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

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()); } }
