总体概述:使用redisTemplate实现

1.环境配置(redis配置文件):

  • .bind配置注释掉.

  • .保护模式设置为no

  • .linux防火墙开放相对应的端口或者直接关掉

  • .redis的ip和密码配置正确

  • .记住服务端口号和auth密码

2.Maven项目实现:

1.建module:redis7_study

2.改pom:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </plugins>
    </build>

</project>

3.改properties

server.port=7777

spring.application.name=redis7_study

# ========================logging=====================
logging.level.root=info
logging.level.com.atguigu.redis7=info
logging.pattern.console=%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger- %msg%n 

logging.file.name=D:/mylogs2023/redis7_study.log
logging.pattern.file=%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger- %msg%n

# ========================swagger=====================
spring.swagger2.enabled=true
#?springboot2.6.X??swagger2.9.X???documentationPluginsBootstrapper??????
#????springboot2.6.X??SpringMVC?????????AntPathMatcher???PathPatternParser?
# ??????????matching-strategy?????ant_path_matcher
spring.mvc.pathmatch.matching-strategy=ant_path_matcher

# ========================redis??=====================
spring.redis.database=0
# ???????IP
spring.redis.host=192.168.237.100
spring.redis.port=6379
spring.redis.password=123456
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-wait=-1ms
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.min-idle=0

注意要修改成自己的ip和密码,项目启动后的端口号为7777

4.主启动

package com.atguigu.redis7;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @auther zzyy
 * @create 2022-11-17 16:36
 */
@SpringBootApplication
public class Redis7Study7777
{
    public static void main(String[] args)
    {
        SpringApplication.run(Redis7Study7777.class,args);
    }
}

5.redisConfig实现序列化流:

当redis中使用springboot执行写入操作时输入中文,在redis服务当中并不能显示出中文样式,显示的却是一种乱码形式的key/value.所以才需要将数据序列化存入

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @auther zzyy
 * @create 2022-11-17 17:34
 */
@Configuration
public class RedisConfig
{
    /**
     * redis序列化的工具配置类，下面这个请一定开启配置
     * 127.0.0.1:6379> keys *
     * 1) "ord:102"  序列化过
     * 2) "\xac\xed\x00\x05t\x00\aord:102"   野生，没有序列化过
     * this.redisTemplate.opsForValue(); //提供了操作string类型的所有方法
     * this.redisTemplate.opsForList(); // 提供了操作list类型的所有方法
     * this.redisTemplate.opsForSet(); //提供了操作set的所有方法
     * this.redisTemplate.opsForHash(); //提供了操作hash表的所有方法
     * this.redisTemplate.opsForZSet(); //提供了操作zset的所有方法
     * @param lettuceConnectionFactory
     * @return
     */
    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory)
    {
        RedisTemplate<String,Object> redisTemplate = new RedisTemplate<>();

        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        //设置key序列化方式string
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //设置value的序列化方式json，使用GenericJackson2JsonRedisSerializer替换默认序列化
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());

        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());

        redisTemplate.afterPropertiesSet();

        return redisTemplate;
    }
}

  1. RedisTemplate 配置:

    • setConnectionFactory: 设置 Redis 连接工厂 (LettuceConnectionFactory)，用于建立与 Redis 的连接。
    • setKeySerializer: 设置键的序列化方式为 StringRedisSerializer，表示键将以字符串形式存储。
    • setValueSerializer: 设置值的序列化方式为 GenericJackson2JsonRedisSerializer，表示值将以 JSON 格式存储。
    • setHashKeySerializer: 设置哈希键的序列化方式为 StringRedisSerializer。
    • setHashValueSerializer: 设置哈希值的序列化方式为 GenericJackson2JsonRedisSerializer。
    • afterPropertiesSet: 确保所有属性都已设置并初始化。

这种配置使得 Redis 中的键值对和哈希表的键值都可以以 JSON 格式存储，从而方便序列化和反序列化操作

6.业务类:

在业务类中使用@resource注解导入RedisTemplate

@Resource
private RedisTemplate redisTemplate;

执行redis的set和get使用redisTemplate的各种方法就行了
