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:
(3)建立spring和mvc的配置文件
spring-config.xml
(4)创建一个商品控制器GoodsController和商品列表视图goods_list.jsp
GoodsController
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
(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
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">

<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"

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"

<!-- 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!
