跪求大神解决！在整合struts2框架和hibernate框架时，在action类中连接数据库失败

qq_30071905 2017-08-10 02:19:31
事情是这样的，就是写了一个简单的登录注册功能。用test方法测试均没有错误，但是只要一在action类中就无法运行！
代码如下：
HibernateUtil工具类



public class HibernateUtil {

	private static SessionFactory sessionfactory;

	static{

		Configuration cfg=new Configuration().configure();

		sessionfactory=cfg.buildSessionFactory();

	}

	public static SessionFactory getSessionfactory() {

		return sessionfactory;

	}

	public static Session getSession(){

		return sessionfactory.openSession();

	}

}

登录验证类
[code=java
]public class UserLoginDaoImpl implements UserLoginDao {
public boolean login(UserLoginBean ulb) {
Session s=HibernateUtil.getSession();
try {
String sql = "select * from user where username=?and password=?";
Query query = s.createSQLQuery(sql);
query.setParameter(0, ulb.getUsername());
query.setParameter(1, ulb.getPassword());
List list = query.list();
if (!list.isEmpty())
{
System.out.println("登录成功？");
return true;
}
else{
System.out.println("登录失败");
return false;
}
} catch (Exception e) {
e.printStackTrace();
}finally{
if(s!=null)
if(s.isOpen()){
s.close();
}
}
return false;
}
}
}[/code]
登录验证的action类如下：


public class LoginAction extends ActionSupport {

	private String username;

	private String password;

	private String Error;

	public String execute() throws Exception {

		UserLoginDao dao=new UserLoginDaoImpl();

		UserLoginBean userlogin=new UserLoginBean();

		userlogin.setUsername(username);

		userlogin.setPassword(password);

		System.out.println(userlogin.getUsername());

		System.out.println(userlogin.getPassword());

		System.out.println("执行之前");

		boolean b=dao.login(userlogin);

		System.out.println();

		System.out.println("执行之后");

		if(b==true){

			return "success";

		}else{

			this.setError("账户名或用户密码错误！");

			return "error";

		}

	}

	public String getUsername() {

		return username;

	}

	public void setUsername(String username) {

		this.username = username;

	}

	public String getPassword() {

		return password;

	}

	public void setPassword(String password) {

		this.password = password;

	}

	public String getError() {

		return Error;

	}

	public void setError(String error) {

		Error = error;

	}

	

}

问题就是，登录验证类用junit测试均能正常运行，也可以连接到数据库。
但是在action类里面只要有连接到数据库的操作，都会报错。

执行之后


跳转都是正常的，也能拿到jsp的参数，数据库连接也是对的，在junit测试中就可以连接到数据库并且实施操作，但是只要在action类中有任何连接数据库的操作，都会报上述的错误，不知道为什么，求大神解答！

导入的jar包如下

问题已解决，配置文件什么的确实没有问题，mysql的jdbc驱动，我在tomcat的lib文件夹放了一份，在\java\jdk\jre\lib\ext中也放了一份。还是不起作用。最后把驱动放在\java\jre\lib\ext里面就可以正常连接数据库了。 不仅仅要求将驱动加入classpath中，而且需要将该jar包加入到Java运行环境的外部jar包中！
我靠，老哥，真的好了！！！！ 不知道为啥是这个原因，为什么是需要这样呀？ 我到如别人的工程都没这样也行，估计还是代码哪里没写好。。。。

对了，错误代码限于篇幅没有截完整，说是找不到数据库连接驱动！但是我不在action类中，是可以连接到数据库的，把action中的代码原封不动放在另一个类中，是完全可以运行的，但是一到action中就无法连接到数据库！
