redis序列化日期格式时一直报错，要不是序列化报错，要不就是反序列化报错，查了很久终于解决了

一开始使用的LocalDateTime类型 可以序列化成功 但是年月日都分解了 但是反序列化失败 改成Date就OK了

//实体类属性上加上这个注解就行了 

//实体类属性上加上这个注解就行了 时区不加也不报错，没有测试是不是时间会对不上，大家可以测测
@JsonFormat(locale="zh", timezone="GMT+8", pattern="yyyy-MM-dd")
private Date startTime;

查询了一些资料, 大概是因为 redis-cli 不支持中文的解码, 首先需要在启动时后面追加 --raw 来添加转码操作。如果想要在redis中直接看见就是存入的JSON格式的数据，可以在进行加入redis前进行一些数据的序列化。向 redis 存放中文数据时, 出现了 /x53/x54/x78 这样的问题, 也即出现了乱码问题。

fastjson redisserializer反序列化报错
01-10
### 关于 FastJSON RedisSerializer 反序列化错误解决方案 当使用 FastJSON 作为 `RedisTemplate` 的序列化器时，可能会遇到反序列化的异常情况。这通常是因为对象在存储到 Redis 中之前未按照预期的方式进行序列化，或者读取的对象类型与实际存储的数据类型不符。 为了处理此类问题，可以采取以下措施： #### 修改配置类以适配FastJSON序列化方式 确保应用程序上下文中定义了正确的序列化策略。下面是一个基于 Spring Boot 应用程序的例子，在其中指定了如何自定义 `StringRedisTemplate` 和通用类型的 `RedisTemplate` 使用 FastJSON 进行序列化/反序列化操作[^1]。 ```java import com.alibaba.fastjson.support.spring.FastJsonRedisSerializer; import org.springframework.context.annotation.Bean; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.StringRedisSerializer; @Configuration public class RedisConfig { @Bean public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) { RedisTemplate<String, Object> template = new RedisTemplate<>(); template.setConnectionFactory(factory); // 设置键（key）的序列化采用 StringRedisSerializer 方式 template.setKeySerializer(new StringRedisSerializer()); // 设置值（value）的序列化采用 FastJsonRedisSerializer 方式 FastJsonRedisSerializer<Object> fastJsonRedisSerializer = new FastJsonRedisSerializer<>(Object.class); template.setValueSerializer(fastJsonRedisSerializer); template.setHashValueSerializer(fastJsonRedisSerializer); template.afterPropertiesSet(); return template; } } ``` #### 处理特定实体类的字段映射关系 对于某些复杂场景下可能出现的特殊字符转义等问题，则可以通过调整 JSON 转换规则来规避潜在风险。例如设置日期格式、忽略空属性等参数选项，从而提高兼容性和稳定性[^2]。 ```properties # application.properties 或者 yml 文件中添加如下配置项 spring.jackson.date-format=yyyy-MM-dd HH:mm:ss spring.jackson.time-zone=GMT+8 spring.jackson.default-property-inclusion=non_null ``` 另外值得注意的是，虽然上述方法能够有效缓解大部分情况下由于序列化引起的异常现象，但在生产环境中仍需谨慎评估业务需求并选择合适的消息中间件产品，因为像 Kafka、RabbitMQ 等专门设计用于消息传递的服务往往具备更完善的功能特性以及更高的可靠性保障[^3]。
