Ribbon 具有负载机制的resttemplate 2. WebClient 方式 也就是一种非阻塞型的restTemplate 3. feign .... ribbon 的高级封装 ### nacos作为配置中心 DataID : ${pring.cloud.nacos.config.prefix}.${spring.cloud.nacos.config.file-extension} spring.cloud.nacos.config.prefix 缺省值为${spring.application.name} spring.cloud.nacos.config.file-extension 缺省值为properties Group : ${spring.cloud.nacos.config.group}，缺省值为DEFAULT_GROUP NameSpace : namespace: 读取public的值.新建namespace执行的是id而不是name 不论用哪一种方式实现。对于指定环境的配置 spring.profiles.active=DEV、 spring.cloud.nacos.config.group=DEV_GROUP、 spring.cloud.nacos.config.namespace=83eed625-d166-4619-b923-93df2088883a）， 都不要配置在应用的bootstrap.properties中。而是在发布脚本的启动命令中， 用 -Dspring.profiles.active=DEV的方式来动态指定，会更加灵活！ http://blog.didispace.com/spring-cloud-alibaba-nacos-config-3/
