springboot2.x 整合elasticsearch5.6.3 遇到的问题

港控/mmm° 2024-04-18 20:04 14阅读 0赞

首先说明基于TransportClient整合

如果项目SpringBoot1.5.X以下的，那么elasticSearch.jar最高是2.4.4版本的，只有SpringBoot2.X+，elasticSearch.jar才是5.X+  
              如果你的SpringBoot是1.5.X以下，那你又想用elasticSearch.jar5.X+怎么办呢，那就不要用spring-boot-starter-data-elasticsearch，用原生的TransportClient实现即可。

**一 首先给出整合用到的几个文件**

application.properties文件

elasticsearch.cluster.name=elasticsearch
    #当前使用log_trace的库 , 实际开发的库.http://192.168.105.132:9200
    elasticsearch.host = 192.168.104.103
    elasticsearch.port = 9300
    #spring.elasticsearch.rest.uris=192.168.104.103:9200
    #设置为true 会出现1个异常
    management.health.elasticsearch.enabled = false

maven

java configure file

@Configuration
    public class ElasticSearchConfig {
    
        @Value("${elasticsearch.host}")
        private String esHost;
    
        @Value("${elasticsearch.port}")
        private int esPort;
    
        @Value("${elasticsearch.cluster.name}")
        private String esName;
    
        @Bean
        @Primary
        public TransportClient transportClient() {
            TransportClient client = null;
            try {
                Settings settings = Settings.builder()
                        .put("cluster.name", this.esName)
                        .put("client.transport.sniff", true)
                        .put("client.transport.ignore_cluster_name", true)
                        .build();
    
                InetSocketTransportAddress master = new InetSocketTransportAddress(InetAddress.getByName(esHost), esPort);
    
                client = new PreBuiltTransportClient(settings).
                        //如果这里
                        addTransportAddress(master);
            } catch (Exception e) {
                e.printStackTrace();
            }
            return client;
        }
    }

解决方式

关闭 actuator 对 elasticsearch 的健康检查

application.properties文件加入

management.health.elasticsearch.enabled = false

以及同时出现如下提示

这个问题有多种可能 可能多种原因

1 java api使用的是9300端口，而不是9200

2 忽略掉对clustername的检查
