首先聲明一點，這裡的重試並不是報錯以後的重試，而是負載均衡客戶端發現遠程請求實例不可到達後，去重試其他實例。
@Bean@LoadBalancedRestTemplate restTemplate() { HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(); httpRequestFactory.setReadTimeout(5000); httpRequestFactory.setConnectTimeout(5000); return new RestTemplate(httpRequestFactory);}feign重試機制
feign默認是通過自己包下的Retryer進行重試配置,默認是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取消重試
@Bean Retryer feignRetryer() { return Retryer.NEVER_RETRY; } feign請求超時設置
@BeanRequest.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);}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
