Spring Cloud 1.0.0.RC1 发布，此版本现已提供在 http://repo.spring.io 和 Maven 库。 值得关注的新特性如下： 通过一个注解 @EnableTurbine 和 @EnableTurbineAmqp 支持 Hystrix 指标聚合 (for an AMQP-based collector) 新增一个 rehaul 的 Ribbon 配置，提升了 Spring 用户体验 DiscoveryHealthIndicator is now a composite that users can add information to by declaring @Beans of type DiscoveryHealthIndicator. Discovery is now abstracted away from Eureka into a new spring-cloud-commons library, and enabled via new annotations like @EnableDiscoveryClient (instead of the old @EnableEurekaClient). The same pattern also applies to circuit breakers and @EnableCircuitBreaker replaces @EnableHystrix. Several improvements to the Zuul proxy, including automatic updates when the Eureka catalog changes, support for form-encoded POSTs, external configuration of the routes and authentication scheme for each client. Declarative configuration of which routes require OAuth2 authentication in Spring Cloud Security. Support for labels (like git branches) in the “native” profile of the Config Server (looks in subdirectory of the search locations). Fail fast option in Config Server and Client if the required URI to locate config data is invalid. Out of the box support for JSON messages in the Spring Cloud Bus. A nice framework for Feign configuration based on a new @FeignClient annotation (a bit like Spring Data repositories). 一些 bus 和 Starters 已经被重新组织和重新命名，同时有（可选的）父母 pom 提供给用户应用，starters 完整列表： spring-cloud-starter: provides the config client and basic Spring Boot dependencies spring-cloud-starter-bus-amqp: for bus clients over AMQP spring-cloud-starter-cloudfoundry: Cloud Foundry specific features spring-cloud-starter-eureka: service discovery client with Netflix Eureka spring-cloud-starter-eureka-server: service discovery server with Netflix Eureka spring-cloud-starter-hystrix: circuit break client with Netflix Hystrix spring-cloud-starter-hystrix-dashboard: circuit break dashboard with Netflix Hystrix spring-cloud-starter-security: single sign on and OAuth2 resource server short cuts spring-cloud-starter-turbine: HTTP-based Hystrix metric aggregation with Netflix Turbine 1.0 spring-cloud-starter-turbine-amqp: AMQP-based Hystrix metric aggregation with Netflix Turbine 2.0 spring-cloud-starter-zuul: basic Zuul proxy with auto-registration of discovered services 更多内容请看发行说明。 Spring Cloud 为开发者提供了在分布式系统（如配置管理、服务发现、断路器、智能路由、微代理、控制总线、一次性 Token、全局锁、决策竞选、分布式会话和集群状态）操作的开发工具。使用 Spring Cloud 开发者可以快速实现上述这些模式。 Spring Cloud 1.0.0.RC1 发布下载地址
