springMVC+Hibernate 框架整合

这是一个springmvc+hibernate框架整合的demo，拿出来分享，希望对初学框架的人有所帮助；

开发前的准备工作

1.所需要的jar包，主要有springmvc jar包，hibernate jar包 ，数据库连接驱动包，数据源jar包，等 ；

具体如下：



建立Java web项目

目录结构具体如下：



核心配置文件介绍

1.项目核心入口配置文件（web.xml）：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<!-- Spring应用上下文监听器 -->
<!-- ContextLoaderListener监听器的作用就是启动Web容器时，自动装配ApplicationContext的配置信息。 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 配置spring核心servlet -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet

<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- url-pattern配置为/，不带文件后缀，会造成其它静态文件(js，css等)不能访问。如配为*.do，则不影响静态文件的访问 -->
<servlet-mapping>

</web-app>

2.springmvc配置文件（spring-servlet.xml）：

<?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"

<property name="suffix" value=".jsp" />
</bean>
</beans>

3.spring上下文核心配置文件(applicationContext-core.xml):

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- oracle配置数据源 -->

</property>
<!-- 注解扫描的包 -->

</bean>

<!-- 配置一个事务管理器 -->
<bean id="transactionManager"

<property name="sessionFactory" ref="sessionFactory" />
</bean>

<!-- 配置事务，使用代理的方式 -->
<bean id="transactionProxy"

<prop key="del*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>

</beans>

业务逻辑bean层注册，及spring bean代理文件（applicationContext-beans.xml）：

<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--dao层 bean  -->
<bean id="UserDaoImplTarget" class="com.liu.daoImpl.UserDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<!--service层 bean  -->
<bean id="UserService" class="com.liu.service.UserService">
<property name="UserDaoImpl" ref="UserDaoImplTarget"></property>
</bean>

<!-- 此处为spring 代理  dao层bean-->
<bean name="UserDaoImpl" parent="transactionProxy">
<property name="target" ref="UserDaoImplTarget"></property>
</bean>

</beans>

此实体的定义应用了springmvc的注解，省去了传统的Hibernate跟数据库之间的映射配置文件（User.java）

package com.liu.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;

/**
* 此实体的定义应用了springmvc的注解，省去了传统的Hibernate跟数据库之间的映射配置文件
* @author will
*
*/
@Entity
@Table(name="T_USER")
public class User {

@Id
@GeneratedValue(generator="system-uuid")
@GenericGenerator(name = "system-uuid",strategy="uuid")
@Column(length=100)
private String id;

@Column(length=32)
private String userName;

@Column(length=32)
private String age;

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String getAge() {
return age;
}

public void setAge(String age) {
this.age = age;
}

}

业务逻辑层介绍

1.业务dao层（UserDao.java）：

package com.liu.dao;

import java.util.List;

import com.liu.entity.User;

public interface UserDao {

public User getUser(String id);

public List<User> getAllUser();

public void addUser(User user);

public boolean delUser(String id);

public boolean updateUser(User user);

}

2.业务dao层实现（UserDaoImpl.java）：

package com.liu.daoImpl;

import java.util.List;

import com.liu.dao.UserDao;
import com.liu.entity.User;

import org.hibernate.Criteria;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class UserDaoImpl implements UserDao{

private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
/**
* 根据用户id查询用户
*/
@Override
public User getUser(String id) {
String hql = "from User u where u.id=?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, id);

return (User)query.uniqueResult();
}
/**
* 查询所有用户
*/

@Override
public List<User> getAllUser() {
/* String hql = "select * from t_user";
System.out.print("--------------------->");*/
Criteria crit = sessionFactory.getCurrentSession().createCriteria(User.class);

System.out.print(crit.list().size()+"--------------------->");
return crit.list();
}

/**
* 添加用户
*/

@Override
public void addUser(User user) {
System.out.println("用户名：==impl===="+user.getUserName());
System.out.println("用户名：==impl===="+user.getAge());
Transaction tx = sessionFactory.getCurrentSession().beginTransaction();
sessionFactory.getCurrentSession().save(user);
tx.commit();
sessionFactory.getCurrentSession().flush();
System.out.println("用户名：==add====");
}

/**
* 根据用户id删除用户
*/
@Override
public boolean delUser(String id) {
String hql = "delete User u where u.id = ?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, id);

return (query.executeUpdate() > 0);
}
/**
* 编辑用户
*/
@Override
public boolean updateUser(User user) {
String hql = "update User u set u.userName = ?,u.age=? where u.id = ?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, user.getUserName());
query.setString(1, user.getAge());
query.setString(2, user.getId());

return (query.executeUpdate() > 0);
}

}

业务service层实现（UserService.java）

package com.liu.service;

import java.util.List;

import com.liu.dao.UserDao;
import com.liu.daoImpl.UserDaoImpl;
import com.liu.entity.User;

public class UserService implements UserDao{

private UserDaoImpl userDaoImpl;

public UserDaoImpl getUserDaoImpl() {
return userDaoImpl;
}

public void setUserDaoImpl(UserDaoImpl userDaoImpl) {
this.userDaoImpl = userDaoImpl;
}

@Override
public User getUser(String id) {

return userDaoImpl.getUser(id);
}

@Override
public List<User> getAllUser() {

return userDaoImpl.getAllUser();
}

@Override
public void addUser(User user) {
userDaoImpl.addUser(user);

}

@Override
public boolean delUser(String id) {

return userDaoImpl.delUser(id);
}

@Override
public boolean updateUser(User user) {

return userDaoImpl.updateUser(user);
}

}
