+     配置dubbo服务重试次数.
+--- 
+Dubbo 服务在尝试调用一次之后，如出现非业务异常(服务突然不可用、超时等)，Dubbo 默认会进行额外的最多2次重试.
+
+重试次数支持两种自定义配置: 1.通过注解/xml进行固定配置；2.通过上下文进行运行时动态配置
+
+
+## 示例
+
+通过注解/xml进行固定配置
+
+```xml
+<dubbo:consumer retries="2"></dubbo:consumer>
+```
+
+通过RpcContext进行运行时动态配置，优先级高于注解/xml进行的固定配置(两者都配置的情况下，以RpcContext配置为准).
+
+```Java
+// dubbo服务调用前，通过RpcContext动态设置本次调用的重试次数
+RpcContext rpcContext = RpcContext.getContext();
+rpcContext.setAttachment("retries", 5);
+
+```
