带有弹簧启动的弹性PreBuiltTransportClient会导致内存泄漏

Question

我正在使用以下代码创建弹性客户端的bean。这造成了内存泄漏。我正在使用Spring Boot 2.0.1.RELEASE和Elastic Rest Client 5.6.8。

@Bean
public Client client() throws UnknownHostException {

    Settings esSettings = Settings.builder()
            .put("cluster.name", esClusterName)
            .build();

    return new PreBuiltTransportClient(esSettings)
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(esHost), esPort));
}

Answer 1

这是众所周知的问题。

我认为您有一种解决方法

1. 您可以切换到弹性Java Rest客户端。 https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html
