我有一个使用Jhipter生成器构建的应用程序,它基于Spring Boot.最新版本的Jhipster允许您将Elasticsearch作为选项包含在内,因此我有一个应用程序在开发模式下运行Elasticsearch的嵌入式实例,并以生产模式连接到服务器实例.

当应用程序在开发模式下运行时,它可以很好地连接到嵌入式实例,但如果我尝试连接到外部实例,我在控制台上会收到以下错误:

ERROR 7804 --- [restartedMain] .dersAbstractElasticsearchRepository:无法加载elasticsearch节点:org.elasticsearch.client.transport.NoNodeAvailableException:所有已配置的节点均不可用:[{#transport#-1} {127.0.0.1} {127.0 .0.1:9300}]

我的应用程序使用的是Spring启动版本1.4.0.RELEASE,根据elasticsearch.yml,该应用程序有弹性搜索2.3.5

我的application-prod.yml设置:

spring:
    data:
        elasticsearch:
            cluster-name: 
            cluster-nodes: localhost:9300

默认的ElasticSearchConfiguration是:

@Configuration
public class ElasticSearchConfiguration {

    @Bean
    public ElasticsearchTemplate elasticsearchTemplate(Client client, Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder) {
        return new ElasticsearchTemplate(client, new CustomEntityMapper(jackson2ObjectMapperBuilder.createXmlMapper(false).build()));
    }            
}

我覆盖了:

@Configuration
public class ElasticSearchConfiguration {
    @Value("${spring.data.elasticsearch.cluster-name}")
    private String clusterName;
    @Value("${spring.data.elasticsearch.cluster-nodes}")
    private String clusterNodes;
    @Bean
    public ElasticsearchTemplate elasticsearchTemplate() throws UnknownHostException {
            String server = clusterNodes.split(":")[0];
            Integer port = Integer.parseInt(clusterNodes.split(":")[1]);
            Settings settings = Settings.settingsBuilder()
                .put("cluster.name", clusterName).build(); …

我在java中有一个项目,我使用弹性搜索2.3.3索引数据.索引有两种类型.

我的索引文档看起来像:

{
   "took": 10,
   "timed_out": false,
   "_shards": {
      "total": 1,
      "successful": 1,
      "failed": 0
   },
  "hits": {
      "total": 3,
      "max_score": 1,
      "hits": [
        {
           "_index": "test_index",
           "_type": "movies",
           "_id": "uReb0g9KSLKS18sTATdr3A",
           "_score": 1,
           "_source": {
              "genre": "Thriller"
            }
       },
       {
           "_index": "test_index",
           "_type": "drama",
           "_id": "cReb0g9KSKLS18sTATdr3B",
           "_score": 1,
           "_source": {
              "genre": "SuperNatural"
            }
        },
        {
           "_index": "index1",
           "_type": "drama",
           "_id": "cReb0g9KSKLS18sT76ng3B",
           "_score": 1,
           "_source": {
              "genre": "Romance"
            }
         }
      ]
   }
}

我需要删除特定名称的索引和类型.

例如: -从上面的doc,我想删除名为"test_index"的索引并输入"drama". …

我正在尝试在我的 angular 9 应用程序中构建linkedin 登录功能。我将angularx-social-login npm 包用于 google 和 facebook 登录，但它不能用于linkedin。

所以我使用linkedin api来登录。

代码：-

authWindow: any;

linkedInLogin() {
    this.createOauthWindow();
}
    
createOauthWindow(width = 500, height = 600) {

    const clientId = 'my_client_id';
    const redirectUri = window.location.origin;
    const responseType = 'code';
    const scope = 'r_liteprofile';

    const url = `https://www.linkedin.com/oauth/v2/authorization?client_id=${clientId}&redirect_uri=${redirectUri}&scope=${scope}&response_type=${responseType}`;

    const left = (screen.width / 2) - (width / 2);
    const top = (screen.height / 2) - (height / 2);
    const options = `directories=no, titlebar=no, toolbar=no, location=no, status=no, menubar=no, scrollbars=no, resizable=no,
         copyhistory=no, …
