springboot整合elasticsearch7

在 Spring Boot 中整合 Elasticsearch 7 的步骤如下:
1. 在项目的 pom.xml 文件中添加 Elasticsearch 依赖:
```
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.10.0</version>
</dependency>
```
2. 在 application.properties 文件中配置 Elasticsearch 连接相关信息,如:
```
spring.data.elasticsearch.cluster-nodes=localhost:9200
```
3. 在 Spring Boot 应用启动时创建 Elasticsearch 的 RestHighLevelClient 实例,并通过 @Autowired 注入到相应的 Service 中使用。
4. 在 Service 中使用 RestHighLevelClient 操作 Elasticsearch 进行索引、查询等操作。
注意:以上是一个简单的整合步骤,还需要根据具体项目情况做相应的调整。

springboot整合elasticsearch7具体步骤
Sure, I'd be happy to help! Here are the general steps you can follow to integrate Elasticsearch 7 with Spring Boot:
1. Add Elasticseach dependency to your project
2. Configure Elasticsearch properties in application.properties
3. Create Elasticsearch template configuration class
4. Implement Elasticsearch Repository interface
5. Define Elasticsearch query methods in Repository interface
6. Inject Elasticsearch Repository to your Service class
7. Use Elasticsearch queries in your Service class
Hope this helps! Let me know if you have any further questions.
SpringBoot整合elasticsearch
好的,下面是SpringBoot整合elasticsearch的步骤:
1. 引入elasticsearch和spring-boot-starter-data-elasticsearch的依赖:
```
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>7.12.1</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
<version>2.4.5</version>
</dependency>
```
2. 配置elasticsearch连接信息:
```
spring.data.elasticsearch.cluster-nodes=localhost:9200
```
3. 创建实体类:
```
@Document(indexName = "my_index")
public class MyEntity {
@Id
private String id;
private String name;
// getter and setter
}
```
4. 创建es的Repository:
```
public interface MyRepository extends ElasticsearchRepository<MyEntity, String> {
}
```
5. 在service中使用Repository:
```
@Service
public class MyService {
@Autowired
private MyRepository myRepository;
public void save(MyEntity entity) {
myRepository.save(entity);
}
public List<MyEntity> search(String name) {
return myRepository.findByName(name);
}
}
```
6. 在controller中调用service:
```
@RestController
public class MyController {
@Autowired
private MyService myService;
@PostMapping("/save")
public void save(@RequestBody MyEntity entity) {
myService.save(entity);
}
@GetMapping("/search")
public List<MyEntity> search(@RequestParam String name) {
return myService.search(name);
}
}
```
这样就可以通过SpringBoot整合elasticsearch实现数据的增删改查了。
