Spring-data-mongodb generic type

Question

Let's say we have a simple document type defined in mongodb：

{
  _id : OjbectId(xxx),
  value : A
}

But the value A here could be float, integer, boolean or string. How can I map it into a java entity?

Here's a template which only mapped _id:

@Document(collection = "my_document")
public class MyDocument {
  @Id
  private String id;

  public String getId() {
    return this.id;
  }

  public void setId(String id) {
    this.id = id;
  }
}

Thanks.

OK. Good. Suddenly I understand Object.

As @titogeo said in a comment, you could use Object like a generic type as it's the super type of all types.

You can read more about data mapping conversion in Spring Data MongoDB - Reference Documentation - Mapping.
