hibernate的lazy加载，为什么控制台都打印出来加载完成，而又取不到呢？

信息台打印信息如下：
1 collections were found in result set for role: com.xy.po.Test.testsubs

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@0------------------------------------------------------
test与testsub一对多的关系;List list = testBo.queryTest();
Test test = (Test)list.get(0);//此条test有对应的2条testsub
Set testSet = test.getTestsubs();
System.out.println("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@"+testSet.size());
为什么打印出来的结果是0？
我用的是openSessionInView
