Today, I will talk to you about how to use elasticsearch in springBoot. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

1 install elasticsearch

2 run elasticsearch

Docker run-d-p 9200 Xmx216m 9200-p 9300-e "ES_JAVA_OPTS=-Xms216m-Xmx216m"-- name ES01 elasticsearch:2.4.0

3 Test installation results

4 create a new springbootweb project pom.xml

4.0.0 org.springframework.boot spring-boot-starter-parent 1.5.21.RELEASE com.elasticspring-elasticsearch0.0.1-SNAPSHOTspring-elasticsearchDemo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter-data-elasticsearch Io.searchbox jest org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin

Application.properties file

Spring.elasticsearch.jest.uris= http://192.168.1.139:9200

Spring.data.elasticsearch.cluster-name=elasticsearch

Spring.data.elasticsearch.cluster-nodes=192.168.1.139:9300

Spring.data.elasticsearch.repositories.enabled=true

5 Test jest

1 create a new entity class

Public class Article {

@ JestIdprivate Integer id;private String author;private String title;private String content;public Integer getId () {return id;} public void setId (Integer id) {this.id = id;} public String getAuthor () {return author;} public void setAuthor (String author) {this.author = author;} public String getTitle () {return title;} public void setTitle (String title) {this.title = title;} public String getContent () {return content } public void setContent (String content) {this.content = content;}

}

Public class SpringElasticsearchApplicationTests {

@ Autowire JestClient jestClient

[@ Test] (https://my.oschina.net/azibug)public void contextLoads () throws IOException {Article article = new Article (); article.setId (1); article.setTitle ("jestElasticSearch"); article.setAuthor ("mao"); article.setContent ("hello this is jestElasticSearch test") / / build an index function Index index = new Index.Builder (article) .index ("mao") .type ("news") .build (); jestClient.execute (index) } [@ Test] (https://my.oschina.net/azibug)public void search () throws IOException {String index = "{\ n" + "\" query\ ": {\ n" + "\" match\ ": {\ n" + "\" content\ ":\" hello\ "\ n" + "}\ n" + "}\ n" + "}" / / build search function Search search = new Search.Builder (index) .addIndex ("mao"). AddType ("news"). Build (); SearchResult result=jestClient.execute (search); System.out.println (result.getJsonString ());}

}

2 testing using ElasticsearchRepository

Create a new Book entity

/ / specify index and type

@ Document (indexName = "mao", type = "book")

Public class Book {

Private Integer id;private String name;public Integer getId () {return id;} public void setId (Integer id) {this.id = id;} public String getName () {return name;} public void setName (String name) {this.name = name;} @ Overridepublic String toString () {return "Book {" + "id=" + id + ", name='" + name +'\'+'}';}

}

BookReposity . Java

Public interface BookReposity extends ElasticsearchRepository {

Public List findByNameLike (String name)

}

@ Autowired BookReposity bookReposity; @ Test

@ Testpublic void test2 () {Book book = new Book (); book.setId (1); book.setName ("the Strange of Youth"); bookReposity.index (book);} public void test1 () {

/ / Book book = new Book (); / / book.setId (1); / / book.setName ("the Strange of teenagers"); / / bookReposity.index (book); for (Book book:bookReposity.findByNameLike ("less")) {System.out.println (book.toString ());}}
