解决SpringBoot下Redis序列化乱码的问题

public void setRedisTemplate(RedisTemplate<String, Object> redisTemplate) {
        redisTemplate.setKeySerializer(new JdkSerializationRedisSerializer(Object.class.getClassLoader()));
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer(Object.class.getClassLoader()));
        redisTemplate.setHashKeySerializer(new JdkSerializationRedisSerializer(Object.class.getClassLoader()));
        redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer(Object.class.getClassLoader()));
        this.redisTemplate = redisTemplate;
    }

public void setRedisTemplate(RedisTemplate<String, Object> redisTemplate) {
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        this.redisTemplate = redisTemplate;
    }
