1.什么是Redis Search
RedisSearch 是一个基于 Redis 的搜索引擎模块它提供了全文搜索、索引和聚合功能。通过 RedisSearch可以为 Redis 中的数据创建索引执行复杂的搜索查询并实现高级功能如自动完成、分面搜索和排序。利用 Redis 的高性能特点RedisSearch 可以实现高效的搜索和实时分析。对于微服务架构来说RedisSearch 可以作为搜索服务的一部分提供快速、高效的搜索能力对于提高用户体验和性能具有重要的意义。
2.环境搭建
Docker Compose
version: 3
services:redis:image: redis/redis-stackcontainer_name: redisports:- 6379:6379redis-insight:image: redislabs/redisinsightcontainer_name: redis-insightports:- 8001:8001
Run following command:
docker-compose up -d 3.代码工程
实验目的
利用redis search 实现文本搜索功能 pom.xml

RedisHash 方式
package com.et.redis.hash;import com.redis.om.spring.annotations.Indexed;
import com.redis.om.spring.annotations.Searchable;
import org.springframework.data.annotation.Id;
import org.springframework.data.redis.core.RedisHash;RedisHash
public class Person {Idprivate String id;Indexedprivate String name;Searchableprivate String lastName;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;}public String getLastName() {return lastName;}public void setLastName(String lastName) {this.lastName lastName;}
}
package com.et.redis.hash;import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;import java.util.Optional;Repository
public interface PersonRepository extends CrudRepositoryPerson, String {OptionalPerson findByName(String name);OptionalPerson searchByLastName(String name);
}
Document 方式
package com.et.redis.document;import com.redis.om.spring.annotations.Document;
import com.redis.om.spring.annotations.Indexed;
import com.redis.om.spring.annotations.Searchable;
import org.springframework.data.annotation.Id;Document
public class Student {Idprivate String id;Indexedprivate String name;Searchableprivate String lastName;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;}public String getLastName() {return lastName;}public void setLastName(String lastName) {this.lastName lastName;}
}
package com.et.redis.document;import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;import java.util.Optional;Repository
public interface StudentRepository extends CrudRepositoryStudent, String {OptionalStudent findByName(String name);OptionalStudent searchByLastName(String name);
}

只是一些关键代码所有代码请参见下面代码仓库

4.测试
启动Spring boot应用
测试hash方式
插入一个实体 查询 模糊查询redis数据*rab* 查看redis数据库数据 redis数据库模糊查询 测试json document方式
同样的方式插入json文档然后在你redis数据库里面查看 5.引用
