解决方法一：注释掉 objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL)

Spring源码中是使用容器中的ObjectMapper对象进行序列化和反序列化。当我们将自定义的ObjectMapper对象放入IOC容器中后，会自动覆盖SpringBoot自动装载的ObjectMapper对象。若是我们在自定义的ObjectMapper中设置了objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);属性。那么可能会影响我们的@RequestBody反序列化JSON串，将配置类的om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); 注释掉.

解决方法二：直接修改序列化方式

 将  redisUtil.set(alarmRedisPrefix + ruleKey, ruleDetail);

更改为：

redisUtil.set(RedisConfig.alarmRulePrefix + ruleKey, JSON.toJSONString(ruleDetail));

补为：若果批量导入缓存，需要进行两次序列化

public void executeResourcePipelined(List<MobileEnodebResource> list, long seconds) {
        RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
        redisTemplate.executePipelined(new RedisCallback<String>() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {

                list.forEach((value) -> {
                    connection.set(serializer.serialize(RedisConfig.nmsResourcePrefix + value.getNmsOrigResName()), 
serializer.serialize(JSON.toJSONString(value.toString()))
,Expiration.seconds(seconds), RedisStringCommands.SetOption.UPSERT);
                });
                return null;
            }
        },serializer);
    }
