java - AWS XRay - 请求期间无法开始名为 'AWSSecurityTokenService' : segment cannot be found, 的子分段

Question

我正在尝试在新的 Spring Boot 应用程序中设置 AWS XRay。

我想在投入生产之前在本地进行测试。该应用程序在本地与 dynamoDB 客户端和 STS 一起运行，以承担调用 dynamo 的角色。

该服务启动正常，加载所有 bean，但是当我调用该服务时，它失败了

Failed to begin subsegment named 'AWSSecurityTokenService': segment cannot be found

当它尝试调用 dynamoDB 来保存项目时。我认为如果您添加了 aws-xray-recorder-sdk-aws-sdy 依赖项，那么像 AWSSecurityTokenService 这样的包会在请求期间自动获取上下文子段？我错过了什么？

我已将以下内容添加到 pom.xml:

有初始化代码吗？如果在请求实际进入启用 X-Ray 的服务之前进行 STS 调用(或在请求的带外)，这将导致丢失上下文异常。我们建议忽略不属于请求路径的任何调用(使用未跟踪的 AWS 客户端)或将 AWS_XRAY_CONTEXT_MISSING 环境变量设置为 LOG_ERROR:
