springBoot中elasticsearch如何使用

今天就跟大家聊聊有关springBoot中elasticsearch如何使用，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

1 安装elasticsearch

2 运行elasticsearch

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

3 测试安装结果

4 新建一个springbootweb项目 pom.xml

application.properties文件

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 测试jest

1 新建一个实体类

public class Article {

@JestId

private 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("jest ElasticSearch");
	
    article.setAuthor("mao");
	
    article.setContent("hello this is jestElasticSearch test");
	
    //构建一个索引功能
	
    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" +
            "}";
    //构建搜索功能
	
  Search search =  new Search.Builder(index).addIndex("mao").addType("news").build();
  
  SearchResult result=jestClient.execute(search);
  
    System.out.println(result.getJsonString());
	
}

}

2 测试 使用 ElasticsearchRepository

新建一个Book实体

//指明索引和类型

@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;
}

@Override
public String toString() {
    return "Book{" +
            "id=" + id +
            ", name='" + name + '\'' +
            '}';
}

}

BookReposity。java

public interface BookReposity extends ElasticsearchRepository<Book,Integer> {

public List<Book> findByNameLike(String name) ;

}

@Autowired BookReposity bookReposity; @Test

 @Test
public void test2(){
    Book book = new Book();
    book.setId(1);
    book.setName("少年的奇特");
    bookReposity.index(book);

}

public void test1(){

// Book book = new Book(); // book.setId(1); // book.setName("少年的奇特"); // bookReposity.index(book); for(Book book:bookReposity.findByNameLike("少")){ System.out.println(book.toString()); } }
