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
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
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
public ListfindByNameLike(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()); } }
测试结果
