SpringBoot 報 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bootstrapImportSelectorConfiguration': Initialization of bean failed;

SpringBoot 報 Error creating bean with name 'bootstrapImportSelectorConfigurat

完整版的錯誤如下：

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

檢查下你的 spring-boot-starter-parent 版本是否和spring-cloud-starter-openfeign是否匹配

例如：博主之前引的 spring-boot-starter-parent 版本是 2.1.7.RELEASE ，spring-cloud-starter-openfeign版本是2.2.4.RELEASE 就出現了這個異常。

將版本號改為：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.9.RELEASE</version>
</parent>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

后就沒問題了
