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。
