Hi，大家好，我是悟纤。我就是我，不一样的烟火。我就是我，与众不同的小苹果。
这一节来看下在SpringBoot中如何集成ElasticSearch。
一、Spring Boot整合ElasticSearch
这里有一个版本的对应情况，最好对应上会比较好，不然会出现莫名其妙的问题。
https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#new-features.5-1-0
1.1 创建项目
根据相应的版本，选择相应的Spring Boot版本，这里选择的是3.1.4版本。
1.2 添加依赖
在pom.xml文件添加依赖：
<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-elasticsearch</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies>
1.3 添加配置
在配置文件application.properties中添加配置：
spring.elasticsearch.uris = http://localhost:9200spring.elasticsearch.connection-timeout = 3s
1.4 创建实体
创建实体，使用@Field注解，添加字段在ES中的类型以及使用的分词器：
(indexName = "employees")public class Employee {private Long id;(type= FieldType.Keyword)private String name;private int sex;private int age;(type= FieldType.Text,analyzer="ik_max_word")private String address;private String remark;}
1.5实现ElasticsearchRepository
该接口是框架封装的用于操作Elastsearch的高级接口：
public interface EmployeeRepository extends ElasticsearchRepository<Employee, Long> {List<Employee> findByName(String name);}
1.6测试
@AutowiredEmployeeRepository employeeRepository;@Testvoid test() {Employee employee = new Employee(1L,"悟纤",1,32,"福建福州","love coding");//插入文档employeeRepository.save(employee);//根据id查询Optional<Employee> result = employeeRepository.findById(1L);System.out.println(String.valueOf(result.get()));//根据name查询List<Employee> list = employeeRepository.findByName("悟纤");System.out.println(list.get(0));}
1.7使用ElasticsearchTemplate
@Resourceprivate ElasticsearchTemplate elasticsearchTemplate;@Testpublic void testCreateIndex(){//创建索引IndexOperations indexOperations = elasticsearchTemplate.indexOps(IndexCoordinates.of("employee_index"));if (indexOperations.exists()) {System.out.println("索引已经存在");}else {//创建索引indexOperations.create();}}@Testpublic void testDeleteIndex(){//删除索引IndexOperations indexOperations = elasticsearchTemplate.indexOps(IndexCoordinates.of("employee_index"));indexOperations.delete();}@Testpublic void testQueryDocument(){NativeSearchQueryBuilder builder = new NativeSearchQueryBuilder();//查询//builder.withQuery(QueryBuilders.matchQuery("address","公园"));// 设置分页信息builder.withPageable(PageRequest.of(0, 5));// 设置排序//builder.withSort(SortBuilders.fieldSort("age").order(SortOrder.DESC));SearchHits<Employee> search = elasticsearchTemplate.search(builder.build(), Employee.class);List<SearchHit<Employee>> searchHits = search.getSearchHits();for (SearchHit hit: searchHits){System.out.println("返回结果："+hit.toString());}}@Testpublic void testInsertBatch() throws JsonProcessingException {List<Employee> employees = new ArrayList<>();employees.add(new Employee(2l,"张三",1,25,"广州天河公园","java developer"));employees.add(new Employee(3l,"李四",1,28,"广州荔湾大厦","java assistant"));employees.add(new Employee(4l,"小红",0,26,"广州白云山公园","php developer"));List<IndexQuery> queries = new ArrayList<>();for (Employee employee : employees) {IndexQuery indexQuery = new IndexQuery();indexQuery.setId(employee.getId().toString());ObjectMapper mapper = new ObjectMapper();String json = mapper.writeValueAsString(employee);indexQuery.setSource(json);queries.add(indexQuery);}//bulk批量插入elasticsearchTemplate.bulkIndex(queries,Employee.class);}
基本的集成用起来害死很简单的，关键在如何在实际的项目中进行合理的使用，这个是需要在具体的实战中进行自我摸索和探究的。
