添加依赖

 <!--redis-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

配置yml

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/mydemo?useUnicode=true&characterEncoding=utf-8&serverTimezone=Hongkong
    username: root
    password: root
  redis:
    host: 127.0.0.1
    port: 6379
    password: 123456

在项目启动类配置redis序列化

   //给redis配置序列化
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        //配置序列化凡是：key序列化为：String  value序列化为JSON（默认使用Jackson）
        template.setKeySerializer(RedisSerializer.string());
        template.setValueSerializer(RedisSerializer.json());
        template.setHashKeySerializer(RedisSerializer.string());
        template.setHashValueSerializer(RedisSerializer.json());

        return template;

    }

使用redis

 @Autowired
    RedisTemplate redisTemplate;

    @Test
    public void test5() {
//        redisTemplate.setKeySerializer(new StringRedisSerializer());
//        redisTemplate.setValueSerializer(new StringRedisSerializer());
        HashMap<Object, Object> map = new HashMap<>();
        map.put("q","123");
        map.put("qq","456");
        map.put("qqq","789");

        redisTemplate.opsForValue().set("qqq", map);
        Object q = redisTemplate.opsForValue().get("qqq");
        System.out.println(q);
    }
