从 AMQP 属性映射到 MessageHeaders 时出错

Question

虽然与 RabbitMQ 通信消息被成功消费，但是，日志中显示以下警告。

**error occurred while mapping from AMQP properties to MessageHeaders**
lang.IllegalStateException: java.lang.ClassNotFoundException: Class_Name
t org.springframework.integration.mapping.support.JsonHeaders.getClassForValue(JsonHeaders.java:89) ~[spring-integration-core-5.2.4.RELEASE.jar:5.2.4.RELEASE]
    at org.springframework.integration.mapping.support.JsonHeaders.buildResolvableType(JsonHeaders.java:72) ~[spring-integration-core-5.2.4.RELEASE.jar:5.2.4.RELEASE]
    at org.springframework.integration.amqp.support.DefaultAmqpHeaderMapper.createJsonResolvableTypHeaderInAny(DefaultAmqpHeaderMapper.java:169) [spring-integration-amqp-5.2.4.RELEASE.jar:5.2.4.RELEASE].

我知道这只是一个警告，但我想知道如何避免它。

提前致谢

这已在 Spring 集成 5.2.5 中修复：https://github.com/spring-projects/spring-integration/issues/3223. Please, consider to upgrade to the latest Spring Boot 2.2.6 and it is included over there. See Spring Boot docs how to override dependency versions: https://docs.spring.io/spring-boot/docs/2.2.6.RELEASE/reference/html/using-spring-boot.html#using-boot-maven

您可以应用该 GH 问题中提到的其他解决方法。
