关于redisTemplate的Unexpected token (START_OBJECT), expected START_ARRAY异常

异常如下：

Could not read JSON: Unexpected token (START_OBJECT), expected START_ARRAY: need JSON Array to contain As.WRAPPER_ARRAY type information for class java.lang.Object
 

直接上解决方案：

redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setHashValueSerializer(new Jackson2JsonRedisSerializer(Object.class));
