SpringBoot和SpringCloud版本冲突问题

SpringBoot-2.2.2.RELEASE整合SpringCloud-Hoxton.SR6中Bus消息总线组件版本不兼容问题

问题描述

今天早上小编满脸微笑的对待SpringCloud，可以在使用Bus 消息总线组件的时候，出现bug 了，我们大家来看一下。

Description:

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

    org.springframework.cloud.function.context.config.JsonMessageConverter.<init>(JsonMessageConverter.java:47)

The following method did not exist:

    org.springframework.messaging.converter.AbstractMessageConverter.<init>([Lorg/springframework/util/MimeType;)V

The method's class, org.springframework.messaging.converter.AbstractMessageConverter, is available from the following locations:

    jar:file:/E:/User_Data/Maven_Bank/org/springframework/spring-messaging/5.2.1.RELEASE/spring-messaging-5.2.1.RELEASE.jar!/org/springframework/messaging/converter/AbstractMessageConverter.class

It was loaded from the following location:

    file:/E:/User_Data/Maven_Bank/org/springframework/spring-messaging/5.2.1.RELEASE/spring-messaging-5.2.1.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.messaging.converter.AbstractMessageConverter

解决方案

对于上述问题我也是束手无策，上面问题是springcloud中的spring-messaging-5.2.1.RELEASE.jar这个和springboot中的spring-messaging-5.2.1.RELEASE.jar存在版本冲突问题。大概在网上翻阅了1个多小时时间的资料，却无所收获。

这时候小编突然想到了之前在整合丝袜哥的时候出现的bug 大致与上述一致，我就换了一个springboot版本选择使用2.2.2.RELEASE ，然后插香磕头希望能运行。

果不其然 小编的猜猜是正确的，关于SpringBoot 和SpringCloud 版本对应官方的描述：描述地址；由于这个是JSON 格式的，小编已经为大家整理好了。

版本对应

SpringCloud-Version	SpringBoot-Version
Finchley.M2	2.0.0.M3 =< 2.0.0.M5
Finchley.M3	2.0.0.M5 <= 2.0.0.M5
Finchley.M4	2.0.0.M6 <= 2.0.0.M6
Finchley.M5	2.0.0.M7 <= 2.0.0.M7
Finchley.M6	2.0.0.RC1 <= 2.0.0.RC1
Finchley.M7	2.0.0.RC2 <= 2.0.0.RC2
Finchley.M9	2.0.0.RELEASE <= 2.0.0.RELEASE
Finchley.RC1	2.0.1.RELEASE =< 2.0.2.RELEASE
Finchley.RC2	2.0.2.RELEASE =< 2.0.3.RELEASE
Finchley.SR4	2.0.3.RELEASE =< 2.0.999.BUILD-SNAPSHOT
Finchley.BUILD-SNAPSHOT	2.0.999.BUILD-SNAPSHOT =< 2.1.0.M3
Greenwich.M1	2.1.0.M3 =< 2.1.0.RELEASE
Greenwich.SR6	2.1.0.RELEASE =< 2.1.16.BUILD-SNAPSHOT
Greenwich.BUILD-SNAPSHOT	2.1.16.BUILD-SNAPSHOT =< 2.2.0.M4

Hoxton.BUILD-SNAPSHOT	2.3.2.BUILD-SNAPSHOT =< 2.4.0.M1
2020.0.0-SNAPSHOT	2.4.0.M1 <=

目前小编使用的版本是SpringBoot 2.2.2.RELEASE SpringCloud Hoxton.SR6；暂时未遇到什么错误
