Ø Layout
ª layout通过外键继承与localizable，由于设置了非延迟加载，检索layout时，Hibernate会通过外键关联(内连接)同时检索出子表（layout）和父表（localizable）
©查找Layout对象
Layout
layout = layoutManager.findLayoutByDefinition(tmpDefinition);
return (Layout) findUniqueResult("from Layout l where l.definition = ?", new
Object[]{definitionName});
© HQL语句
