Hibernate中使用DetachedCriteria进行多字段条件查询（之间关系为or）的有关问题

Hibernate中使用DetachedCriteria进行多字段条件查询（之间关系为or）的问题
如主旨，DetachedCriteria查询条件对象Restrictions.or(lhs,rhs);只能假如两个参数，但是我的查询条件有14个，而且之间都是or的关系，那么该如何写呢？ 
我自己尝试用嵌套来写，可是tomcat报错，具体代码如下： 

Java code

//创建查询对象detachedCriteria        DetachedCriteria detachedCriteria = DetachedCriteria.forClass(CmNetPlan.class);                detachedCriteria.add(Restrictions.or(Restrictions.or(Restrictions.or(Restrictions.or(Restrictions.or(Restrictions.or(                Restrictions.eq("monAm", monAm),                 Restrictions.eq("monPm", monPm)),                 Restrictions.or(                        Restrictions.eq("tuesAm", tuesAm),                         Restrictions.eq("tuesPm", tuesPm))),                        Restrictions.or(Restrictions.or(                                Restrictions.eq("wedAm", wedAm),                                 Restrictions.eq("wedPm", wedPm)),                                 Restrictions.or(                                        Restrictions.eq("thursAm", thursAm),                                         Restrictions.eq("thursPm", thursPm)))),                                        Restrictions.or(Restrictions.or(                                                Restrictions.eq("friAm", friAm),                                                Restrictions.eq("friPm", friPm)),                                                Restrictions.or(                                                        Restrictions.eq("satAm", satAm),                                                         Restrictions.eq("satPm", satPm)))),                                                        Restrictions.or(                                                                Restrictions.eq("sunAm", sunAm),                                                                 Restrictions.eq("sunPm", sunPm))), null));
