高性能的Restful服务调用客户端库,完全兼容Spring MVC 注解,基于接口和注解自动代理客户端HTTP请求,支持服务发现,负载均衡,自动熔断,降级、重试。覆盖Feign + Hystrix + Ribbon + ApacheHttpClient的功能
新生项目,可与spring cloud/spring boot配套使用,帮助微服务架构更容易落地,解决服务间最后一公里的调用问题。 欢迎贡献想法和code~

// 使用@EnableRestyPass注解启用RestyPass
@SpringBootApplication
@EnableRestyPass(basePackages = {"df.open"})
@RestController
//@EnableDiscoveryClient
//启用spring cloud 服务发现则RestyPass自动使用spring的服务发现方式,
// 否则默认读取resty-server.yaml来获取服务实例
// 可自定义其它发现服务的方式,实现ServerContext接口并注入即可
