AWS XRay 记录器尝试在启动时检测类

Question

我正在尝试将 aws-xray-recorder-sdk-spring 库添加到现有的 Spring Boot 服务中，如 docs here 中所述。

我在启动时收到此错误：

我已将拦截器设置为在带有 @XRayEnabled 注释的类上运行，就像这样

  @Override
  @Around("@annotation(com.amazonaws.xray.spring.aop.XRayEnabled)")
  public void xrayEnabledClasses() {}

我的项目中没有spring-data，所以有点困惑为什么 AOP 会尝试匹配它。

有一个post here 提到启动时线程本地使用可能是罪魁祸首，并建议手动检测。如果可能，更愿意使用 AWS SDK，对上述错误有什么想法吗？

AWS X-Ray Recorder SDK 依赖于 InheritableThreadLocal 存储在 为了传播有关当前（子）段的信息 在整个程序的执行过程中。似乎Spring正在使用 预先实例化的 ThreadPoolExecutor 来运行它的 Bean 创建任务。 因此，“InitializerListener”段，在创建后 备用线程，不可用于 I18nCache 初始化 功能。

我遇到了同样的问题。我发现我的项目缺少 spring-data-commons 依赖项。结果，我们遇到了 org.springframework.data.repository.Repository 的 ClassNotFoundException。 Spring AOP 掩盖了异常。添加此依赖项后，我的问题得到解决。
