当我尝试运行我的 spring boot 应用程序时,我得到了这个异常:
org.springframework.beans.factory.BeanCreationException:在类路径资源 [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class] 中创建名为“configurationPropertiesBeans”的 bean 时出错:合并 bean 定义的后处理失败;嵌套异常是 java.lang.IllegalStateException:无法从 ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@3764951d] 内省类 [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans]
我认为这是版本不兼容。我在我的 pom.xml 中导入了 open feign,之后它就不起作用了,但我不知道如何解决这个问题。我使用 open feign 2.2.5.RELEASE。这是我的 pom.xml:

为了详细说明@M-deinum 的评论,将 Spring Boot 版本设置为
2.3.4.RELEASE
(而不是2.4.2
在我的例子中)解决了这个问题。在gradle
这意味着改变:至
