spring3+hibernate4搭建

本框架以商品购物平台项目为例，用到spring3mvc和hibernate4，主要搭建步骤如下:

1、搭建spring3MVC
2、整合hiebernate4

【搭建spring3MVC】
（1）放入sping3所需的库、commons-logging-1.0.4.jar、jstl.jar
（2）配置web.xml,启动spring和mvc

<?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">
  <display-name>spring3hibernate4</display-name> 
  
  <!-- Spring配置文件开始  -->    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:spring-config.xml
        </param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <!-- Spring配置文件结束 -->
    
    <!-- Spring MVC配置开始 -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- Spring MVC配置开始 -->
    
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

（3）建立spring和mvc的配置文件
spring-config.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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
       ">
       
       <!-- 扫描注解Bean -->
    <context:component-scan base-package="com.it.app">
    	<!-- 通过exclude-filter 把所有 @Controller注解的表现层控制器组件排除 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    
</beans>

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" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/util
        http://www.springframework.org/schema/util/spring-util-3.1.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.1.xsd
        http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd" >
       
       <!-- 开启controller注解支持 -->
    <!-- 注：如果base-package=com.it.app 则注解事务不起作用 TODO 读源码 -->
    <context:component-scan base-package="com.it.app.web.controller">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- -->
    <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:order="3">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="contentType" value="text/html"/>        
        <property name="prefix" value="/WEB-INF/views/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    
</beans>

（4）创建一个商品控制器GoodsController和商品列表视图goods_list.jsp
GoodsController

/**
 * 
 */
package com.it.app.web.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @author cwd
 *
 */
@Controller
@RequestMapping(value="/goods")
public class GoodsController {
	
	@RequestMapping(value="list")
	public String list(){
		System.out.println("GoodsController.list:Passing through...");
		return "goods_list";
	}
	
}

goods_list.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
goods list!
</body>
</html>

【测试效果】
输入url：http://localhost:8180/spring3hibernate4/goods/list
网页输出内容：goods list!

【整合hibernate4】
（1）放入hibernate4所需的库、mysql连接驱动库 、dbcp库（commons-dbcp.jar和commons-pool.jar）
（2）在spring配置文件中加入数据源DataSource和hibernate4的相关配置

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">	
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url"
			value="jdbc:mysql://localhost:3306/shop?characterEncoding=UTF-8" />
		<property name="username" value="root" />
		<property name="password" value="xyz" />
	</bean>

  	<!-- 可追加配置二级缓存 -->
  	<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" >
    	<property name="dataSource" ref="dataSource"/>
    	<property name="packagesToScan">
			<list>
				<value>com.it.app</value>
			</list>
		</property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.query.substitutions">true 1, false 0</prop>
                <prop key="hibernate.default_batch_fetch_size">16</prop>
                <prop key="hibernate.max_fetch_depth">2</prop>
                <prop key="hibernate.generate_statistics">true</prop>
                <prop key="hibernate.bytecode.use_reflection_optimizer">true</prop>
                <prop key="hibernate.current_session_context_class">thread</prop>
                
            </props>
        </property>
  	</bean>

（3）以商品为例建立相应的实体domain、数据访问dao、服务service，并且修改相应的控制器controller
Goods.java

/**
 * 
 */
package com.it.app.domain;

import java.io.Serializable;

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;

/**
 * @author cwd
 *
 */
@Entity
@Table(name="goods")
public class Goods implements Serializable {
	//商品编号id，商品名称name，商品类型type，商品价格price
	@Id
	@Column(name="id",length=32,nullable=false,unique=true)
	@GenericGenerator(name="generator",strategy="uuid.hex")
	@GeneratedValue(generator="generator")
	private String id;
	@Column
	private String name;
	@Column
	private String type;
	@Column
	private double price;
	
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getType() {
		return type;
	}
	public void setType(String type) {
		this.type = type;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}

}

GoodsDao.java

package com.it.app.dao;


import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Repository;

import com.it.app.domain.Goods;

@Repository
public class GoodsDao {
	@Autowired
	@Qualifier("sessionFactory")
	private SessionFactory sessionFactory;

	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}
	
	public void save(){
		Session session = this.getSessionFactory().getCurrentSession();
		Transaction tr = session.beginTransaction();
		Goods goods = new Goods();
		goods.setName("spring touch");
		goods.setType("book");
		goods.setPrice(40.5);
		session.save(goods);
		tr.commit();		
	}
	
	

}

GoodsService.java

/**
 * 
 */
package com.it.app.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.it.app.dao.GoodsDao;

/**
 * @author cwd
 *
 */
@Service
public class GoodsService {
	@Autowired
	private GoodsDao goodsDao;

	public GoodsDao getGoodsDao() {
		return goodsDao;
	}

	public void setGoodsDao(GoodsDao goodsDao) {
		this.goodsDao = goodsDao;
	}
	
	public void save(){
		this.goodsDao.save();
	}

}

修改GoodsController.java，操作数据库，修改后如下：

/**
 * 
 */
package com.it.app.web.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.it.app.service.GoodsService;

/**
 * @author cwd
 *
 */
@Controller
@RequestMapping(value="/goods")
public class GoodsController {
	@Autowired
	private GoodsService goodsService;
	
	@RequestMapping(value="list")
	public String list(){
		System.out.println("GoodsController.list:Passing through...");
		this.goodsService.save();
		return "goods_list";
	}

	public GoodsService getGoodsService() {
		return goodsService;
	}

	public void setGoodsService(GoodsService goodsService) {
		this.goodsService = goodsService;
	}
	
}

【Spring集成测试】
（1）加入JUnit4测试库
（2）创建一个测试类用来测试sping+hibernate
创建商品服务测试类GoodsServiceTest.java

/**
 * 
 */
package com.it.app.service;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @author cwd
 *
 */
@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations = {"classpath:spring-config.xml"})  
public class GoodsServiceTest {
	@Autowired
	private GoodsService goodsService;	
	
	@Test
	public	void testSave(){
		goodsService.save();
	}
}

最后测试类测试和web测试方式都成功，框架搭建成功！
