【问题描述】：
我们的微服务实现目前在 Spring Cloud Hoxton.SR4 上，我们已经能够在使用 Spring Boot 2.2.8.RELEASE 的同时成功处理 Spring Cloud Stream Kinesis 请求（发送 Avro 消息）。但是，在升级到 Spring Cloud Hoxton.SR5 之后，我们现在看到下面的异常堆栈跟踪，这表明 Spring Cloud Hoxton.SR5 和 org.springframework.cloud:spring-cloud-stream-schema:2.2.1.RELEASE 之间可能存在不兼容，spring-cloud-stream-schema 的最新版本我明白了在 Maven 中心可用。遇到这些异常后，我恢复到Hoxton.SR4，一切都再次按预期工作。有没有其他人遇到过这个问题或可以帮助解释可能是什么不兼容或问题？是否有即将发布的spring-cloud-stream-schema 可以解决此问题？
我们目前正在使用 org.apache.avro:avro:1.9.2 从我们的 Avro 架构中生成 Java 类的代码。
我在架构注册表服务器中看到以下日志条目（即，我的微服务用 @EnableSchemaRegistryServer 注释：
2020-06-15 | 20:18:24.214 | XNIO-1 task-1 | WARN | .w.s.m.s.DefaultHandlerExceptionResolver | Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/xml;charset=UTF-8' not supported]
以下是我的架构注册表客户端中的堆栈跟踪（即，我的微服务用 @EnableSchemaRegistryClient 注释：
java.lang.Exception: org.springframework.messaging.MessageDeliveryException: failed to send Message to channel 'account-request'; nested exception is org.springframework.web.client.HttpClientErrorException$UnsupportedMediaType: 415 Unsupported Media Type: [<Map><timestamp>2020-06-15T23:32:03.766+0000</timestamp><status>415</status><error>Unsupported Media Type</error><message>Unsupported Media Type</message><path>/</path></Map>], failedMessage=GenericMessage [payload=OMMITTED_FOR_SECURITY_REASONS]

Spring 团队的任何人都可以告诉我这是否相关吗？ github.com/spring-cloud/spring-cloud-schema-registry/issues/19
