c# - BinaryFormatter 和 Deserialization Complex 对象

无法反序列化以下对象图。在BinaryFormmater上调用反序列化方法时会发生该异常:系统.Runtime.Serialization.SerializationException:Theconstructortodeserializeanobjectoftype'C'wasnotfound.C上有两个构造函数,我认为问题可能是:在序列化Binaryformatter时使用带参数的构造函数和在反序列化过程中,它需要一个无参数的构造函数。有黑客/解决方案吗?对象:[Serializable]publicclassA{Bb;Cc;publicintID{get;set;}publicA

JSON parse error: Cannot deserialize value of type `java.util.ArrayList<java.lang.String>`

问题描述:在前后端传递参数时,如果为JSON,后端使用@RequestBody对象类型接受数据,会出现500/400错误。也就是说,在前后端发送数据时,出现JSON格式转换错误,从而访问不到后台接口。不添加@RequestBody虽然可以成功访问,但是无法获取到对象数据警告内容:解决:不要使用对象类型接受,统一使用Map接收数据,就不会出现上述情况@RequestBodyMapdata取代@RequestBodyArrayListdata //http://localhost:5679/student/select4 //{"list":["计算机系","英语系"]} @PostMapping
