Cannot serialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.io.NotSerializableException: com.wanmait.dormitorysystem.entity.StudentInfo

这个错误是因为com.wanmait.dormitorysystem.entity.StudentInfo类没有实现java.io.Serializable接口,导致对象无法进行序列化。在Spring Boot中,如果需要将对象进行序列化并存储到Redis等缓存中,则需要确保该对象实现了Serializable接口。Serializable接口是Java提供的用于序列化和反序列化对象的接口。实现了Serializable接口的对象可以被序列化成二进制流并存储到磁盘或网络中,也可以从二进制流中反序列化出对象。因此,如果需要将对象进行序列化,就需要确保该对象实现了Serializable接口。

org.springframework.core.serializer.support.SerializationFailedException
This exception is thrown when serialization of an object fails. It is a checked exception, which means that it must be caught or declared to be thrown in a method signature.
The org.springframework.core.serializer.support.SerializationFailedException is part of the Spring Framework and is used by serialization and deserialization components to indicate that serialization has failed. This can happen for a number of reasons, such as if the object being serialized is not serializable, or if there is a problem with the serialization process itself.
Some common causes of this exception include:
- The object being serialized is not serializable.
- The serialization process is unable to handle a particular type of object.
- There is not enough memory available to complete the serialization process.
- There is a problem with the serialization code, such as a bug or error in the implementation.
To resolve this issue, you should review the code that is performing the serialization and ensure that it is properly handling all of the objects that it may be asked to serialize. If the object being serialized is not serializable, you may need to modify it or use a different serialization approach. Additionally, you may need to allocate more memory to the process or investigate any errors or bugs in the serialization code.
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: Failed to serialize object of type: class com.sinosoft.common.mq.Monitor] with root cause
这个异常是由于序列化对象失败引起的。当你使用Java的对象序列化功能时,如果对象的类没有实现 Serializable 接口,或者对象中包含无法序列化的成员变量,都会导致序列化失败并抛出这个异常。
在你的代码中,出现了一个类型为 com.sinosoft.common.mq.Monitor 的对象,但是该对象无法被序列化。你需要检查该对象的类定义,确保它实现了 Serializable 接口,并且其中的所有成员变量都是可序列化的。如果有不可序列化的成员变量,你可以将它们标记为 transient,或者实现 Externalizable 接口并手动编写序列化和反序列化方法来处理它们。
