添加条目后，注释为“ Lazy”的地图未更新

Question

I've the following Entity:

   class User {
    ..
    ...
    @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "id.uKey")
    @MapKey(name="id.achieveId")
    private Map<Integer, Achievement> achievements;
    ..
    ..
}

at some point I call: Hibernate.Initialize();

and this map is filled with entries from DB.

when the app continues I save new entries into the DB table.

and then I try to access the map but it doesn't contain the new entries.

Is there a way to make it aware that it needs to re-select the DB table?

Thanks

EDIT:

I add new entries like this:

public void save() {
    ..
    tx = dbs.beginTransaction();

    Achievement ua = new Achievement(key, id);
    dbs.save(ua);

    tx.commit();
}

After initializing your object, it resides in the hibernate session and this session is not designed to be updated by changes from the underlying database. Just reload the object from the database, but remove it from the session before doing so.

But maybe, what you really want is to modify the map contained in your object. That would be the OOP way. After that you could persist the entire object with Hibernate.
