在配置SSH时出现java.lang.reflect.InvocationTargetException

Question

求救，这个问题折腾我好几天了；
我加了抽象的Dao层，实体层，biz层之后就出现这样的错误了，能正常调用Dao层的方法，但是它貌似不能自动关闭Session的原因导至。希望高手帮我瞧瞧》。。我的分不是太多了，所以还望海涵...java.lang.reflect.InvocationTargetException

Answer 1

内存溢出！是你所说的session没有关闭的原因，但你没有贴出代码我们怎么看得出哪段代码出问题，你是不是使用了spring的getSession()去操作，如果是这样 的话session要手动关闭的，如果是使用getHibernateTemplate();则不需要手动去关闭
