 Therefore, readiness check is an indispensable part of deployment automation in production environment and SOFABoot provides the readiness check for application out of box.
 For reliable application startup, all SOFAStack middleware services won't reveal themselves (e.g., RPC services publishing to Service Registry) until readiness check passes.

 针对 Spring Boot 缺少 Readiness Check 能力的情况，SOFABoot 增加了 Spring Boot 现有的健康检查的能力，提供了 Readiness Check 的能力。利用 Readiness Check 的能力，SOFA 中间件中的各个组件只有在 Readiness Check 通过之后，才将流量引入到应用的实例中，比如 RPC，只有在 Readiness Check 通过之后，才会向服务注册中心注册，后面来自上游应用的流量才会进入。
 
-除了中间件可以利用 Readiness Check 的事件来控制流量的进入之外，PAAS 系统也可以通过访问 `http://localhost:8080/health/readiness` 来获取应用的 Readiness Check 的状况，用来控制例如负载均衡设备等等流量的进入。
