基于扫描方式配置：
引入依赖 <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> <version>2.1.2.RELEASE</version> </dependency>启动类添加注解：@EnableFeignClients
Config：
@Configuration public class FeigTimeOutConfigure { @Value("${fegin.connect.time.out.millis}") private Integer connectTimeOutMillis; //链接超时时间 @Value("${fegin.read.time.out.millis}") private Integer readTimeOutMillis; //响应超时时间，如果超过readTimeOutMillis秒没有接过发起下一次请求 @Value("${fegin.period}") private Integer period; //发起当前请求的时间间隔，单位毫秒 @Value("${fegin.max.period}") private Integer maxPeriod; //发起当前请求的最大时间间隔，单位毫秒 @Value("${fegin.max.attempts}") private Integer maxAttempts; //最多请求次数，包括第一次 @Bean public Request.Options options() { return new Request.Options(connectTimeOutMillis, readTimeOutMillis); } @Bean public Retryer feignRetryer() { Retryer retryer = new Retryer.Default(period, maxPeriod, maxAttempts); return retryer; } }码云：(https://gitee.com/wu_xiaoxi/spring-family/tree/master/springboot-openfegin)
