Spring4 MVC Hibernate4集成 Annotation

已经充分封装DAO层和Service层

一、本文所用环境

Spring4.0.3.RELEASE、Hibernate4.3.5.Final、Mysql

二、工程目录

三、 Maven添加依赖

用Maven创建项目，pom.xml如下： <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

四、新建数据库表

数据库采用Mysql，新建user表，我们演示操作此表对user进行增删改查DROP TABLE IF EXISTS `user`;CREATE TABLE `user` （`id` int（11） NOT NULL AUTO_INCREMENT,`age` int（11） DEFAULT NULL,`nice_name` varchar（32） DEFAULT NULL,`name` varchar（32） DEFAULT NULL,PRIMARY KEY （`id`）） ENGINE=InnoDB AUTO_INCREMENT=29 DEFAULT CHARSET=utf8;在model层下，创建Entity类Users.java见下package com.lei.demo.model;import java.io.Serializable;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;@Entity（name="User"）public class User implements Serializable {private static final long serialVersionUID = 1L;public User（）{super（）;}@Id@GeneratedValue（strategy=GenerationType.AUTO）@Column（name="id"）private Long id;@Column（name="name",length=32）private String name;@Column（name="age"）private Integer age;@Column（name="nice_name",length=32）private String nice_name;@Overridepublic String toString（） {return "User [id=" + id + ", user_name=" + name + ", age=" + age+ ", nice_name=" + nice_name + "]";}public final Long getId（） {return id;}public final void setId（Long id） {this.id = id;}public final String getName（） {return name;}public final void setName（String name） {this.name = name;}public final Integer getAge（） {return age;}public final void setAge（Integer age） {this.age = age;}public final String getNice_name（） {return nice_name;}public final void setNice_name（String nice_name） {this.nice_name = nice_name;}}

五、配置文件

1. 首先看一下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" xmlns:web="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_3_0.xsd" id="WebApp_ID" version="3.0"><display-name>Archetype Created Web Application</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:/spring-*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><！-- 定义DispatcherServlet --><servlet><servlet-name>mvc-dispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><！-- 默认/WEB-INF/[servlet名字]-servlet.xml加载上下文，如果配置了contextConfigLocation参数，将使用classpath:/mvc-dispatcher-servlet.xml加载上下文--><param-name>contextConfigLocation</param-name><param-value>classpath:/mvc-dispatcher-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><！-- 拦截匹配的请求，这里所有请求采用名字为mvc-dispatcher的DispatcherServlet处理 --><servlet-mapping><servlet-name>mvc-dispatcher</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

2. mvc-dispatcher-servlet.xml

<？xml version="1.0" encoding="UTF-8"？><beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:p="http://www.springframework.org/schema/p"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-4.0.xsd"><！-- 启动自动扫描该包下所有的Bean（例如@Controller） --><context:component-scan base-package="com.lei.demo" /><！-- 基于注释的事务，当注释中发现@Transactional时，使用id为“transactionManager”的事务管理器--><！-- 如果没有设置transaction-manager的值，则spring以缺省默认的事务管理器来处理事务，默认事务管理器为第一个加载的事务管理器 --><tx:annotation-driven transaction-manager="transactionManager"/><！-- 定义视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix"><value>/WEB-INF/jsp/</value></property><property name="suffix"><value>.jsp</value></property></bean> </beans>

3. Spring-hibernate的整合

spring-hibernate.xml文件<？xml version="1.0" encoding="UTF-8"？><beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-4.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-4.0.xsd"><！-- Hibernate4 --><！-- 加载资源文件其中包含变量信息，必须在Spring配置文件的最前面加载，即第一个加载--><context:property-placeholder location="classpath:persistence-mysql.properties" /><bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="packagesToScan"><list><！-- 可以加多个包 --><value>com.lei.demo.model</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">${hibernate.dialect}</prop><prop key="hibernate.show_sql">${hibernate.show_sql}</prop></props></property></bean><！-- 数据库映射 --><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="${jdbc.driverClassName}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.user}" /><property name="password" value="${jdbc.pass}" /> </bean> <！-- 配置Hibernate事务管理器 --><bean id="transactionManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /> </bean><！-- 配置事务异常封装 --> <bean id="persistenceExceptionTranslationPostProcessor"class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /></beans>资源文件persistence-mysql.properties如下：# jdbc.Xjdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://192.168.150.63:3306/test？createDatabaseIfNotExist=truejdbc.user=rootjdbc.pass=root111111# hibernate.Xhibernate.connection.driverClass=org.gjt.mm.mysql.Driverhibernate.connection.url=jdbc:mysql://192.168.150.63:3306/testhibernate.dialect=org.hibernate.dialect.MySQL5Dialecthibernate.connection.username=roothibernate.connection.password=root111111hibernate.show_sql=true

六、 Model层

此处model层只有一个User类，见前文user.java。

七、 DAO层

DAO层包括3个包，各个包中类如下：com.lei.demo.dao.common: IOperations, AbstractHibernateDaocom.lei.demo.dao: IUserDaocom.lei.demo.dao.impl: UserDao代码如下：IOperations.java，通用的操作接口package com.lei.demo.dao.common;import java.io.Serializable;import java.util.List;/* * 通用的操作接口 */public interface IOperations<T extends Serializable> { T findOne（final long id）;List<T> findAll（）;void create（final T entity）;T update（final T entity）;void delete（final T entity）;void deleteById（final long entityId）;}AbstractHibernateDao.java实现了IOperations接口，所有DAO都需要继承此类，这样就避免重复的写一些CURD。package com.lei.demo.dao.common;import java.io.Serializable;import java.util.List;import javax.annotation.Resource;import org.hibernate.Session;import org.hibernate.SessionFactory;import com.google.common.base.Preconditions;@SuppressWarnings（"unchecked"）public abstract class AbstractHibernateDao<T extends Serializable> implements IOperations<T> {private Class<T> clazz;@Resource（name="sessionFactory"）private SessionFactory sessionFactory;protected final void setClazz（final Class<T> clazzToSet） {this.clazz = Preconditions.checkNotNull（clazzToSet）;}protected final Session getCurrentSession（） {return sessionFactory.getCurrentSession（）;}@Overridepublic final T findOne（final long id） {return （T）getCurrentSession（）.get（clazz, id）;}@Overridepublic final List<T> findAll（） {return getCurrentSession（）.createQuery（"from " + clazz.getName（））.list（）;}@Overridepublic final void create（final T entity） { Preconditions.checkNotNull（entity）; // getCurrentSession（）.persist（entity）; getCurrentSession（）.saveOrUpdate（entity）;}@Overridepublic final T update（final T entity） {Preconditions.checkNotNull（entity）;getCurrentSession（）.update（entity）;return entity;//return （T）getCurrentSession（）.merge（entity）;}@Overridepublic final void delete（final T entity） { Preconditions.checkNotNull（entity）; getCurrentSession（）.delete（entity）;}@Overridepublic final void deleteById（final long entityId） {final T entity = findOne（entityId）;Preconditions.checkState（entity ！= null）;delete（entity）;}}IUserDao.java具体的DAO的接口，继承了IOperationspackage com.lei.demo.dao;import com.lei.demo.dao.common.IOperations;import com.lei.demo.model.User;public interface IUserDao extends IOperations<User> {//让所有的DAO都实现基本的操作接口IOperations//除了实现IOperations中的基本操作之外，特定的DAO要实现其他操作可以在对应的接口DAO中定义方法，//此处UserDao的接口IUserDao不需要实现其他方法}UserDao.java具体的DAO实现package com.lei.demo.dao.impl;import org.springframework.stereotype.Repository;import com.lei.demo.dao.IUserDao;import com.lei.demo.dao.common.AbstractHibernateDao;import com.lei.demo.model.User;@Repository（"usersDao"）public class UserDao extends AbstractHibernateDao<User> implements IUserDao {public UserDao（） {super（）;setClazz（User.class）;}}至此，DAO层已经完成。

八、 Service层

Service层包括3个包，各个包中类如下：com.lei.demo.service.common: AbstractServicecom.lei.demo.service: IUserServicecom.lei.demo.service.impl: UserServiceAbstractService.java,实现了IOperations，所有的Service都要继承此类，这样就避免了重复实现通用的方法，注意类前的注释“@Transactional”，表示其中所有的方法都需要引入事务，代码如下：package com.lei.demo.service.common;import java.io.Serializable;import java.util.List;import org.springframework.transaction.annotation.Transactional;import com.lei.demo.dao.common.IOperations;@Transactionalpublic abstract class AbstractService<T extends Serializable> implements IOperations<T> {protected abstract IOperations<T> getDao（）;@Overridepublic T findOne（final long id） {return getDao（）.findOne（id）;}@Overridepublic List<T> findAll（） {return getDao（）.findAll（）;}@Overridepublic void create（final T entity） {getDao（）.create（entity）;}@Overridepublic T update（final T entity） {return getDao（）.update（entity）;}@Overridepublic void delete（final T entity） {getDao（）.delete（entity）;}@Overridepublic void deleteById（long entityId） {getDao（）.deleteById（entityId）;}}IUserService.java接口package com.lei.demo.service;

import com.lei.demo.dao.common.IOperations;
import com.lei.demo.model.User;

public interface IUserService extends IOperations<User> {

} UserService.java，具体的Service实现类就很简单了，因为大部分通用的方法都在其继承的虚类AbstractService中实现了，这里只要注入具体的dao即可：package com.lei.demo.service.impl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.lei.demo.dao.IUserDao;import com.lei.demo.dao.common.IOperations;import com.lei.demo.model.User;import com.lei.demo.service.IUserService;import com.lei.demo.service.common.AbstractService;@Service（"userService"）public class UserService extends AbstractService<User> implements IUserService {@Resource（name="usersDao"）private IUserDao dao;public UserService（） {super（）;}@Overrideprotected IOperations<User> getDao（） {return this.dao;}}

九、 JSP页面和Controller

Jsp页面放在WEB-INF/jsp/user/…下，分别是user的增删改查页面，WEB-INF/jsp/user/add.jspWEB-INF/jsp/user/edit.jspWEB-INF/jsp/user/list.jspWEB-INF/jsp/user/detail.jsp以下是具体页面代码WEB-INF/jsp/user/add.jsp<%@ page language="java" contentType="text/html;
