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：

 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.lang.reflect.ParameterizedType;
 import java.util.Collection;
 import java.util.List;

 import org.apache.commons.logging.Log;
 import org.apache.commons.logging.LogFactory;
 import org.hibernate.LockMode;
 import org.springframework.dao.DataAccessException;
 import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

 @SuppressWarnings("unchecked")
 public class GenericDao<T, ID extends Serializable> extends HibernateDaoSupport implements IGenericDao<T, ID> {
     private Log logger = LogFactory.getLog(getClass());

     protected Class<T> entityClass;

     public GenericDao() {

     }

     protected Class getEntityClass() {
         if (entityClass == null) {
             entityClass = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
             logger.debug("T class = " + entityClass.getName());
         }
         return entityClass;
     }

     public void saveOrUpdate(T t) throws DataAccessException {
         this.getHibernateTemplate().saveOrUpdate(t);
     }

     public T load(ID id) throws DataAccessException {
         T load = (T) getHibernateTemplate().load(getEntityClass(), id);
         return load;
     }

     public T get(ID id) throws DataAccessException {
         T load = (T) getHibernateTemplate().get(getEntityClass(), id);
         return load;
     }

     public boolean contains(T t) throws DataAccessException {
         return getHibernateTemplate().contains(t);
     }

     public void delete(T t, LockMode lockMode) throws DataAccessException {
         getHibernateTemplate().delete(t, lockMode);
     }

     public void delete(T t) throws DataAccessException {
         getHibernateTemplate().delete(t);
     }

     public void deleteAll(Collection<T> entities) throws DataAccessException {
         getHibernateTemplate().deleteAll(entities);
     }

     public List<T> find(String queryString, Object value) throws DataAccessException {
         List<T> find = (List<T>) getHibernateTemplate().find(queryString, value);
         return find;
     }

     public List<T> find(String queryString, Object[] values) throws DataAccessException {
         List<T> find = (List<T>) getHibernateTemplate().find(queryString, values);
         return find;
     }

     public List<T> find(String queryString) throws DataAccessException {
         return (List<T>) getHibernateTemplate().find(queryString);
     }

     public void refresh(T t, LockMode lockMode) throws DataAccessException {
         getHibernateTemplate().refresh(t, lockMode);
     }

     public void refresh(T t) throws DataAccessException {
         getHibernateTemplate().refresh(t);
     }

     public Serializable save(T t) throws DataAccessException {
         return getHibernateTemplate().save(t);
     }

     public void saveOrUpdateAll(Collection<T> entities) throws DataAccessException {
         getHibernateTemplate().saveOrUpdateAll(entities);
     }

     public void update(T t, LockMode lockMode) throws DataAccessException {
         getHibernateTemplate().update(t, lockMode);
     }

     public void update(T t) throws DataAccessException {
         getHibernateTemplate().update(t);
     }

     public List<T> list() throws DataAccessException {
         return getHibernateTemplate().loadAll(getEntityClass());

     }

     public List<T> findByNamedQuery(String queryName) throws DataAccessException {
         return getHibernateTemplate().findByNamedQuery(queryName);
     }

     public List<T> findByNamedQuery(String queryName, Object value) throws DataAccessException {
         return getHibernateTemplate().findByNamedQuery(queryName, value);
     }

     public List<T> findByNamedQuery(String queryName, Object[] values) throws DataAccessException {
         return getHibernateTemplate().findByNamedQuery(queryName, values);
     }

 }

怎么使用，自行补脑吧
