休眠对象和Java反射

Question

I am lazily loading an object from hibernate using the following line of code Object object = session.load(Class.forName(javaType), objectId);

If I print object.getClass().getSimpleName() it displays the name of the hibernate proxy and not my implementation class as expected.

However If I then use reflection on this proxy object to return an attribute called children as follows: List children = (List) object.getClass().getMethod("getChildren", new Class[ {}).invoke(object, new Object[]{});

It is returning a list of objects where object.getClass().getSimpleName() on any of the objects returns the implementation class name. Why are these objects not returning the proxy object name?

Answer 1

列表本身可以延迟加载，但是如果枚举元素，则需要执行sql查询，并且为每个元素创建代理都不会提高性能（相反）。
