HibernateDaoSupport的使用

1、HibernateDaoSupport是有spring提供的一个hibernate模版工具类，或不多说，直接上代码

     接口 IGenericDao.java

package org.hibernatetemplate.test;

/**
 * 功能：hibernate  操作 模板基类设计
 * @author geenkDC
 * @version 1.0  2016-01-04 17:01:42
 * @JDK 7
 */
import java.io.Serializable;
import java.util.Collection;
import java.util.List;

import org.hibernate.LockMode;
import org.springframework.dao.DataAccessException;


public interface IGenericDao<T, ID extends Serializable> {

    public T load(ID id) throws DataAccessException;

    public T get(ID id) throws DataAccessException;

    public boolean contains(T t) throws DataAccessException;

    public void refresh(T t, LockMode lockMode) throws DataAccessException;

    public void refresh(T t) throws DataAccessException;

    public Serializable save(T t) throws DataAccessException;

    public void saveOrUpdate(T t) throws DataAccessException;

    public void saveOrUpdateAll(Collection<T> entities) throws DataAccessException;

    public void update(T t, LockMode lockMode) throws DataAccessException;

    public void update(T t) throws DataAccessException;

    public void delete(T t, LockMode lockMode) throws DataAccessException;

    public void delete(T t) throws DataAccessException;

    public void deleteAll(Collection<T> entities) throws DataAccessException;

    public List<T> find(String queryString, Object value) throws DataAccessException;

    public List<T> find(String queryString, Object[] values) throws DataAccessException;

    public List<T> find(String queryString) throws DataAccessException;

    public List<T> list() throws DataAccessException;

    public List<T> findByNamedQuery(String queryName) throws DataAccessException;

    public List<T> findByNamedQuery(String queryName, Object value) throws DataAccessException;

    public List<T> findByNamedQuery(String queryName, Object[] values) throws DataAccessException;


}

      接口实现类：

  1 package org.hibernatetemplate.test;

  3 /**
  4  * 功能：hibernate  操作 模板基类设计

怎么使用，自行补脑吧
