public class ElasticApplication {

    public static void main(String[] args) {
        SpringApplication.run(ElasticApplication.class, args);
    }

}

spring:
  data:
    elasticsearch:
      cluster-nodes: 101.37.148.209:9200
      cluster-name: njnode

 

版本控制，乐观锁控制并发

application.yml配置以后，记得到ES中将配置文件里面的cluster-name注释放开
