關于RocketMQMessageChannelBinder.java:172報錯method that does not exist

背景：

為了适配nacos1.3.2，springcloud由Hoxton.RELEASE更新到Hoxton.SR7，com.alibaba.cloud****2.2.0更新到2.2.1

問題描述：

錯誤資訊如下：

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    com.alibaba.cloud.stream.binder.rocketmq.RocketMQMessageChannelBinder.createProducerMessageHandler(RocketMQMessageChannelBinder.java:172)

The following method did not exist:

    org.springframework.integration.channel.AbstractMessageChannel.getChannelInterceptors()Ljava/util/List;

The method's class, org.springframework.integration.channel.AbstractMessageChannel, is available from the following locations:

    jar:file:/xzb/5_course/xzb-course.jar!/BOOT-INF/lib/spring-integration-core-5.3.2.RELEASE.jar!/org/springframework/integration/channel/AbstractMessageChannel.class

The class hierarchy was loaded from the following locations:

    org.springframework.integration.channel.AbstractMessageChannel: jar:file:/xzb/5_course/xzb-course.jar!/BOOT-INF/lib/spring-integration-core-5.3.2.RELEASE.jar!/
    org.springframework.integration.context.IntegrationObjectSupport: jar:file:/xzb/5_course/xzb-course.jar!/BOOT-INF/lib/spring-integration-core-5.3.2.RELEASE.jar!/


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.integration.channel.AbstractMessageChannel
           

問題分析：

pom如下（未更改）：

錯誤資訊可知getChannelInterceptors()報錯：

可知由于spring-integration-core-5.3.2.RELEASE.jar報錯導緻：

官網找一下：

https://github.com/alibaba/spring-cloud-alibaba/pull/1503（無奈）

問題解決：

由于輕易更改版本太容易出錯了，那我們幹脆換回來呗，檢視下之前的版本中spring-integration-core版本為5.2.1：

更改pom：

檢視RocketMQMessageChannelBinder 173行已經不報紅了。

建議：輕易别換版本尤其是使用 com.alibaba.cloud，如果業務需要确實需要比如我這次的nacos的權限問題，建議多去官網看下。
