我有hibernate和标准的问题.我有两个类:

public class Place{
    long id;
    String name;
    Set<Street> streets;
}

public class Street{
    long id;
    String name;
    Place place;
}

我现在想要编写一个方法,该方法返回一个名称的列表,例如参数中给出的名称和一个名为like参数的街道.

public List<Place> findPlaces(String name, String streetname){
    //getSession() gives me a hibernate session
    Criteria crit = getSession().createCriteria(Place.class, "place");
    crit.add(Restrictions.like("name", name+"%"));
    //Everything works fine until here
    //Last step: Sort out all places not containing a street named like streetname + "%"
}

我为最后一步尝试了不同的方法:

//streetList is a list of all streets named like streetname
crit.add(Restrictions.in("streets", streetList));

其他方式:

DetachedCriteria strasseCrit = DetachedCriteria.forClass(Street.class, …
