public class SpringDataRedisStringTemplateTests{
    @Autowired
    private RedisTemplate redisTemplate;
    @Test
    void testString() {
        redisTemplate.opsForValue().set("name","虎哥");
        Object name = redisTemplate.opsForValue().get("name");
        System.out.println("name = " + name);
    }
}

SpringDataRedis 默认序列化的方式是 JdkSerializationRedisSerializer
缺点：

• 可读性差
• 内存占用较大

改进

我们可以自定义 RedisTemplate 的序列化方式，且引入 jackon 依赖

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory connectionFactory){
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        //设置连接工厂
        template.setConnectionFactory(connectionFactory);

        //设置JSON的序列化工具
        GenericJackson2JsonRedisSerializer jsonRedisSerializer = new GenericJackson2JsonRedisSerializer();

        //设置key的序列化方式为 StringRedisSerializer
        template.setKeySerializer(RedisSerializer.string());
        template.setHashKeySerializer(RedisSerializer.string());

        //设置value的序列化方式为 GenericJackson2JsonRedisSerializer
        template.setValueSerializer(jsonRedisSerializer);
        template.setHashValueSerializer(jsonRedisSerializer);

        return template;
    }
}
