Error creating bean with name 'configDataContextRefresher' defined in class path resource

问题原因：在创建springboot项目的时候,引入了cloud的相关组件,但是后面springboot的版本太高,So I manually downgraded the version.问题来了,此时的springboot和cloudThe version does not correspond,The following is the version compatibility table of the two,Please check and modify the corresponding version by yourself.

例如我的springboot版本为2.2.3,

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

那么对应的springcloud版本为H,Spring Cloud Alibaba版本为2.1.0

<dependencyManagement>
        <dependencies>
            <!--Spring Cloud-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!--Spring Cloud Alibaba-->
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>2.1.0.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>
