Question

我正在尝试使用groovy和grails在Elasticsearch上实现简单的CRUD操作有一段时间我能够创建一个索引，有些时候我得到了下面提到的超时异常，我已经尝试了很多方法，但没有一个是有效的。我卡在这里可以帮助我摆脱这个。 *低于例外情况我附上了我在这里使用的代码，请仔细阅读并检查是否正确

异常

*创建索引代码*

def addPerson={
    RestHighLevelClient client=ESService.getClient()
    Map<String,Object> jsonMap = new HashMap<>();
    jsonMap.put("firstName","abcd");
    jsonMap.put("lastName","xyz");
    jsonMap.put("date",new Date());
    jsonMap.put("message","Hugh data Index mapping");
    IndexRequest indexRequest = new IndexRequest("person1","hughdata","4").source(jsonMap);
    IndexResponse res =  client.index(indexRequest);
    String index = res.getIndex()
    String type = res.getType()
    String id = res.id
    long version = res.getVersion()
    DocWriteResponse.Result result = res.getResult();

    if (result == DocWriteResponse.Result.CREATED){
        println("index created = "+result)
    }
    else if (result == DocWriteResponse.Result.UPDATED){
        println("index Updated = "+result)
    }
    ["index":index,"type": type,"id":id,"version":version]
}

创建客户端代码

    class ESService {
    RestHighLevelClient client=null
    //TransportClient client=null
        def RestHighLevelClient getClient(){
            try {
                String hostname = "localhost"
                int port = 9200
                String scheme = "http"

                client = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost",9200,"http")))

                boolean pingResponse = client.ping()

                if (pingResponse == true) {
                    print("connection established..." + pingResponse);
                } else {
                    print("connection not established. Try again : " + pingResponse)
                }
                /*return client*/
            }
            catch (ElasticsearchException e){
                e.printStackTrace()
            }
            return client
        }
}

Buildconfig.groovy

 dependencies {
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
    // runtime 'mysql:mysql-connector-java:5.1.27'
    // runtime 'org.postgresql:postgresql:9.3-1100-jdbc41'
    test "org.grails:grails-datastore-test-support:1.0-grails-2.3"
    compile group: 'org.elasticsearch', name: 'elasticsearch', version: '6.0.1'
    compile group: 'org.elasticsearch.client', name: 'elasticsearch-rest-high-level-client', version: '6.0.1'
    compile('com.amazonaws:aws-java-sdk-elasticsearch:1.11.123')
    compile('com.amazonaws:aws-java-sdk-elasticloadbalancingv2:1.11.123')
