数据库文件视频里展示的数据库表可以使用自己有的其他数据替代不一定非要一致。
自己手敲了个工程项目包含SQL文件测试RestClient项目文件
3.1 操作索引库
设计数据表对应的mappings
PUT /movie
{mappings: {properties: {all:{type: text,analyzer: ik_max_word},movieId:{type: keyword},movieTitle:{type: text,analyzer: ik_max_word, copy_to: all},movieIntroduction:{type: text,analyzer: ik_max_word, copy_to: all},movieRating:{type: float},movieReleaseDate:{type: keyword, copy_to: all}}}
}引入依赖
propertiesjava.version1.8/java.versionelasticsearch.version7.12.1/elasticsearch.versionmybatis-plus-boot.version3.4.2/mybatis-plus-boot.version
/propertiesdependencygroupIdorg.elasticsearch.client/groupIdartifactIdelasticsearch-rest-high-level-client/artifactIdversion7.12.1/version
/dependency初始化
public class MovieIndexTest {private RestHighLevelClient client;Testvoid testInit(){System.out.println(client);}BeforeEachvoid setUp(){this.client new RestHighLevelClient(RestClient.builder(HttpHost.create(http://10.120.54.174:9200)));}AfterEachvoid close() throws IOException {this.client.close();}
}创建movie索引CREATE_MOVIE 为上面的 mappings
public class MovieIndexTest {// ...........Testvoid testCreateMovieIndex() throws IOException {// 创建RequestCreateIndexRequest request new CreateIndexRequest(movie);// 准备请求数据request.source(CREATE_MOVIE, XContentType.JSON);// 发送请求client.indices().create(request, RequestOptions.DEFAULT);}// ...........
}删除、获取判断是否存在
public class MovieIndexTest {Testvoid testDelete() throws IOException {DeleteIndexRequest deleteIndexRequest new DeleteIndexRequest(movie);client.indices().delete(deleteIndexRequest,RequestOptions.DEFAULT);}Testvoid testExists() throws IOException {GetIndexRequest getIndexRequest new GetIndexRequest(movie);boolean exists client.indices().exists(getIndexRequest, RequestOptions.DEFAULT);System.out.println(exists);}Testvoid testGet() throws IOException {GetIndexRequest getIndexRequest new GetIndexRequest(movie);GetIndexResponse getIndexResponse client.indices().get(getIndexRequest, RequestOptions.DEFAULT);System.out.println(getIndexResponse);}
