创建名为“compositeCompatibilityVerifier”的 bean 时出错

Question

我正在使用Spring Boot 2.5.5with Spring Cloud Version 2020.0.4，但是当我尝试运行该应用程序时，我遇到了异常 -

Exception encountered during context initialization - cancelling refresh attempt:     
org.springframework.beans.factory.BeanCreationException: Error creating bean with name  
'compositeCompatibilityVerifier' defined in class path resource [org/springframework 
/cloud/configuration/CompatibilityVerifierAutoConfiguration.class]: Bean instantiation  
via factory method failed; nested exception is 
org.springframework.beans.BeanInstantiationException: Failed to instantiate 
[org.springframework.cloud.configuration.CompositeCompatibilityVerifier]: Factory 
 method 'compositeCompatibilityVerifier' threw exception; nested exception is 
 org.springframework.cloud.configuration.CompatibilityNotMetException

            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

我有另一个项目jar，其中pom也有相同的项目Spring Boot Version，我怀疑会导致问题，但不确定如何？

Answer 1

你pom看起来不错。我唯一建议的是检查弹簧组件的兼容性。spring.io页面有一个兼容性矩阵，您应该仔细检查您尝试使用的版本是否与 Spring Boot 兼容。

您可以尝试的第二件事是根本没有父 POM，而是从其 pom-s 导入 spring boot 和 spring cloud 依赖项。

您添加了 Spring Cloud，对于 Spring Boot 执行以下操作：

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