Redis 反序列化失败

问题

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of org.springframework.security.core.authority.SimpleGrantedAuthority (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator) at [Source: (byte[])"…

原序列化配置

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

        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();

        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        // 使用 StringRedisSerializer 来序列化和反序列化key 的值
        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        // hash的key也采用StringRedisSerializer 的序列化方式
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

修改配置

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

        // String的序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // json序列化配置
        GenericFastJsonRedisSerializer fastJsonRedisSerializer = new GenericFastJsonRedisSerializer();

         // key采用String的序列化方式
        redisTemplate.setKeySerializer(stringRedisSerializer);
        // value的序列化方式采用fastJson的方式
        redisTemplate.setValueSerializer(fastJsonRedisSerializer);
        // hash的key也采用String 的序列化方式
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        // hash的value序列化方式采用fastJson
        redisTemplate.setHashValueSerializer(fastJsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

解决方法

使用 GenericFastJsonRedisSerializer替换 GenericFastJsonRedisSerializer
