I have this problem because I didn’t choose the spring boot version and cloud version when I created the project by imitating the grain mall

You can check whether your springboot version is incompatible with the springcloud version

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'configurationPropertiesBeans' defined in class path resource [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans]: Factory method 'configurationPropertiesBeans' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/boot/context/properties/ConfigurationBeanFactoryMetadata

You can change the version number in the pom.xml file

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.8.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.xiaol.guliproduct</groupId>
<artifactId>product</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>product</name>

<properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.SR3</spring-cloud.version>
</properties>
