添加注解@EnableFeignClients后报错：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'configurationPropertiesBeans' defined in class path resource [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]
- 原因:springboot与springcloud版本不一致
- 版本依赖关系(推荐使用)

查看spring-cloud-openfeign的pom.xml中spring-boot版本
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.4.13</version>
<scope>compile</scope>
</dependency>
将项目中的spring-boot也改为2.4.13
查看spring-cloud-context，升到3.0.5
还有其他服务，尽量保持一致
整合的时候,各个服务使用的spring-boot版本最好保持一致,不然可能会出现未知错误。
