疑难问题1

2：集合 和数组的区别？arrayList

 2.1--数组 --长度固定的

 2-2 arrayList 属于类集框架的一种类型

@Configuration
public class MallElasticSearchConfiguraction {

public static final RequestOptions COMMON_OPTIOINS;
static {
RequestOptions.Builder builder= RequestOptions.DEFAULT.toBuilder();
COMMON_OPTIOINS =builder.build();
}
@Bean
public RestHighLevelClient restHighLevelClient(){
RestClientBuilder builder = RestClient.builder(new HttpHost("192.168.110.222",9200,"http"));
RestHighLevelClient client = new RestHighLevelClient(builder);
return client;
}
}
