spring hibernate 整合
对于hibernate 和 spring 的整合,我做了一个小小的记录。方便以后使用,也方便新手们快速入门。下面正如正题吧。
我使用的工具是eclipse。首先,将需要的jar包添加到lib中。下面以 实体->实体类对应数据库表配置->spring 配置 ->数据操作->web.xml配置。
实体类如下:
package com.joshua.entiy;
public class User {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
实体类映射文件(User.hbm.xml):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.joshua.entiy">
<class name="User" table="client">
<id name="id" column="id">
<generator class="native"></generator>
</id>
<property name="name" type="string" column="name"></property>
</class>
</hibernate-mapping>
spring 配置 (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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/>
<property name="url" value="jdbc:sqlserver://localhost:1433;DatabaseName=shdba"/>
<property name="username" value="sa"/>
<property name="password" value="sa"/>
</bean>
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="mappingResources">
<list>
<value>User.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="sessionFactory" class="com.joshua.dao.SessionData">
<property name="sessionFactory"><ref local="mySessionFactory"/></property>
</bean>
<!-- 使用hibernateTemplate 进行数据库管理 -->
<bean id="sessionFactoryTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate" >
<property name="sessionFactory"><ref bean="sesionFactory"></ref></property>
</bean>
<bean id="user" class="com.joshua.entiy.User"/>
</beans>
数据操作部分:
package com.joshua.dao;
import org.hibernate.SessionFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.joshua.entiy.User;
public class SessionTest {
public static void main(String[] args) {
ClassPathXmlApplicationContext cx = new ClassPathXmlApplicationContext("beans.xml");
SessionData sessionFactory = (SessionData)cx.getBean("sessionFactory");
User u = (User)cx.getBean("user");
u.setId(1);
u.setName("joshua");
sessionFactory.save(u);
SessionFactory sessions = sessionFactory.getSessionFactory();
System.out.println("success!" + sessions);
}
}
web.xml配置:
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/beans.xml </param-value>
</context-param>
<context-param>
<param-name></param-name>
<param-value></param-value>
</context-param>
<!-- Bootstrap the root application context as usual using ContextLoaderListener -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<!-- map all requests for /hello* to the dispatcher servlet -->
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.form</url-pattern>
</servlet-mapping>
</web-app>
到此为止,spring 和 hibernate的整合已经完毕。希望这个简单的例子对大家有所帮助。
