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; @Override
public 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: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.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/tx
http://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.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
http://www.springframework.org/schema/tx
http://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.X
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.150.63:3306/test?createDatabaseIfNotExist=true
jdbc.user=root
jdbc.pass=root111111 # hibernate.X
hibernate.connection.driverClass=org.gjt.mm.mysql.Driver
hibernate.connection.url=jdbc:mysql://192.168.150.63:3306/test
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.connection.username=root
hibernate.connection.password=root111111
hibernate.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, AbstractHibernateDao

com.lei.demo.dao: IUserDao

com.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();
} @Override
public final T findOne(final long id) {
return (T)getCurrentSession().get(clazz, id);
} @Override
public final List<T> findAll() {
return getCurrentSession().createQuery("from " + clazz.getName()).list();
} @Override
public final void create(final T entity) {
Preconditions.checkNotNull(entity);
// getCurrentSession().persist(entity);
getCurrentSession().saveOrUpdate(entity);
} @Override
public final T update(final T entity) {
Preconditions.checkNotNull(entity);
getCurrentSession().update(entity);
return entity;
//return (T)getCurrentSession().merge(entity);
} @Override
public final void delete(final T entity) {
Preconditions.checkNotNull(entity);
getCurrentSession().delete(entity);
} @Override
public 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IOperations

package 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: AbstractService

com.lei.demo.service: IUserService

com.lei.demo.service.impl: UserService

AbstractService.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; @Transactional
public abstract class AbstractService<T extends Serializable> implements IOperations<T> { protected abstract IOperations<T> getDao(); @Override
public T findOne(final long id) {
return getDao().findOne(id);
} @Override
public List<T> findAll() {
return getDao().findAll();
} @Override
public void create(final T entity) {
getDao().create(entity);
} @Override
public T update(final T entity) {
return getDao().update(entity);
} @Override
public void delete(final T entity) {
getDao().delete(entity);
} @Override
public 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();
} @Override
protected 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.jsp

WEB-INF/jsp/user/edit.jsp

WEB-INF/jsp/user/list.jsp

WEB-INF/jsp/user/detail.jsp

以下是具体页面代码

WEB-INF/jsp/user/add.jsp

</html>

写Controller访问上边的jsp,UserController.java

package com.lei.demo.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView; import com.lei.demo.model.User;
import com.lei.demo.service.IUserService; @Controller
@RequestMapping("/user")
public class UserController { @Resource(name="userService")
private IUserService userService; @RequestMapping(value="/count",method=RequestMethod.GET)
public ModelAndView userCount() { int count = userService.findAll().size(); ModelAndView mv = new ModelAndView();
mv.addObject("userCount", count);

} @RequestMapping(value="/edit/{userid}",method=RequestMethod.GET)
public ModelAndView getEdit(@PathVariable Long userid,Model model){
User user = userService.findOne(userid);
model.addAttribute("userAttribute", user);
ModelAndView mv = new ModelAndView();
mv.setViewName("user/edit");
