Amazon SQS 消息队列 Java SDK 使用，从平台获取队列数据java SDK的引入和使用

参考官网api地址

https://docs.aws.amazon.com/zh_cn/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-java-tutorials.html

1.配置本地的安全凭据，需要事先获取到 aws_access_key_id 和aws_secret_access_key

选择以下选项之一以设置默认凭据：

• 在中设置凭证AWS本地系统上的凭证配置文件，该配置文件位于：

  • ~/.aws/credentials (在 Linux、macOS 或 Unix) 上

  • Windows 上的 C:\Users\USERNAME\.aws\credentials

此文件应包含以下格式的行：

[default]
aws_access_key_id = your_access_key_id
aws_secret_access_key = your_secret_access_key

替换您自己的AWS值的凭据值你的 _access_key_id和你的 _secret_access_key.

以上设置凭证方法是多种方法之一，我用这种方式成功了 如图

2.maven项目的pom.xml引入sdk

 <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>software.amazon.awssdk</groupId>
                <artifactId>bom</artifactId>
                <version>2.17.190</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>


<dependencies>
     <dependency>
            <groupId>software.amazon.awssdk</groupId>
            <artifactId>sqs</artifactId>
        </dependency>
        <dependency>
            <groupId>software.amazon.awssdk</groupId>
            <artifactId>s3</artifactId>
        </dependency>
    

</dependencies>

3.使用案例模板测试下可用

上边这段代码包含了发送消息，接受消息的都有了，自己在此基础上任意发挥把
