整合hibernate4到spring4mvc框架
1.总体设计思路
写一个HibernateDao的公共接口HibernateCommonDao，实现基本的增删改查HibernateCommonDaoImpl，所有的具体业务类*DaoImpl都继承自HibernateCommonDaoImpl并且implements它自己的*Dao接口，这样一来基本的增删改查都用公共的，只针对具体业务实现自己的接口方法，业务类Service调用query对象方法的时候需要进行强制类型转换
2.springmvc管理hibernate的配置问题
2.1pom.xml配置仍然是http://my.oschina.net/u/555061/blog/506049，只不过增加Spring4Framework框架
2.2SpringHibernate4.xml--解决sessionFactory注册为SpringBean
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan">
<list>
<value>com.zhxjz.model.hibernateEmployee</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="dialect">${hibernate.dialect}</prop>
<prop key="show_sql">${hibernate.show_sql}</prop>
<!-- <prop key="hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> -->
</props>
</property>
</bean>
<!-- 配置Hibernate事务管理器（由于在SpringDatasource.xml已经配置了事务，因此这里不能再次配置）
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean> -->
</beans>
2.3 SpringDatasource.xml事务管理配置如下，这个事务管理对Hibernate的SessionFactory事务生效，同时对JdbcTemplate的事务管理生效
2.4 关于事务管理
需要在*ServiceImpl添加注解@Transactional，然后测试事务生效过程，
public void add(Object newObj) {
Session session = getCurrentSession();
session.save(newObj);
SQLQuery query = getCurrentSession().createSQLQuery(
"update hibernateemployee set employeeId=2 where uuid='uuid2'");
query.executeUpdate();
}
这个sqlquery就是用来测试回滚的，修改主键违反主键唯一性原则导致update操作失败，测试是否先进行的save插入操作是否成功，结果是不成功，证明事务生效。
2.5 hibernate.properties，这里的含义可以参考http://my.oschina.net/u/555061/blog/506049
hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.show_sql=true #hibernate.hbm2ddl.auto=create
3.公共Dao/DaoImpl结构如下，
这里HibernateEmployeeDao/HibernateEmployeeDaoImpl是具体业务，HibernateCommonDao和HibernateCommonDaoImpl是公共接口方法（也就是增删改查ORM实现）
4.给出类源码
4.1HibernateCommonDao.java
package com.zhxjz.dao;
import java.util.List;
public interface HibernateCommonDao {
public void add(Object newObj);
public void del(Class<?> clazz, int id);
public void update(Object updObj);
public Object queryById(Class<?> clazz, int id);
public List queryList(String sql);
}
4.2HibernateCommonDaoImpl.java
package com.zhxjz.dao.impl;
import java.util.List;
import org.hibernate.SQLQuery;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.zhxjz.dao.HibernateCommonDao;
@Component
public class HibernateCommonDaoImpl implements HibernateCommonDao {
@Autowired
private SessionFactory sessionFactory;
@Override
public void add(Object newObj) {
Session session = getCurrentSession();
session.save(newObj);
SQLQuery query = getCurrentSession().createSQLQuery(
"update hibernateemployee set employeeId=2 where uuid='uuid2'");
query.executeUpdate();
}
@Override
public void del(Class<?> clazz, int id) {
Session session = getCurrentSession();
Object delObj = session.get(clazz, id);
session.delete(delObj);
}
@Override
public void update(Object updObj) {
getCurrentSession().update(updObj);
}
@Override
public Object queryById(Class<?> clazz, int id) {
return getCurrentSession().get(clazz, id);
}
@Override
public List queryList(String sql) {
SQLQuery query = getCurrentSession().createSQLQuery(sql);
return query.list();
}
protected Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
}
4.3HibernateEmployeeDao.java
package com.zhxjz.dao.hibernateEmployee;
import com.zhxjz.dao.HibernateCommonDao;
public interface HibernateEmployeeDao extends HibernateCommonDao {
public void ownBusiness();
}
4.4HibernateEmployeeDaoImpl.java
package com.zhxjz.dao.hibernateEmployee.impl;
import org.springframework.stereotype.Repository;
import com.zhxjz.dao.hibernateEmployee.HibernateEmployeeDao;
import com.zhxjz.dao.impl.HibernateCommonDaoImpl;
@Repository("hibernateEmployeeDao")
public class HibernateEmployeeDaoImpl extends HibernateCommonDaoImpl implements
HibernateEmployeeDao {
@Override
public void ownBusiness() {
}
}
4.5HibernateEmployeeService.java
package com.zhxjz.service.hibernateEmployee;
import java.util.List;
import com.zhxjz.model.hibernateEmployee.HibernateEmployee;
