Question

我想创建一个用于在MySQL中保存帐户的Web服务：

package didList;

import javax.jws.WebService;

@WebService
public class Accounts {

public Integer addAccount(String fullName, String username, String password, Boolean isAdmin , Boolean isShowInList){
    Taccount person = new Taccount (fullName,username,password,isAdmin , isShowInList);
    System.out.println("test1");
    AccountManager SVTDB = new AccountManager();
    System.out.println("test2");
    return SVTDB.addAccount(person);
  }
}

它在此行之前打印“test1”：

AccountManager SVTDB = new AccountManager();

但它不打印“test2”，因此该行有问题，

package didList;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class AccountManager {
    private static SessionFactory factory;

    public AccountManager() {
        try {
            NewHibernateUtil.initConnection();
            factory = NewHibernateUtil.getSessionFactory();
        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);

        }
}

public Integer addAccount(Taccount acc) {
    Session session = factory.openSession();
    Transaction tx = null;
    Integer accID = null;
    try {
        tx = session.beginTransaction();
        accID = (Integer) session.save(acc);
        tx.commit();
    } catch (HibernateException e) {
        if (tx != null) {
            tx.rollback();
        }
    } finally {
        session.close();
    }
    return accID;
 }
}

这是NewHibernateUtil类：

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class NewHibernateUtil {

private static SessionFactory sessionFactory;

public static void initConnection() {
    try {
        sessionFactory = createSessionFactory();
    } catch (Throwable ex) {
        // Log the exception. 
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }

}

private static SessionFactory createSessionFactory() {
    Configuration config = new Configuration();
    config.configure("hibernate.cfg.xml");
    return config.buildSessionFactory();
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
}

这是我看到的例外情况：

将hibernate jar文件添加到项目的类路径中。

If you are using eclipse or netbeans simply add the jar file from 
hibernate/lib/required folder into build path of the IDE.
If you are not using any IDE any go to advance system setting and set 
classpath of all jar files.

别忘了将hibernate库放在lib文件夹中。

尝试保存在MySQL DataBase
