Spring Data elasticsearch与elasticsearch版本支持
简单的使用步骤
1.引入依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
2.application.yml配置端口
spring:
data:
elasticsearch:
cluster-name: elasticsearch
cluster-nodes: 192.168.56.101:9300
3.实体类写入注解，并配置映射字段
分片shards以及备份replicas都可以在Document里面配置
id注解一定是springdata里面的
4.创建索引库以及映射
5.添加索引
这里用到ElasticsearchRepository接口，类似通用mapper
使用：
根据方法名自定义接口方法
命名合符规范即可自动实现
| Keyword | Sample | Elasticsearch Query String |
|---|---|---|
And |
findByNameAndPrice |
{"bool" : {"must" : [ {"field" : {"name" : "?"}}, {"field" : {"price" : "?"}} ]}} |

findByName |
{"bool" : {"must" : {"field" : {"name" : "?"}}}} |

findByNameNot |
{"bool" : {"must_not" : {"field" : {"name" : "?"}}}} |

findByPriceBetween |
{"bool" : {"must" : {"range" : {"price" : {"from" : ?,"to" : ?,"include_lower" : true,"include_upper" : true}}}}} |
LessThanEqual |
findByPriceLessThan |
{"bool" : {"must" : {"range" : {"price" : {"from" : null,"to" : ?,"include_lower" : true,"include_upper" : true}}}}} |

{"bool" : {"must" : {"range" : {"price" : {"from" : ?,"to" : null,"include_lower" : true,"include_upper" : true}}}}} |

After |
findByPriceAfter |
{"bool" : {"must" : {"range" : {"price" : {"from" : ?,"to" : null,"include_lower" : true,"include_upper" : true}}}}} |
Like |
findByNameLike |
{"bool" : {"must" : {"field" : {"name" : {"query" : "?*","analyze_wildcard" : true}}}}} |
StartingWith |
findByNameStartingWith |
{"bool" : {"must" : {"field" : {"name" : {"query" : "?*","analyze_wildcard" : true}}}}} |
EndingWith |
findByNameEndingWith |
{"bool" : {"must" : {"field" : {"name" : {"query" : "*?","analyze_wildcard" : true}}}}} |
Contains/Containing |
findByNameContaining |
{"bool" : {"must" : {"field" : {"name" : {"query" : "**?**","analyze_wildcard" : true}}}}} |
In |
findByNameIn(Collection<String>names) |
{"bool" : {"must" : {"bool" : {"should" : [ {"field" : {"name" : "?"}}, {"field" : {"name" : "?"}} ]}}}} |
NotIn |
findByNameNotIn(Collection<String>names) |
{"bool" : {"must_not" : {"bool" : {"should" : {"field" : {"name" : "?"}}}}}} |
Near |
findByStoreNear |
Not Supported Yet ! |
True |
findByAvailableTrue |
{"bool" : {"must" : {"field" : {"available" : true}}}} |
False |
findByAvailableFalse |
{"bool" : {"must" : {"field" : {"available" : false}}}} |
OrderBy |
findByAvailableTrueOrderByNameDesc |
{"sort" : [{ "name" : {"order" : "desc"} }],"bool" : {"must" : {"field" : {"available" : true}}}} |
举例：
public interface ItemRepository extends ElasticsearchRepository<Item,Long> {
/**
* 根据价格区间查询
* @param price1
* @param price2
* @return
*/
List<Item> findByPriceBetween(double price1, double price2);
}
不需要实现类 可以直接查询
分页的话 需要传入一个Pageable的参数，两个变量 page和size
