重现步骤

如何操作可以重现该问题：

1. 反序列化EnumMap

   public static void main(String[] args) {
       RedisSerializer<Object> serializer = new GenericFastJsonRedisSerializer(new String[]{"cn.", "com.", "java."});
       Map<ApplicationType, List<ApplicationDO>> a = new EnumMap<>(ApplicationType.class);
       ApplicationDO code = new ApplicationDO();
       code.setId(1L);
       code.setEnabled(true);
       code.setCreateTime(LocalDateTime.now());
   
       a.computeIfAbsent(ApplicationType.AI, it -> new ArrayList<>()).add(code);
       byte[] serialize = serializer.serialize(a);
       System.out.println(new String(serialize));
       HashMap<ApplicationType, List<ApplicationDO>> deserialize = (HashMap<ApplicationType, List<ApplicationDO>>) serializer.deserialize(serialize);
       System.out.println(deserialize);
       System.out.println(deserialize.getClass());
   }

   输出:

   {"@type":"java.util.EnumMap","AI":[{"@type":"cn.iocoder.yudao.module.business.dal.dataobject.application.ApplicationDO","createTime":"2024-08-09 14:35:22.967","enabled":true,"id":1L}]}

2. 反序列化 LocalDateTime 当时间为负值

 public static void main(String[] args) {
        RedisSerializer<Object> serializer = new GenericFastJsonRedisSerializer(new String[]{"cn.", "com.", "java."});
        Map<ApplicationType, List<ApplicationDO>> a = new EnumMap<>(ApplicationType.class);
        ApplicationDO code = new ApplicationDO();
        code.setId(1L);
        code.setEnabled(true);
        code.setCreateTime(LocalDateTime.MIN);   // 这里 <---<----<---------

        a.computeIfAbsent(ApplicationType.AI, it -> new ArrayList<>()).add(code);
        byte[] serialize = serializer.serialize(a);
        System.out.println(new String(serialize));
        HashMap<ApplicationType, List<ApplicationDO>> deserialize = (HashMap<ApplicationType, List<ApplicationDO>>) serializer.deserialize(serialize);
        System.out.println(deserialize);
        System.out.println(deserialize.getClass());
    }

输出:
