java.lang.NoClassDefFoundError: integration/config/HandlerMethodArgumentResolversHolder

在使用spring-cloud-starter-bus-amqp时报错java.lang.NoClassDefFoundError: org/springframework/integration/config/HandlerMethodArgumentResolversHolder。

环境说明：
springcloud ： Finchley.SR2
springboot ： 2.1.1.RELEASE

<dependency>
      <groupId>org.springframework.cloudgroupId>
      <artifactId>spring-cloud-starter-bus-amqpartifactId>
dependency>

错误原因是springcloud的版本与springboot版本不一致造成的。

springcloud与springboot的版本对应关系请参考 https://start.spring.io/actuator/info 。

解决办法：
由于我这里使用的是springcloud ： Finchley.SR2，该版本对应的springboot版本是Spring Boot >=2.0.3.RELEASE and <2.0.999.BUILD-SNAPSHOT。所以我们将springboot降级版本即可。
