mybatis3.2.8 与 hibernate4.3.6 混用
混用是混合在一起使用,可以复用公共的配置。例如
a) mybatis与hibernate的sessionFactory，共用同一个dataSource
b) 事务管理共用hibernate的事务管理。
而不是使用mybatis和hibernate两个配置文件,使用mybatis就使用mybatis的配置文件里的配置,使用hibernate时就使用hibernate对应的配置。

mybatis、hibernate这二个框架各有特色，对于复杂的查询，利用mybatis直接手写sql控制起来更灵活，而一般的insert/update，hibernate比较方便。同一个项目中，这二个框架可以和谐共存，下面是一些步骤：
一、版本要求
Spring 4.11 + hibernate 4.3.6 + mybatis 3.2.8 + struts 2.3.16.3 (这是目前各框架的最新版本)
建议：如果用hibernate 4.x ，Spring最好也是4.x系列，否则getCurrentSession()容易报错。

三、Spring配置（关键）
com.cnblogs.yjmyzz.entity
classpath*:hibernate/**/*.hbm.xml
org.hibernate.dialect.Oracle10gDialect
false
true
true
3
20
20
false
有几个关键点：
a) mybatis与hibernate的sessionFactory，共用同一个dataSource
b) 事务管理共用hibernate的事务管理
四、web.xml配置
struts2-app-sample
org.apache.logging.log4j.web.Log4jServletContextListener
log4jServletFilter
org.apache.logging.log4j.web.Log4jServletFilter
log4jServletFilter
/*
REQUEST
FORWARD
INCLUDE
ERROR
contextConfigLocation
classpath:spring.xml
org.springframework.web.context.ContextLoaderListener
struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
loggerFactory
com.opensymphony.xwork2.util.logging.slf4j.Slf4jLoggerFactory
openSessionInViewFilter
org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
singleSession
true
struts2
/*
index.html
五、代码调用
5.1 服务层基类
其它各业务服务实现类，都继承自它。当然，也可以弄一个BaseDAO，对hibernate做些封装
package com.cnblogs.yjmyzz.dao;
import java.io.Serializable;
import java.util.List;
/**
* 基础数据库操作类
*
* @author ss
*
*/
public interface BaseDAO {
/**
* 保存一个对象
*
* @param o
* @return
*/
public Serializable save(T o);
/**
* 删除一个对象
*
* @param o
*/
public void delete(T o);
/**
* 更新一个对象
*
* @param o
*/
public void update(T o);
/**
* 保存或更新对象
*
* @param o
*/
public void saveOrUpdate(T o);
/**
* 查询
*
* @param hql
* @return
*/
public List find(String hql);
/**
* 查询集合
*
* @param hql
* @param param
* @return
*/
public List find(String hql, Object[] param);
/**
* 查询集合
*
* @param hql
* @param param
* @return
*/
public List find(String hql, List
package com.cnblogs.yjmyzz.dao.impl;
import com.cnblogs.yjmyzz.dao.BaseDAO;
import java.io.Serializable;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
@Component("baseDAO")
@SuppressWarnings("all")
public class BaseDAOImpl implements BaseDAO {
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
private Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
public Serializable save(T o) {
return this.getCurrentSession().save(o);
}
public void delete(T o) {
this.getCurrentSession().delete(o);
}
public void update(T o) {
this.getCurrentSession().update(o);
}
public void saveOrUpdate(T o) {
this.getCurrentSession().saveOrUpdate(o);
}
public List find(String hql) {
return this.getCurrentSession().createQuery(hql).list();
}
public List find(String hql, Object[] param) {
Query q = this.getCurrentSession().createQuery(hql);
if (param != null && param.length > 0) {
for (int i = 0; i < param.length; i++) {
q.setParameter(i, param[i]);
}
}
return q.list();
}
public List find(String hql, List 至于mybatis，就没必要封装了，因为各xxxMapper接口，注入后可以直接拿来调
5.2 调用示例
package com.cnblogs.yjmyzz.service.support;
import java.math.BigDecimal;
import java.util.*;
import javax.annotation.Resource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.cnblogs.yjmyzz.convertor.OrderConverter;
import com.cnblogs.yjmyzz.dao.BaseDAO;
import com.cnblogs.yjmyzz.dto.Order;
import com.cnblogs.yjmyzz.entity.TOrder;
import com.cnblogs.yjmyzz.mybatis.mapper.OrderMapper;
import com.cnblogs.yjmyzz.service.OrderService;
@Service
public class OrdersServiceImpl extends BaseServiceImpl implements OrderService {
@Autowired
OrderMapper orderMapper;
@Resource
BaseDAO tOrderDAO;
private static final long serialVersionUID = 1513133416493770048L;
@Override
public Order get(String id) {
// hibernate实现
// return OrderConverter.toDto((TOrder) getCurrentSession().get(
// TOrder.class, new BigDecimal(Integer.parseInt(id))));
return OrderConverter.toDto(tOrderDAO.get(TOrder.class, new BigDecimal(
Integer.parseInt(id))));
// mybatis实现
// return
// OrderConverter.toDto(orderMapper.getOrder(Integer.parseInt(id)));
}
@Override
public List getAll() {
List entities = orderMapper.getAllOrder();
List orders = new ArrayList();
for (TOrder entity : entities) {
orders.add(OrderConverter.toDto(entity));
}
return orders;
}
@Override
public void doSave(Order order) {
// hibernate
TOrder entity = OrderConverter.toEntity(order);
if (entity.getId() != null) {
entity = (TOrder) getCurrentSession().get(TOrder.class,
entity.getId());
// update fields
entity.setClientname(order.getClientName());
entity.setAmount(new BigDecimal(order.getAmount()));
}
getCurrentSession().saveOrUpdate(entity);
}
@Override
public void doRemove(String id) {
// mybatis
orderMapper.deleteOrder(Integer.parseInt(id));
}
} 其它注意事项：
hibernate 4.x以后，entity类上的注解，最好改成@Entity("TABLE_NAME")，而非以前的@Table(xxx)，参考：
@Entity(name = "T_ORDER") public class TOrder implements java.io.Serializable {
