Hibernate的参数类型（集合和数组）

阅读更多

（1）关于以集合为参数的使用
注意“setParameterList("organizations", organizations)” organizations为一个集合

java 代码

Collection organizations;

String queryString = "select distinct (e) from RetiredEmployee as e "
+ "where e.masterPost.organization in (:organizations) " + sortInfo.toString();
Query query = session.createQuery(queryString).setParameterList("organizations", organizations);

 

（2）关于以数组为参数的使用
本HQL语句中有4个参数
所以构造长度为4 的Object[] params 的对象参数

java 代码

public Collection findEmployeesForRetirement(int maleAge, int femaleAge,
            int beforeMonth)
    {
String queryString = "select distinct e from Employee e where "  + "(e.sex = ? and e.birthday < ?) or (e.sex = ? and e.birthday < ?)";
  Object[] params = new Object[] {     new Integer(Employee.SEX_MALE),     maleBirthDay.getTime(),      new Integer(Employee.SEX_FEMALE),     femaleBirthDay.getTime() };   return getHibernateTemplate().find(queryString, params);
    }
