Spring Cloud AWS SQS 3.0.2集成Testcontainers LocalStack遇403错误求助

Spring Cloud AWS 3.x版本中，自动配置的SqsClient并未自动关联你自定义的AwsCredentialsProvider和AwsRegionProvider bean，导致客户端没有使用LocalStack的凭证和endpoint，请求无效从而抛出403安全令牌错误。

显式创建SqsClient bean并配置LocalStack相关参数，确保SQS客户端使用正确的endpoint、凭证和区域：

修改测试配置类如下：

@TestConfiguration
class TestConfig {

    @Bean
    @Primary
    fun sqsClient(): SqsClient {
        localStack.start()
        return SqsClient.builder()
            .endpointOverride(localStack.getEndpointOverride(SQS))
            .credentialsProvider(StaticCredentialsProvider.create(AwsBasicCredentials.create(localStack.accessKey, localStack.secretKey)))
            .region(Region.of(Region.EU_CENTRAL_1.id()))
            .build()
    }

    companion object {
        @JvmStatic
        val localStack: LocalStackContainer = LocalStackContainer(DockerImageName.parse("localstack/localstack:latest"))
            .withServices(SQS)
    }

    class SqsUrlInitializer : ApplicationContextInitializer<ConfigurableApplicationContext> {
        override fun initialize(applicationContext: ConfigurableApplicationContext) {
            localStack.start()
            // 创建测试队列
            localStack.execInContainer("awslocal", "sqs", "create-queue", "--queue-name", "single-queue")
            localStack.execInContainer("awslocal", "sqs", "create-queue", "--queue-name", "list-queue")
            // 无需再设置endpoint属性，已通过SqsClient配置
        }
    }
}

• 移除原来的awsCredentialsProvider和awsRegionProvider bean，直接在SqsClient中配置凭证和区域
• 标记sqsClient为@Primary，覆盖Spring Cloud AWS自动配置的客户端实例
• 确保SqsClient使用LocalStack的endpoint，所有SQS操作都会指向LocalStack容器

• 可以指定LocalStack的具体版本（如localstack/localstack:2.3.2），避免latest版本带来的兼容性问题
• 保留spring.main.allow-bean-definition-overriding=true，确保自定义SqsClient能覆盖自动配置的bean
