如何在使用 Jackson 序列化期间更改 class 名称

Question

'us.package.high.MyClass' is not in the trusted packages: java.util, java.lang,us.package.low.MyClass

Classes are identical. How can I change typeId (Class name) during serialization? Now it's 'us.package.high.MyClass', but I need make it just 'MyClass';

Answer 1

Using the @JsonTypeInfo annotation of Jackson:

package us.package.high.MyClass;

@JsonTypeInfo(include=As.WRAPPER_OBJECT, use=Id.NAME)
public class MyClass {

...

}

If you are using Jackson to handle JSON, it will help.

If you are using another library, search about that feature.

If you are using no library to handle JSON, try to implement a toString() method and in fact implements the Serializable interface:

public  class MyClass  implements Serializable { \\... }
