how to serialize class?

Question

When I insert a List into mongodb, there is a problem:

Exception in thread \"main\" java.lang.IllegalArgumentException: can\'t serialize class mongodb.Person         


        

Answer 1

Just implement Serializable interface in Person class.

Also it will be good to define a serialVersionUID in your class.

AFAIK, while creating POJO class in java, the class should be serializable, if it is going to be transfered over some stream, have a default constructor, and allows access to properties/fields using getter and setter methods.
