引起：java.lang.ClassNotFoundException：org.springframework.boot.context.properties.ConfigurationBeanFactoryMetadata

Question

如何修复这个错误？

这是：

原因：java.lang.ClassNotFoundException： org.springframework.boot.context.properties.ConfigurationBeanFactoryMetadata

这是我的 pom.xml 文件

Answer 1

您正在使用 Spring Boot

2.5.4

和 Spring Cloud

Hoxton.SR12

。

如 Spring Cloud 兼容性矩阵此处所述，Spring Cloud

Hoxton.SR12

与 Spring Boot

2.2.x

、

2.3.x

兼容。所以你必须选择正确的组合。

如果想简化版本选择，可以使用Spring Initializr工具。

尝试（或调整你的）以下

pom.xml

：

Answer 3

在pom.xml中使用spring版本：

  <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
  </parent>

   <properties>
        <java.version>11</java.version>
        <spring-cloud.version>Greenwich.SR2</spring-cloud.version>
   </properties>

     <dependencies>   

    <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-oauth2</artifactId>
            <version>2.0.0.RELEASE</version>
    </dependency>
     </dependencies>

        <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

你必须检查哪个版本与你的 Spring Boot 匹配 您可以从此网址检查是否有晚点
