Spring Cloud微服務踩坑記錄

consul

1.nested exception is java.lang.IllegalArgumentException: Consul service ids must not be empty, must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen:null

微服務不能啟動，報錯，網上修改建議一般是修改配置檔案的service-name和instance-id，修改後仍然不好用。後來解決方式是換了springcloud的版本

2.報錯如下

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘configurationPropertiesBeans’ defined in class path resource [org/springframework/cloud/autoconfigure/ConfigurationPropertiesRebinderAutoConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans] from ClassLoader [[email protected]]

Caused by: java.lang.IllegalStateException: Failed to introspect Class [org.springframework.cloud.context.properties.ConfigurationPropertiesBeans] from ClassLoader [[email protected]]

Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/context/properties/ConfigurationBeanFactoryMetadata

Caused by: java.lang.ClassNotFoundException: org.springframework.boot.context.properties.ConfigurationBeanFactoryMetadata

原因：springboot版本和Spring cloud版本不比對，後來版本分别選用2.2.5和Hoxton.SR3解決
