# 5、Springboot整合ElasticSearch #

1.快速创建SpringBoot项目

2.导入依赖

<dependency>
                <groupId>org.elasticsearch.client</groupId>
                <artifactId>elasticsearch-rest-high-level-client</artifactId>
                <version>7.4.2</version>
    </dependency>
    
    
    <properties>
            <java.version>1.8</java.version>
            <elasticsearch.version>7.4.2</elasticsearch.version>
        </properties>

3.创建配置文件GulimallElasticSearchConfig.java

//给容器中注入一个RestHighLevelClient
    @Configuration
    public class GulimallElasticSearchConfig {
        
    
            //通用配置项
        public  static  final RequestOptions COMMON_OPTIONS;
    
        static {
        
            RequestOptions.Builder builder =RequestOptions.DEFAULT.toBuilder();
    
    
    
            COMMON_OPTIONS = builder.build();
        }
        
        @Bean
        public RestHighLevelClient esRestClient() {
        
            RestHighLevelClient client = new RestHighLevelClient(
                    RestClient.builder(
                            new HttpHost("192.168.196.128", 9200, "http")));
    
            return client;
        }
    }

4.测试，在测试test中测试

@SpringBootTest
    class GulimallSearchApplicationTests {
        
    
        @Autowired
        private RestHighLevelClient client;
    
        @Test
        void test(){
        
            System.out.println(client);
        }
    
        /**
         * 测试存储数据
         */
        @SneakyThrows
        @Test
        void test1 (){
        
            IndexRequest indexRequest = new IndexRequest("users");
            indexRequest.id("1");
            User user = new User();
            user.setName("li");
            user.setAge(18);
            String json = JSON.toJSONString(user);
            indexRequest.source(json, XContentType.JSON);
    
            IndexResponse index = client.index(indexRequest, GulimallElasticSearchConfig.COMMON_OPTIONS);
    
            System.out.println(index);
        }
    
        @Data
        class User{
        
            private  String name;
            private  Integer age;
        }
    }
