Mongodb saves list of object

问题

I know how to save a list of String

Now, e.g. I create my own Animal class

But when I try to save list in mongodb, it gives

java.lang.IllegalArgumentException: can't serialize class Project

I do create a new mongo collection Animal， but it is still not working.

回答1:

You might check out Morphia or similar, where you can create object models and save them directly to Mongo.

回答2:

If Animal class extend ReflectionDBObject then you can insert list of Animals.

Animal extends ReflectionDBObject {

}