public interface HibernateEmployeeService {
public void add(HibernateEmployee hibernateEmployee);
public void del(int id);
public void update(HibernateEmployee updObj);
public HibernateEmployee queryById(int id);
public List<HibernateEmployee> queryList(String sql);
}
4.6HibernateEmployeeServiceImpl.java
package com.zhxjz.service.hibernateEmployee.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.zhxjz.dao.hibernateEmployee.HibernateEmployeeDao;
import com.zhxjz.model.hibernateEmployee.HibernateEmployee;
import com.zhxjz.service.hibernateEmployee.HibernateEmployeeService;
@Service
@Transactional
public class HibernateEmployeeServiceImpl implements HibernateEmployeeService {
@Autowired
private HibernateEmployeeDao hibernateEmployeeDao;
@Override
public void add(HibernateEmployee hibernateEmployee) {
hibernateEmployeeDao.add(hibernateEmployee);
}
@Override
public void del(int id) {
hibernateEmployeeDao.del(HibernateEmployee.class, id);
}
@Override
public void update(HibernateEmployee hibernateEmployee) {
hibernateEmployeeDao.update(hibernateEmployee);
}
@Override
public HibernateEmployee queryById(int id) {
return (HibernateEmployee) hibernateEmployeeDao.queryById(
HibernateEmployee.class, id);
}
@SuppressWarnings("unchecked")
@Override
public List<HibernateEmployee> queryList(String sql) {
return hibernateEmployeeDao.queryList(sql);
}
}
4.7model类--HibernateEmployee.java
package com.zhxjz.model.hibernateEmployee;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "HIBERNATEEMPLOYEE")
public class HibernateEmployee {
private String uuid;
@Id
@Column(name = "EMPLOYEEID")
private int employeeId;
private String employeeName;
private boolean isOnjob;
public HibernateEmployee() {
}
public HibernateEmployee(String uuid, int employeeId, String employeeName, boolean isOnjob) {
this.uuid = uuid;
this.employeeId = employeeId;
this.employeeName = employeeName;
this.isOnjob = isOnjob;
}
省略getter和setter。。。
}
4.8HibernateEmployeeController.java
package com.zhxjz.controller.hibernateEmployee;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import com.zhxjz.framework.model.json.JsonResult;

import com.zhxjz.service.hibernateEmployee.HibernateEmployeeService;
@Controller
@RequestMapping("/hibernateemployee")
public class HibernateEmployeeController {
@Autowired
HibernateEmployeeService hibernateEmployeeService;
@RequestMapping("/add.do")
public String add(HibernateEmployee hibernateEmployee, ModelMap model) {
hibernateEmployee.setUuid("uuid1");
hibernateEmployeeService.add(hibernateEmployee);
String message = new JsonResult().toJson();
model.put("message", message);
return "message";
}
@RequestMapping("/del.do")
public String del(int employeeId, ModelMap model) {
hibernateEmployeeService.del(employeeId);
String message = new JsonResult().toJson();
model.put("message", message);
return "message";
}
@RequestMapping("/update.do")
public String update(int employeeId, String field, Object value,
ModelMap model) {
Map<String, Object> updInfo = new HashMap<String, Object>();
updInfo.put(field, value);
HibernateEmployee hibernateEmployee = new HibernateEmployee("uuid2", employeeId, "testemployee2", false);
hibernateEmployeeService.update(hibernateEmployee);
String message = new JsonResult().toJson();
model.put("message", message);
return "message";
}
@RequestMapping("/queryOne.do")
public String queryOne(int employeeId, ModelMap model) {
HibernateEmployee obj = (HibernateEmployee) hibernateEmployeeService
.queryById(employeeId);
String message = new JsonResult(obj).toJson();
model.put("message", message);
return "message";
}
@RequestMapping("/querylist.do")
public String querylist(ModelMap model) {
String sql = "select * from hibernateemployee limit 0,2";
List<HibernateEmployee> employeeList = hibernateEmployeeService.queryList(sql);
String message = new JsonResult(employeeList).toJson();
model.put("message", message);
return "message";
}
}
