Examples with MicroserviceVersion org.apache.servicecomb.serviceregistry.consumer.MicroserviceVersion used on opensource projects

Example 1 with MicroserviceVersion

use of org.apache.servicecomb.serviceregistry.consumer.MicroserviceVersion in project incubator-servicecomb-java-chassis by apache.

the class ConsumerSchemaFactory method getOrCreateMicroserviceMeta.

// 透明rpc场景，因为每次指定schema调用，所以可以懒加载
// 而rest场景，是根据path反向查找schema，所以必须所有的schema都存在才行
// 两种场景可能都会来初始化，为避免管理复杂度，改为全部全量初始化
// 
// 用于rest consumer注册的场景，此时启动流程已经完成，需要主动通知listener
// microserviceName可能是本app内的微服务
// 也可能是appid:name形式的其他app的微服务
public MicroserviceMeta getOrCreateMicroserviceMeta(String microserviceName, String versionRule) {
    MicroserviceMeta microserviceMeta = microserviceMetaManager.findValue(microserviceName);
    if (microserviceMeta != null) {
        return microserviceMeta;
    }
