我要评论springcloud微服务踩坑记录
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
微服务不能启动，报错，网上修改建议一般是修改配置文件的service-name和instance-id，修改后仍然不好用。
后来解决方式是换了springcloud的版本
2.报错如下
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 [sun.misc.launcher$appclassloader@18b4aac2]
caused by: java.lang.illegalstateexception: failed to introspect class [org.springframework.cloud.context.properties.configurationpropertiesbeans] from classloader [sun.misc.launcher$appclassloader@18b4aac2]
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版本不匹配
后来版本分别选用2.2.5和hoxton.sr3解决
<parent>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-parent</artifactid>
<version>2.2.5.release</version>
</parent><properties>
<project.build.sourceencoding>utf-8</project.build.sourceencoding>
<project.reporting.outputencoding>utf-8</project.reporting.outputencoding>
<java.version>1.8</java.version>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<spring-cloud.version>hoxton.sr3</spring-cloud.version>
</properties>总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
