批量发送消息到标准队列

@Test
public void sendMessageBatch() {
  try {
    // 队列url
    String queueUrl = "https://sqs.cn-northwest-1.amazonaws.com.cn/4203XXXX2685/queue2";

    // 封装参数
    ReqSendMessageBatchBody reqSendMessageBatchBody = new ReqSendMessageBatchBody();
    reqSendMessageBatchBody.setQueueUrl(queueUrl);
    List<ReqSendMessageBody> list = new ArrayList<>();
    for (int i = 0; i < 10; i++) {
      ReqSendMessageBody item = new ReqSendMessageBody();
      /* ！！！
       批量发送消息相较于单条发送，唯一需要注意的就是每条消息都需要有一个id，用于传达结果。
       id的值确保在本次调用中唯一即可。如果能使用业务中的某个字段值更好，便于联系实际业务。
       */
      item.setId(UUID.randomUUID().toString().replace("-", ""));
      item.setMessageBody(String.valueOf(i));
      list.add(item);
    }
    reqSendMessageBatchBody.setSendMessageList(list);

    // 调用sendMessageBatch接口
    RespSendMessageBatchBody response = this.sqsApiSdk.getMessageApi().sendMessageBatch(reqSendMessageBatchBody);

    // 响应信息
    System.out.println("failed num = " + response.getFailedList().size());
    for (BatchResultErrorEntry batchResultErrorEntry : response.getFailedList()) {
      // 此处的id即是请求参数中每条消息的id
      System.out.println("failed id = " + batchResultErrorEntry.id());
      System.out.println("failed code = " + batchResultErrorEntry.code());
      System.out.println("failed message = " + batchResultErrorEntry.message());
      System.out.println("failed senderFault = " + batchResultErrorEntry.senderFault());
    }
    System.out.println("successful num = " + response.getSuccessfulList().size());
    for (SendMessageBatchResultEntry sendMessageBatchResultEntry : response.getSuccessfulList()) {
      // 此处的id即是请求参数中每条消息的id
      System.out.println("successful id = " + sendMessageBatchResultEntry.id());
      System.out.println("successful messageId = " + sendMessageBatchResultEntry.messageId());
    }
  } catch (SqsException e) {
    e.printStackTrace();
  }
}

控制台打印：
failed num = 0
successful num = 10
successful id = 27b5c8691eb44a4ea238c33867dfeb04
successful messageId = 495daa30-3d45-41d7-967a-53b5af067f05
successful id = 066f8c3f91724e7cb51eaf36e7fa1389

successful messageId = 4999a488-0de7-4320-b6b1-46dd9bd38f2a

1.4.批量发送消息到FIFO队列

@Test
public void sendMessageBatch2fifo() {
  try {
    // 队列url
    String queueUrl = "https://sqs.cn-northwest-1.amazonaws.com.cn/4203XXXX2685/queue1.fifo";

    // 封装参数
    ReqSendMessageBatchBody reqSendMessageBatchBody = new ReqSendMessageBatchBody();
    reqSendMessageBatchBody.setQueueUrl(queueUrl);
    List<ReqSendMessageBody> list = new ArrayList<>();
    for (int i = 0; i < 12; i++) {
      ReqSendMessageBody item = new ReqSendMessageBody();
      String iStr = String.valueOf(i);
      /* ！！！
       同样，批量发送时，每条消息都需要一个id来传达结果
       */
      item.setId(iStr);
      item.setMessageBody(iStr);
      item.setMessageGroupId("default");
      item.setMessageDeduplicationId(iStr);
      list.add(item);
    }
    reqSendMessageBatchBody.setSendMessageList(list);

    // 调用sendMessageBatch接口
    RespSendMessageBatchBody response = this.sqsApiSdk.getMessageApi().sendMessageBatch(reqSendMessageBatchBody);

    // 响应信息
    System.out.println("failed size = " + response.getFailedList().size());
    for (BatchResultErrorEntry batchResultErrorEntry : response.getFailedList()) {
      // !!! 此处的id即是请求参数中每条消息的id
      System.out.println("failed id = " + batchResultErrorEntry.id());
      System.out.println("failed code = " + batchResultErrorEntry.code());
      System.out.println("failed message = " + batchResultErrorEntry.message());
      System.out.println("failed senderFault = " + batchResultErrorEntry.senderFault());

      System.out.println("successful messageId = " + sendMessageBatchResultEntry.messageId());
      System.out.println("successful sequenceNumber = " + sendMessageBatchResultEntry.sequenceNumber());
    }
  } catch (SqsException e) {
    e.printStackTrace();
  }
}

控制台打印：

2.检索消息

@Test
public void receiveMessage() {
  try {
    // 队列url
    String queueUrl = "https://sqs.cn-northwest-1.amazonaws.com.cn/4203XXXX2685/queue2";

    // 封装参数
    ReqReceiveMessageBody reqReceiveMessageBody = new ReqReceiveMessageBody();
    reqReceiveMessageBody.setQueueUrl(queueUrl);
    /*
     最大10条，但是不一定返回几条
     当队列中消息数量较少时，甚至一条都不返回（空响应 或 虚假空响应）
     */
    reqReceiveMessageBody.setMaxNumberOfMessages(10);

    /*
     通过设置 waitTimeSeconds参数 启用长轮询（最长20秒），可有效避免空响应和虚假空响应，
     若 waitTimeSeconds值 较小，（响应超时）仍然有可能收到空响应，
     否则至少包含一条有效消息
     */
//      reqReceiveMessageBody.setWaitTimeSeconds(1);

    // 调用receiveMessage接口
    ReceiveMessageResponse response = this.sqsApiSdk.getMessageApi().receiveMessage(reqReceiveMessageBody);

    // 响应信息
    System.out.println("hasMessages = " + response.hasMessages());
    System.out.println("messages size = " + response.messages().size());
    for (Message message : response.messages()) {
      System.out.println("");
      System.out.println("messageId = " + message.messageId());
      System.out.println("body = " + message.body());
      System.out.println("receiptHandle = " + message.receiptHandle());
      // 得到消息，处理完业务逻辑后，可以通过句柄receiptHandle，执行删除消息等操作
    }

  } catch (SqsException e) {
    e.printStackTrace();
  }
}
