本文探讨了Hibernate中get()与load()方法的不同之处。get()方法在找不到对象时返回null，而load()方法总是返回一个代理对象，如果底层对象不存在，则通过该代理对象抛出ObjectNotFoundException。建议在确定对象存在时使用load()，不确定时使用get()。
Take a look at the Hibernate documentation (though I agree is not very explicit) - the HibernateTemplate is basically a wrapper around the native Hibernate API.
get() will return null if an object is not found while load() will always return a non-null object which is a proxy. If the underlying object does not exist, the proxy will thrown ObjectNotFoundException.
load() should be used when you are sure that the object exits while get() when you're not.
