Spring Data Redis

一、spring data redis的介绍

        1、什么是spring data?

                 spring data是用于简化数据库访问的开源框架，主要包括：redis、jdbc、elasticsearch

         2、什么是spring data redis？

                spring data redis是spring data下的一个子模块，作用：简化redis访问

        3、为什么用redisTemplate而不用jedis？

                springboot2.x后redisTemplate默认底层是lettuce(nio)，大并发下redisTemplate效率更高

                redisTemplate可以设置通用序列化器

        4、spring data redis的启动器

                spring-boot-starter-data-redis

二、spring data redis入门案例

        1、pom.xml

                spring-boot-stater-web、spring-boot-stater-data-redis、spring-boot-stater-test

        2、application.yml

spring:redis:cluster:nodes:- 192.168.61.131:7001- 192.168.61.131:7002- 192.168.61.131:7003- 192.168.61.131:7004- 192.168.61.131:7005- 192.168.61.131:7006

        3、config

@Configuration
public class RedisConfig {@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory){RedisTemplate<String, Object> redisTemplate = new RedisTemplate();redisTemplate.setConnectionFactory(factory);//配置通用序列化器redisTemplate.setKeySerializer(new StringRedisSerializer());redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());redisTemplate.setHashKeySerializer(new StringRedisSerializer());redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());return redisTemplate;}
}
