Eureka续约服务接口比较简单,跟注册接口一样,在DiscoveryClient类
DiscoveryClient.java
boolean renew() { EurekaHttpResponsehttpResponse; try { //调用更新心跳时间接口 httpResponse = eurekaTransport.registrationClient.sendHeartBeat(instanceInfo.getAppName(), instanceInfo.getId(), instanceInfo, null); logger.debug(PREFIX + "{} - Heartbeat status: {}", appPathIdentifier, httpResponse.getStatusCode()); //如果返回是404,则就是服务被剔除,需要重新注册 if (httpResponse.getStatusCode() == Status.NOT_FOUND.getStatusCode()) { REREGISTER_COUNTER.increment(); logger.info(PREFIX + "{} - Re-registering apps/{}", appPathIdentifier, instanceInfo.getAppName()); long timestamp = instanceInfo.setIsDirtyWithTime(); boolean success = register(); if (success) { instanceInfo.unsetIsDirty(timestamp); } return success; } return httpResponse.getStatusCode() == Status.OK.getStatusCode(); } catch (Throwable e) { logger.error(PREFIX + "{} - was unable to send heartbeat!", appPathIdentifier, e); return false; } }
JerseyReplicationClient.java这块继承AbstractJerseyEurekaHttpClient,代码差不多,主要流程没什么区别,这里给出AbstractJerseyEurekaHttpClient的逻辑,其实就是调用服务端接口
@Override public EurekaHttpResponsesendHeartBeat(String appName, String id, InstanceInfo info, InstanceStatus overriddenStatus) { String urlPath = "apps/" + appName + '/' + id; ClientResponse response = null; try { WebResource webResource = jerseyClient.resource(serviceUrl) .path(urlPath) .queryParam("status", info.getStatus().toString()) .queryParam("lastDirtyTimestamp", info.getLastDirtyTimestamp().toString()); if (overriddenStatus != null) { webResource = webResource.queryParam("overriddenstatus", overriddenStatus.name()); } Builder requestBuilder = webResource.getRequestBuilder(); addExtraHeaders(requestBuilder); response = requestBuilder.put(ClientResponse.class); EurekaHttpResponseBuilder eurekaResponseBuilder = anEurekaHttpResponse(response.getStatus(), InstanceInfo.class).headers(headersOf(response)); if (response.hasEntity() && !HTML.equals(response.getType().getSubtype())) { //don't try and deserialize random html errors from the server eurekaResponseBuilder.entity(response.getEntity(InstanceInfo.class)); } return eurekaResponseBuilder.build(); } finally { if (logger.isDebugEnabled()) { logger.debug("Jersey HTTP PUT {}/{}; statusCode={}", serviceUrl, urlPath, response == null ? "N/A" : response.getStatus()); } if (response != null) { response.close(); } } }
