将 Spring Cloud(Finchley.M8) 依赖添加到 Spring Boot(2.0.6.RELEASE) 项目后，出现异常:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.endpoint.web.ServletEndpointRegistrar]: Factory method 'servletEndpointRegistrar' threw exception; nested exception is java.lang.IllegalArgumentException: Value must only contain valid chars

最佳答案
我在启动 springCloudConfigServer 项目时遇到了同样的异常。
根本原因是 application.properties 中以下属性的值不正确(拼写错误)
之前: management.endpoints.web.exposure.include=bus=refresh
我将其更改如下，我的项目成功启动 management.endpoints.web.exposure.include=总线刷新
