SpringBoot整合ElasticSearch
添加依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>application.yml全局配置：
spring:
data:
elasticsearch:
cluster-nodes: 192.168.25.129:9300
local: false
repositories:
enabled: true针对上一节的案例，我们来做说明。
封装实体类：
新建包：com.qianfeng.pojo
@Document(indexName="userindex",type="user")
public class User implements Serializable{
@Id
private Long id;
private String first_name;
private String last_name;
private int age;
private String about;
private List<String> interests;
//get、set方法省略
@Override
public String toString() {
return "User[id=" + id +",first_name=" + first_name + ", last_name=" + last_name + ", age=" + age + ", about =" + about + ", interests=" + interests + "]";
}
}实现搜索：
com.qianfeng.controller：
@Controller
public class TestController {
//SpringBoot在启动时自动配置了ElasticsearchTemplate
@Autowired
private ElasticsearchTemplate elasticSearchTemplate;
@RequestMapping("/search")
@ResponseBody
public String findDoc() {
//构造搜索条件
QueryBuilder builder = QueryBuilders.existsQuery("first_name");
SearchQuery searchQuery = new NativeSearchQueryBuilder().withQuery(builder);
.build();
List<User> users=elasticSearchTemplate.queryForList(searchQuery, User.class);
for(User user:users) {
System.out.println(user);
}
return "success";
}
}在启动类中添加所有需要扫描的包：
@SpringBootApplication(scanBasePackages="com.qianfeng")执行结果：
