4、2 java 使用es

1、导入依赖

<dependency>
     <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

　　

2、配置

server:
  port: 9007
  
spring:
  application:
    name: tensquare‐search #指定服务名
  data:
    elasticsearch:
      cluster-nodes: 127.0.0.1:9300

　　

3、entity

package com.bw.entity;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import org.springframework.data.elasticsearch.annotations.Field;
import org.springframework.data.elasticsearch.annotations.FieldType;

@Document(indexName ="db",type="table" )
public class Article {
	@Id
	private String id;
	@Field(index = true,analyzer = "ik_max_word",searchAnalyzer = "ik_max_word",type = FieldType.Text)
	private String title;
	@Field(index = true,analyzer = "ik_max_word",searchAnalyzer = "ik_max_word",type = FieldType.Text)
	private String content;
	private String picture;
	private String status;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	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 String getPicture() {
		return picture;
	}
	public void setPicture(String picture) {
		this.picture = picture;
	}
	public String getStatus() {
		return status;
	}
	public void setStatus(String status) {
		this.status = status;
	}
	public Article() {
		super();
		// TODO Auto-generated constructor stub
	}
	public Article(String id, String title, String content, String picture, String status) {
		this.id = id;
		this.title = title;
		this.content = content;
		this.picture = picture;
		this.status = status;
	}
	@Override
	public String toString() {
		return "Article [id=" + id + ", title=" + title + ", content=" + content + ", picture=" + picture + ", status="
				+ status + "]";
	}
	
	

}

　　

4、repository

package com.bw.repository;

import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

import com.bw.entity.Article;

public interface ArticleRepository extends ElasticsearchRepository<Article, String> {

}

　　

5、测试

package com.bw;

import java.util.Iterator;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.bw.entity.Article;
import com.bw.repository.ArticleRepository;

@RunWith(SpringRunner.class)
@SpringBootTest
public class TensquareSearchApplicationTests {
	@Resource private ArticleRepository articleRepository;

	@Test
	public void contextLoads() {
		/*
		 * Article article = new
		 * Article("22","成功的程序员","这类程序员一方面很著名，另一方面在商业上也很成功，他们影响了整个工业界。他们似乎决定了工业界中发展的方向",
		 * "11", "0");
		 */
		Article article = new Article("11","不朽的程序员","你的代码比你的生命活的还长","11", "0");
		
		articleRepository.save(article);
	}
	@Test
	public void b() {
		
		  Article article = new Article("22","成功的程序员","这类程序员一方面很著名，另一方面在商业上也很成功，他们影响了整个工业界。他们似乎决定了工业界中发展的方向",
		  "11", "0");
		 

		
		articleRepository.save(article);
	}
	@Test
	public void list() {
		
		 

		
		Iterable<Article> iterable = articleRepository.findAll();
		Iterator<Article> iterator = iterable.iterator();
		while (iterator.hasNext()) {
			Article next = iterator.next();
			System.out.println(next);
		}
	}


}
