Question

我发现异常： - [java.lang.NoSuchMethodError：org.hibernate.internal.CoreMessageLogger.debugf（Ljava / lang / String; I）V] 同时调用buildsessionfactory方法。对于这个例外，我还没有能够连接数据库（mysql）。这是我的代码： - 行动档案： - EmpAction.java： -

＆＃13;

package techmyguru.actions;



import com.opensymphony.xwork2.ActionSupport;
//import com.opensymphony.xwork2.ModelDriven;
//import com.opensymphony.xwork2.Preparable;

public class EmpAction extends ActionSupport {
	//Employee emp;
	private int id;
	private String password;
	private String name;
	private String email;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
    public String execute()
	{
		try{
			int i=EmpDao.register(this);
			if(i==1)
			{
			return "success";
			}
			else
			{
				return "error";
			}
		}
		catch(Throwable t)
		{
			t.toString();
			return "fail";
		}
	}  
}

＆＃13;

＆＃13; 这是我的数据库连接文件： -

＆＃13;

package techmyguru.actions;

//import java.util.List;

//import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class EmpDao {
	

	public static int  register(EmpAction e) {
		int i=0;
		Configuration c=null;
		SessionFactory sf=null;
		Session session=null;
		Transaction tr=null;
		try
		{
			try
			{
		c=new Configuration().configure("hibernate.cfg.xml");
			}catch(Throwable t)
			{
				System.out.println("configuration problem");
				t.printStackTrace();
			}
			try{
		sf = c.buildSessionFactory();
			}catch(Throwable t)
			{
				System.out.println("sessionfactory problem");
				t.printStackTrace();
			}
			try{
		session=sf.openSession();
			}catch(Throwable t)
			{
				System.out.println("session opening problem");
				t.printStackTrace();
			}
			try{
		tr=session.beginTransaction();
			}catch(Throwable t)
			{
				System.out.println("transaction opening problem");
				t.printStackTrace();
			}
			try{
		tr.begin();
			}catch(Throwable t)
			{
				System.out.println("transaction begining problem");
				t.printStackTrace();
			}
			try{
		i=(Integer)session.save(e);
			}catch(Throwable t)
			{
				System.out.println("transaction saving problem");
				t.printStackTrace();
			}
			try{
		tr.commit();
			}catch(Throwable t)
			{
				System.out.println("transaction commiting problem");
				t.printStackTrace();
			}
		session.close();
		return i;
		}
		catch(Throwable t)
		{
			t.toString();
			return i;
		}
	}
	
		
	
}

＆＃13;

＆＃13; 我在这个项目中使用了maven。

错误在以下行给出：

＆＃13;

SessionFactory sf = c.buildSessionFactory();

＆＃13;

＆＃13; 在数据库连接文件EmpDao.java中。

Answer 1

这是正常工作的代码你可以试试。

    private static SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;
    Configuration configuration = new Configuration();
    configuration.configure("hibernate.cfg.xml");

    serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    Session session = sessionFactory.openSession();
    session.beginTransaction();
    // process your business logic.
    session.getTransaction().commit();

在调用buildsessionfactory方法时发现Hibernate异常
