Question

我在用户和项目之间存在“多对多”关系：

用户类：

@ManyToMany ( fetch = FetchType.EAGER )//Tipo de busqueda
@JoinTable(name="USERPROJECTS" //Tabla de intercambio
, joinColumns={@JoinColumn(name="IDUSER") //Llave foránea
}
, inverseJoinColumns={@JoinColumn(name="IDPROJECT") //Llave foránea
})
@Where( clause = "DELETIONDATE is null" )
private List<Project> projects;

项目类：

@ManyToMany(cascade=CascadeType.ALL) //Tipo de busqueda
@JoinTable(name="USERPROJECTS" //Tabla de intercambio
, joinColumns={@JoinColumn(name="IDPROJECT") //Llave foránea
}
, inverseJoinColumns={@JoinColumn(name="IDUSER") //Llave foránea
})
@Where( clause = "DELETIONDATE is null" )
private List<PacoUser> users;

我需要创建一个条件来获取一些用户，其中一个条件是用户参与一个或多个项目（这是一个搜索过滤器，因此将来会动态添加这些限制）。这就是我尝试的方式：

Criteria criteria = session.createCriteria(User.class);
criteria.add(Restrictions.isNull(COLUMN_DELETIONDATE));

criteria.add(Restrictions. ......);

....

criteria.add(Restrictions.in("projects", (List<Project>)projects));

和项目包含应该在IN clausule中的项目。

但我成了下一个SQLException：

org.hibernate.exception.GenericJDBCException

Falta el parámetro IN o OUT en el índice:: 1 -- that means : In or OUT parameter are missing in index 1.

任何洞察力？有人能帮我吗？我做错了什么？

非常感谢你提前!!!

好的@frictionlesspulley！我没有意识到:-P。而且再次帮助我，你的回答让我朝着正确的方向前进。正确的方法是

标准条件= session.createCriteria（User.class）; criteria.add（Restrictions.isNull（COLUMN_DELETIONDATE））;

criteria.add（限制......）;

...

criteria.createCriteria（“projects”，Criteria.INNER_JOIN）.add（Restrictions.in（“id”，ids））;

将“ids”作为带有项目ID的Long []

@ManyToMany关系的Hibernate Criteria
