使用redis报com.fasterxml.jackson.core.JsonParseException: Unexpected character ('¬' (code 172))

使用redis存储对象时,设置了redisTemplate序列化和反序列化，但是储存键值对的时候没有更改，还是使用了注解的方式，所以报了上面的错误。

参考文章：https://blog.csdn.net/m0_37224390/article/details/82051251

设置序列化：

@Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 使用Jackson2JsonRedisSerialize 替换默认序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

存储键值对不应该再使用注解方式，这种方式只能存储值为字符串的键值对。

@Autowired
    private RedisTemplate<Object,Object> stringRedisTemplate;

    @Test
    public void test(){
        ValueOperations operations=stringRedisTemplate.opsForValue();
        stringRedisTemplate.opsForValue().set(record.getToken(),record);
        User openid=(User) operations.get("1");
        System.out.println(openid.toString());
    }
