userDaoImpl.java
package com.hello.hellospring.dao;
import org.hibernate.Criteria;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Repository;
import com.hello.hellospring.model.User;
@Repository("userDao")
public class UserDaoImpl extends AbstractDao<Integer, User> implements UserDao {
public void save(User user) {
persist(user);
}
public User findById(int id) {
return getByKey(id);
}
public User findBySSO(String sso) {
Criteria crit = createEntityCriteria();
crit.add(Restrictions.eq("ssoId", sso));
return (User) crit.uniqueResult();
}
}
這裏是我得到的錯誤類：
AbstractDao.java
package com.hello.hellospring.dao;
import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;
public abstract class AbstractDao<PK extends Serializable, T> {
private final Class<T> persistentClass;
@SuppressWarnings("unchecked")
public AbstractDao(){
this.persistentClass =(Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass()).getActualTypeArguments()[1];
}
@Autowired
private SessionFactory sessionFactory;
@Transactional
protected Session getSession(){
return sessionFactory.getCurrentSession();
}
@SuppressWarnings("unchecked")
public T getByKey(PK key) {
return (T) getSession().get(persistentClass, key);
}
public void persist(T entity) {
getSession().persist(entity);
}
public void delete(T entity) {
getSession().delete(entity);
}
protected Criteria createEntityCriteria(){
return getSession().createCriteria(persistentClass);
}
}
我不知道什麼是錯，我得到的問題是：請幫我解決這個問題。每次我運行這段代碼時，都會說我有一些休眠會話問題。謝謝:)
嗨我有一些問題與通用道這是什麼解決方案？ –
