@SQSListen导致异常，无法正常工作

Question

我有一个非常简单的Spring cloud aws项目。我正在使用Java 11。 这是pom：

配置类：

package com.demo.arf.testsqsboot;

import com.amazonaws.services.sqs.AmazonSQSAsync;
import com.amazonaws.services.sqs.AmazonSQSAsyncClientBuilder;
import org.springframework.beans.factory.annotation.Value;
//import org.springframework.cloud.aws.messaging.core.QueueMessagingTemplate;
import org.springframework.cloud.aws.messaging.config.SimpleMessageListenerContainerFactory;
import org.springframework.cloud.aws.messaging.core.QueueMessagingTemplate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.regions.Regions;
//import com.amazonaws.services.sqs.AmazonSQSAsync;
//import com.amazonaws.services.sqs.AmazonSQSAsyncClientBuilder;

@Configuration
public class SQSConfig {

    @Value("${cloud.aws.region.static}")
    private String region;

    @Value("${cloud.aws.credentials.access-key}")
    private String awsAccessKey;

    @Value("${cloud.aws.credentials.secret-key}")
    private String awsSecretKey;

    @Bean
    public QueueMessagingTemplate queueMessagingTemplate() {
        return new QueueMessagingTemplate(amazonSQSAsync());
    }

    public AmazonSQSAsync amazonSQSAsync() {
        return AmazonSQSAsyncClientBuilder.standard().withRegion(Regions.US_EAST_1)
                .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(awsAccessKey, awsSecretKey)))
                .build();
    }

    @Bean
    public SimpleMessageListenerContainerFactory simpleMessageListenerContainerFactory(AmazonSQSAsync amazonSQS){
        SimpleMessageListenerContainerFactory factory = new SimpleMessageListenerContainerFactory();
        factory.setAmazonSqs(amazonSQS);
        factory.setMaxNumberOfMessages(10);
        return factory;
    }
}

发送/接收消息的控制器类：

package com.demo.arf.testsqsboot.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.aws.messaging.core.QueueMessagingTemplate;
import org.springframework.cloud.aws.messaging.listener.annotation.SqsListener;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class SQSController {
    @Autowired
    private QueueMessagingTemplate queueMessagingTemplate;

    private static final Logger LOG = LoggerFactory.getLogger(SQSController.class);
    @GetMapping("/send-sqs-message")
    public String sendMessage() {
        String sqsEndPoint= "https://sqs.us-east-2.amazonaws.com/1234567879/my_queue";
        queueMessagingTemplate.convertAndSend(sqsEndPoint, MessageBuilder.withPayload("hello from Spring Boot").build());
        return "Hello SQS";
    }

    @SqsListener("my_queue")
    public void getMessage(String message) {
      LOG.info(" *********** Message from SQS Queue - "+message);
    }
}

application.yml：

server:
  port: 9001
cloud:
  aws:
    region:
      static: us-east-1
      auto: false
    credentials:
      access-key: "asdmnasdn"
      secret-key: "sfkjsdjksdkj"
    end-point:
      uri: https://sqs.us-east-2.amazonaws.com/1234567879/my_queue

我可以正常发送。但是，当我添加侦听器时，在启动过程中出现以下错误，并且侦听器未收到消息：

还有一个基本问题。 @SQSListener如何知道在哪里可以找到aws帐户信息和sqs uri？

Answer 1

我通过配置类的以下更改使它起作用。但是，我想知道，没有此代码（使用withEndpointConfiguration构造AmazonSQSAsync）的大多数示例程序如何运行。

    public QueueMessagingTemplate queueMessagingTemplate(AmazonSQSAsync amazonSQS) {
        return new QueueMessagingTemplate(amazonSQS);
    }

    @Bean
    @Primary
    public AmazonSQSAsync amazonSQS(AWSCredentialsProvider credentials) {
        return AmazonSQSAsyncClientBuilder.standard()
                .withCredentials(credentials)
                .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(localStackSqsUrl, awsRegion))
                .build();
    }

    @Bean
    @Primary
    public AWSCredentialsProvider awsCredentialsProvider() {
        return new AWSCredentialsProviderChain(
                new AWSStaticCredentialsProvider(
                        new BasicAWSCredentials("local", "stack")));
    }```

Answer 2

几件事。
-永远不要将您的AK / SK存储在这样的属性或yml文件中。我可以说那些是假值，但您总是想从〜/ .aws / credentials或实例元数据中提取它们。如果您仅调用.standard（），则像AmazonSqSAsyncClientBuilder这样的AWS客户端将自动执行。不需要凭据提供程序。
-其次，与地区相同
-第三，我相信@SqsListener将使用您之前定义的ContainerFactory bean，至少这是@JmsListener的工作方式。
-您收到的错误消息是，您在所选区域的帐户中找不到队列名称。您告诉我们us-east-1，但在发送代码中指定了us-east-2。根据您的帖子，我的猜测是，由于您的问题是关于@SqsListener而不是queueMessagingTemplate，因此您的队列位于us-east-2。
