从AMQP属性映射到MessageHeaders时出错

Question

但是，在与RabbitMQ通信成功消费消息时，日志中会显示以下警告。

**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。

提前感谢

在Spring Integration 5.2.5：https://github.com/spring-projects/spring-integration/issues/3223中已经修复了这个问题。请考虑升级到最新的Spring Boot 2.2.6，它包含在那里。请参见Spring Boot文档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GH问题中提到的其他变通方法。
