本篇文章主要介绍了SpringCloud重试机制配置详解，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
首先声明一点，这里的重试并不是报错以后的重试，而是负载均衡客户端发现远程请求实例不可到达后，去重试其他实例。
@Bean @LoadBalanced RestTemplate restTemplate() { HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(); httpRequestFactory.setReadTimeout(5000); httpRequestFactory.setConnectTimeout(5000); return new RestTemplate(httpRequestFactory); } 
feign重试机制
feign默认是通过自己包下的Retryer进行重试配置,默认是5次
package feign; import static java.util.concurrent.TimeUnit.SECONDS; /** * Cloned for each invocation to {@link Client#execute(Request, feign.Request.Options)}. * Implementations may keep state to determine if retry operations should continue or not. */ public interface Retryer extends Cloneable { /** * if retry is permitted, return (possibly after sleeping). Otherwise propagate the exception. */ void continueOrPropagate(RetryableException e); Retryer clone(); public static class Default implements Retryer { private final int maxAttempts; private final long period; private final long maxPeriod; int attempt; long sleptForMillis; public Default() { this(100, SECONDS.toMillis(1), 5); } public Default(long period, long maxPeriod, int maxAttempts) { this.period = period; this.maxPeriod = maxPeriod; this.maxAttempts = maxAttempts; this.attempt = 1; } feign取消重试
@Bean Retryer feignRetryer() { return Retryer.NEVER_RETRY; } feign请求超时设置
@Bean Request.Options requestOptions(ConfigurableEnvironment env){ int ribbonReadTimeout = env.getProperty("ribbon.ReadTimeout", int.class, 6000); int ribbonConnectionTimeout = env.getProperty("ribbon.ConnectTimeout", int.class, 3000); return new Request.Options(ribbonConnectionTimeout, ribbonReadTimeout); } 以上就是SpringCloud重试机制配置详解的详细内容，更多请关注0133技术站其它相关文章！
