我有一个Dao是：System.out.println("*************begin**");
Criteria dc = sessionFactory.getCurrentSession().createCriteria(MachineSalesReport.class,"mr")
.createAlias("mr.installationInformation", "install").createAlias("mr.customerInformation","customer").createAlias("mr.internalInformation", "internal");
dc.setMaxResults(1);
List<MachineSalesReport> reports= dc.list();
System.out.println("*************end**");
并运行dao，我的控件显示sql有3个sql：

为什么sql这么多？我想要第一个sql，并获取MachineSalesReport，包括customerInformation和InternalInformation以及InstallInformation
