SpringBoot整合Elasticsearch

Spring Data整合

核心接口

a org.springframework.data.respository.Respository

b org.springframework.data.respository.CrudRespository

c org.springframework.data.respository.PagingAndSortingRespository //分页排序

d @org.springframework.data.respository.NoRespositoryBean

 

spring data 工程

是一个 用于简化 数据库访问，并支持云服务的开源框架，旨在统一个简化对各类型持久化存储，而不拘泥于是关系型数据库还是NoSQL 数据存储

 

 

springBoot 1.5.14

Elasticsearch 2.4.6 （spring data 默认只支持 2.x 版本）

 

 

打开 http://start.spring.io/

 

 

 

 

第一步 激活 Elasticsearch

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;   @SpringBootApplication @EnableElasticsearchRepositories public class SpringBootLesson9Application {   public static void main(String[] args) { SpringApplication.run(SpringBootLesson9Application.class, args); } }

配置 elasticsearch

spring.data.elasticsearch.cluster-name=elasticsearch # 多个节点用逗号隔开 spring.data.elasticsearch.cluster-nodes=192.168.255.128:9300

编写实体类

import org.springframework.data.elasticsearch.annotations.Document;   import java.io.Serializable;   @Document(indexName = "book",type = "it") public class User implements Serializable{ private String id; private String name;   public String getId() { return id; }   public void setId(String id) { this.id = id; }   public String getName() { return name; }   public void setName(String name) { this.name = name; } }

编写 repository 接口

import cn.shendu.springbootlesson9.domain.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.elasticsearch.core.ElasticsearchOperations; import org.springframework.data.elasticsearch.repository.ElasticsearchRepository; import org.springframework.data.elasticsearch.repository.support.AbstractElasticsearchRepository; import org.springframework.stereotype.Component; import org.springframework.util.Assert;   @Component public interface UserElasticsearchRepository extends ElasticsearchRepository<User,String> { }

编写 controller

import cn.shendu.springbootlesson9.domain.User; import cn.shendu.springbootlesson9.repository.UserElasticsearchRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;   @RestController public class UserController {   @Autowired private UserElasticsearchRepository userElasticsearchRepository;   @RequestMapping("/get/user") public User getUser(@RequestBody User user){ User u = userElasticsearchRepository.findOne(user.getId());   return u; }   @RequestMapping("/add/user") public String add(){ User user = new User(); user.setId("1"); user.setName("shendu"); userElasticsearchRepository.save(user); return "success"; }   }
