[Solved] springboot Error: Error creating bean with name ‘configurationPropertiesBeans‘ defined in class path

springboot Error: 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 [[email protected]]

Problem Background
1. using springboot framework type, the introduction of the springcloud dependency, version incompatibility leads to errors can not find the bean

Solution

1. Change the version number of springboot to be compatible with spring cloud, and change 2.6.2 to 2.3.1.RELEASE

    <groupId>com.yg</groupId>
    <artifactId>zipkinServer</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>

        <version>2.3.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

2. Start the project and the project operates normally

Solution

1. The firewall is not turned off

systemctl stop firewalld

Experience

1. I was tired of finding the problem. Another time, I just introduced Zipkin dependency, which was not used, and a similar error occurred.
