“请教大家一个问题 本地下载了es，启动了，也插入了数据，springboot项目写了一个测试方法查数据在执行到最后一行数据的时候报CommectionClosedException:Connection is closed 代码如下： CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(“”elastic””, “”hx6f=XCq0XcI+O9DqwUQ””)); RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost(“”127.0.0.1″”, 9200)).setHttpClientConfigCallback((HttpAsyncClientBuilder httpAsyncClientBuilder) -> httpAsyncClientBuilder.setDefaultCredentialsProvider(credentialsProvider))); // 1.准备Request GetRequest request2 = new GetRequest(“”spu””, “”1″”); // 2.发送请求，得到响应 我只引入了spring-boot-starter-data-elasticsearch依赖，另外，我的springboot版本是2.3.5RELEASE，elasticsearch版本是8.6.2。 GetResponse response = client.get(request2, RequestOptions.DEFAULT);”
