我有一些休眠查询,我期望一些对象被快速加载,而另一些则是延迟加载。 我目前正在检查急切加载的方法是测量访问属性所用的时间。如何以编程方式检查懒惰/渴望加载
//Call the method i want to test.
Customer customer = loadCustomerWithProducts();
long start = System.currentTimeMillis();
//Call a method on an object that sould have been eagerly loaded.
customer.getProducts().get(0).getName();
long end = System.currentTimeMillis();
long diff = end - start;
Assert.assertTrue(diff < 50); //Assuming that hitting the database takes longer than 50ms.
这个问题很有缺陷,因为测试会因系统性能而失败。有没有更好的办法?
