项目结构图

1、pom文件添加依赖

1.依赖版本springboot会自动匹配，所以不用关注
2.fastjson依赖方便我们管理json格式数据

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
   <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.72</version>
</dependency>

2、yml文件配置连接

redis安装教程请移步查看: docker快速安装redis（两步轻松搞定）

port：端口号
host：ip地址
password：密码

spring:
  redis:
    port: 6379
    host: 127.0.0.1
    password: 123456

3、添加序列化配置类

package com.phy.demo.config;

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;

/**
 * redis 序列化配置
 * @author phy
 */
@Configuration
public class RedisConfig {
    /**
     * redis序列化配置
     * @param connectionFactory 连接工厂
     * @return
     */
    @Bean
    public RedisTemplate redisTemplate(LettuceConnectionFactory connectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(connectionFactory);
        // 替换默认序列化
        GenericJackson2JsonRedisSerializer jackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

至此，springboot整合redis并设置序列化就已完成，下面我们测试一下

测试

添加一个DemoController

package com.phy.demo.controller;

import com.alibaba.fastjson.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.*;

/**
 * demo redis 前端控制器
 * @author phy
 * @since 2021-09-29
 */
@RestController
@RequestMapping("/demo")
public class DemoController {
    @Autowired
    private RedisTemplate redisTemplate;

    @PostMapping("set")
    public void set(@RequestBody JSONObject data) {
        redisTemplate.opsForValue().set(data.get("key"),data.get("value"));
    }

    @GetMapping("get")
    public String get(String key) {
        return (String)redisTemplate.opsForValue().get(key);
    }
}

运行项目，Postman调用测试

添加redis键

通过键获取值
