今天給項目搭建了個springboot-admin，一直報錯，，經過查找，懷疑是版本不一致原因，經過測試，admin-server的版本要低於等於admin-client的版本，否則會無法註冊進服務，報錯如下
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registrator' defined in class path resource [de/codecentric/boot/admin/client/config/SpringBootAdminClientAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [de.codecentric.boot.admin.client.registration.ApplicationRegistrator]: Factory method 'registrator' threw exception; nested exception is java.lang.NoSuchMethodError: org.springframework.boot.web.client.RestTemplateBuilder.setConnectTimeout(Ljava/time/Duration;)Lorg/springframework/boot/web/client/RestTemplateBuilder;
