帶賬號密碼的, 需要elasticsearch 設置, 也可以不用賬號密碼, 但是注意公網時, elasticsearch 端口不對外開放或者指定訪問ip # yml 的配置 ``` elasticsearch: cluster-name: elasticsearch cluster-nodes: ip:9200 check-enabled: true #賬號 username: elastic #你的elasticsearch密碼 password: password ``` # ElasticSearchConfig ``` import org.elasticsearch.client.RestHighLevelClient; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.elasticsearch.client.ClientConfiguration; import org.springframework.data.elasticsearch.client.RestClients; @Configuration public class ElasticSearchConfig { /** elasticsearch 地址 **/ @Value("${jeecg.elasticsearch.cluster-nodes}") private String esUrl; @Value("${jeecg.elasticsearch.username}") private String username; @Value("${jeecg.elasticsearch.password}") private String password; @Bean RestHighLevelClient client() { ClientConfiguration clientConfiguration = ClientConfiguration.builder() .connectedTo(esUrl) .withConnectTimeout(200000) .withSocketTimeout(200000) // 賬號密碼, 不加就注釋掉 .withBasicAuth(username, password) .build(); return RestClients.create(clientConfiguration).rest(); } } ```
