解决方案
解决方案二：
packagedb.imp;importjava.util.List;importorg.hibernate.Query;importorg.springframework.orm.hibernate3.support.HibernateDaoSupport;importpojo.CheckType;importpojo.UsersInfo;importdb.dao.userDAO;publicclassuserDAOImplextendsHibernateDaoSupportimplementsuserDAO{publicvoidadd(UsersInfouser){this.getHibernateTemplate().save(user);}publicvoiddel(UsersInfouser){//TODOAuto-generatedmethodstub}publicUsersInfoget(Stringid){UsersInfouser=(UsersInfo)this.getHibernateTemplate().get(UsersInfo.class,id);returnuser;}publicUsersInfologin(StringuserName,StringuserPassword){Stringhql="fromUsersInfowhereuserName=?anduserPwd=?";Queryquery=this.getSession().createQuery(hql);query.setString(0,userName);query.setString(1,userPassword);UsersInfouser=(UsersInfo)query.uniqueResult();returnuser;}publicList<UsersInfo>search(){//TODOAuto-generatedmethodstubreturnnull;}publicvoidupdate(UsersInfouser){}
解决方案三：
兄弟，你撒问题哦？？？
解决方案四：
就是我这样配有错吗?为什么会报我错Exceptioninthread"main"java.lang.NullPointerExceptionatorg.springframework.orm.hibernate3.support.HibernateDaoSupport.getSession(HibernateDaoSupport.java:140)atdb.imp.userDAOImpl.login(userDAOImpl.java:31)atdb.imp.userDAOImpl.main(userDAOImpl.java:52)
解决方案五：
谁能帮帮我?
解决方案六：
学习
解决方案七：
Queryquery=this.getSession().createQuery(hql);获取不到session
