文档对像

@Document(indexName = "bigdata",type = "tag")
    public class User {
    
        @Id
    	private String openid;
        
    	private List<String> tags;
    
    	public String getOpenid() {
    		return openid;
    	}
    
    	public void setOpenid(String openid) {
    		this.openid = openid;
    	}
    
    	public List<String> getTags() {
    		return tags;
    	}
    
    	public void setTags(List<String> tags) {
    		this.tags = tags;
    	}
    
    }

配置

spring.data.elasticsearch.cluster-nodes = 10.136.15.122:9300

db层操作

package com.dongpeng.es;
    
    import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
    
    public interface UserDao  extends ElasticsearchRepository<User,String>{
    
    }

应用层

@RunWith(SpringRunner.class)
    @SpringBootTest(classes = Application.class)
    public class Test {
    
    	@Resource
    	private UserDao userDao;
    	
    	@Resource
    	private ElasticsearchTemplate elasticsearchTemplate;
    	
    	@org.junit.Test
    	public void test() {
    		User user = new User();
    		user.setOpenid("test1");
    		user.setTags(Arrays.asList("test1","test2"));
    		
    		userDao.save(user);
    		TermQueryBuilder termQueryBuilder = new TermQueryBuilder("tags", "test1");
    		TermQueryBuilder termQueryBuilder2 = new TermQueryBuilder("tags", "test2");
    		QueryBuilder queryBuilder = QueryBuilders.boolQuery().must(termQueryBuilder).must(termQueryBuilder2);
    		
    		SearchQuery searchQuery = new NativeSearchQueryBuilder()
                    .withQuery(
                    		queryBuilder
                    )
                    .withIndices("bigdata").withTypes("tag").build();
    
    	
    		System.out.println(elasticsearchTemplate.count(searchQuery));
    		
    		//System.out.println(JSON.toJSONString(userDao.search(queryBuilder)));
    	}
    }
