我想用spring 3 mvc的hibernate,但是现在我得到这个异常抛出。我想我需要在某处定义我的hibernate.cfg.xml
,但不知道在哪里?org.hibernate.HibernateException:/hibernate.cfg.xml找不到
我基本上遵循这个例子在这里http://www.nabeelalimemon.com/blog/2010/05/spring-3-integrated-with-hibernate-part-a/在特别看到这行代码那里,想为“神奇”利用找到我hibernate.cfg文件这样的:
return new Configuration().configure().buildSessionFactory();
我猜测是不正确的?目前,我有我的hibernate.cfg文件中src/com/jr/hibernate/
是我的CFG文件:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

</session-factory>
</hibernate-configuration>
我休眠utils的类:
package com.jr.utils;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtils {
private static final SessionFactory sessionFactory = buildSessionFactory();
public static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
return new Configuration().configure().buildSessionFactory();
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
}
都会调用BU这个抽象类:
package com.jr.db;
import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;
import com.jr.utils.HibernateUtils;
public abstract class DbWrapper<T> {
private static SessionFactory sessionFactory = null;
private static Session session;
public DbWrapper() {
setSessionFactory();
}
private void setSessionFactory() {
sessionFactory = HibernateUtils.buildSessionFactory();
session = sessionFactory.getCurrentSession();
}
public boolean addNewItem(T dbItem) {
try {
session.getTransaction().begin();
session.save(dbItem);
session.getTransaction().commit();
} catch (Exception e) {
System.err.println("error exception when adding new item to table"
+ e);
} finally {
session.close();
sessionFactory.close();
}
return false;
}
public abstract boolean removeItem(String uid);
public abstract boolean modifyItem(String uid, T item);
}
这里是最初做一些休眠的控制器东西:
private Logger logger = Logger.getLogger(UserController.class);
private UserDb userDb;
@RequestMapping(value = "/user/registerSuccess", method = RequestMethod.POST)
public String submitRegisterForm(@Valid User user, BindingResult result) {
// validate the data recieved from user
logger.info("validate the data recieved from user");
if (result.hasErrors()) {
logger.info("form has "+result.getErrorCount()+" errors");
return "account/createForm";
} else{
// if everthings ok, add user details to database
logger.info("if everthings ok, add user details to database");
userDb = new UserDb();
userDb.addNewItem(user);
// display success and auto log the user to the system.
return "account/main";
}
}
提前干杯。我也在我的hibernate.cfg.xml文件所在的位置拥有我所有的表hibvernate xml映射
欢呼声。有用。我有另一个问题。我的应用程序似乎无法找到我的hibernate xml映射。我把它放在com.jr.hibernateMappings中,但是build.xml似乎并没有构建和编译我的hbm.xml文件。它又是在错误的位置吗?它是否需要在WAR/WEB-INF/classes文件夹中?如果可能的话,我更愿意将它放在src目录中 – jonney
谢谢...在将我的文件(hibernate.cfg.xml)移动到src后,它会再次找到文件,非常感谢 –
