SpringCloud中的服务接口(api)

作者：偷代码的猫

这篇文章主要介绍了SpringCloud中的服务接口(api),具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教

SpringCloud服务接口(api)

SpringCloud的服务接口基本等同于SpringBoot开发的api接口

只不过在springCloud需要将自己的服务注册到注册中心，通过网关统一访问路径

一个简单的api接口

基本代码与我们常写得api接口无异，只是在application.properties文件中添加了注册中心的路径

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脚本之家。
