SpringCloud系列----->SpringBoot项目中整合ElasticSearch

SpringBoot项目中整合ElasticSearch：    1、首先在maven的pom. 中加入以下配置：              <properties>          <!-- 设定和你的es版本相同的版本号，springboot默认的是2.x的版本-->          <elasticsearch.version>6.5.4</elasticsearch.version>       </properties>    2、在pom. 中增加：                     <dependency>        <groupId>org.elasticsearch.client</groupId>        <artifactId>transport</artifactId>        <version>${elasticsearch.version}</version>    </dependency>    <dependency>        <groupId>org.apache.logging.log4j</groupId>        <artifactId>log4j.core</artifactId>        <version>2.7</version>    </dependency>    3、在application.properties文件中添加              appender.console.type = Console          appender.console.name = console          appender.console.layout.type = PatternLayout          appender.console.layout.pattern = [%t] %-5p %c - %m%n          rootLogger.level = info           rootLogger.appenderRef.console.ref = console               4、在项目中新建config目录，添加EsConfig.class文件：                    @Configuration        public class EsConfig {              @Bean              public TransportClient client()  throws UnknownHostException {                      InetSocketTransportAddress  node = new  InetSocketTransportAddress(                              InetAddress.getByName("localhost"),                              9300                        );                      Settings settings = Settings.builder().put("cluster.name","biges").build();                      TransportClient client = new PreBuiltTransportClient(settings);                      client.addTransportAddress(node);                      return client;            }        }
