springboot集成nacos报错：java.lang.No

1、集成nacos之后项目启动报错如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bootstrapImportSelectorConfiguration': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/boot/context/properties/ConfigurationPropertiesBean

2、解决方式：

（1）nacos版本和springboot 版本不一致，更换匹配版本启动即可。把springboot更换成2.2.6.Release

• 现在修改版本

  <!-- springboot项目下 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <!--<version>2.1.6.RELEASE</version> -->
        <!--更换版本2.2.6.RELEASW-->  
        <version>2.2.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

 <!-- nacos配置-->

            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
