[BUG] 反序列化异常, EnumMap 以及 为负值的LocalDateTime 反序列化异常
问题描述
简要描述您碰到的问题。 1: 反序列化 EnumMap 2: 当LocalDateTime 为负值时报错
环境信息
请填写以下信息：
- OS信息： Darwin Mac-mini.local 23.5.0 Darwin Kernel Version 23.5.0: Wed May 1 20:09:52 PDT 2024; root:xnu-10063.121.3~5/RELEASE_X86_64 x86_64
- JDK信息：
openjdk version "1.8.0_372"
OpenJDK Runtime Environment (Temurin)(build 1.8.0_372-b07)
OpenJDK 64-Bit Server VM (Temurin)(build 25.372-b07, mixed mode)
- 版本信息：
Maven: com.alibaba.fastjson2:fastjson2:2.0.51
Maven: com.alibaba.fastjson2:fastjson2-extension:2.0.51
Maven: com.alibaba.fastjson2:fastjson2-extension-spring5:2.0.51
重现步骤
如何操作可以重现该问题：
- 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:

- 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());
}
