EmployeeService:Spring、Spring MVC、RESTful、Hibernate、MySQL 员工服务 REST、Spring、Spring MVC、Hibernate、MySQL 如何运行：从github下载并打开这个项目。使用“mvn idea:idea”在 Intellij Idea 中创建项目为您的数据库更改 database.properties。默认情况下，它将是：名称“test”，用户名 - “root”和密码 - “132435” 在控制台中将测试数据插入数据库。您可以在 EmployeeService/src/main/resources/testDataForDatabase.txt 中找到它使用“mvn tomcat7:deploy -Dtomcat.username=YOUR_USERNAME -Dtomcat.password=YOUR_PASSWORD”在 tomcat 服务器中部署这个应用程序。或者从 tomcat 管理器页面部署立即下载

作为一个初学者，在网上找了很久都没有找到一个简单的例子。最终自己看明白了写出了一个。贴在这里，

首先是项目结构

超简单的结构，只是基本实现了mvc,hibernate/spring事务的使用。

基本实现为在index.jsp里点击一个按钮，将数据提交至后台的controller,然后对数据库进行操作，然后返回前台qiuqiu.jsp数据。

实现步骤1：

1:
建立工程，加入所有jar包

2：配置mvc 

1）配置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"
	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>Tests</display-name>
	<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>
	<!-- spring加载多个配置文件是就要配置 context-param实际上是个键值对，作为项目的一个上下文对象

而spring的监听器ContextLoaderListener加载时，会查找名为contextConfigLocation的参数 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value> classpath*:com/gaoyajun/spring/xmls/*.xml</param-value>
	</context-param>
	<!-- 配置Spring监听 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	 <load-on-startup>1</load-on-startup>  
	</servlet>
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	<!-- 配置Session -->  
  <filter>  
    <filter-name>openSession</filter-name>  
    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>  
  </filter>  
  <filter-mapping>  
    <filter-name>openSession</filter-name>  
    <url-pattern>/*</url-pattern>  
  </filter-mapping>  
</web-app>

2)配置springmvc-servlet.xml 主要就是视图解析器和扫描器

这个简单项目除了这两个东西没有任何别的。

<?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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<div yne-bulb-block="paragraph" style="white-space: pre-wrap; line-height: 1.875; font-size: 14px;"><!--视图解析器配置--></div>

<bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

<div yne-bulb-block="paragraph" style="white-space: pre-wrap; line-height: 1.875; font-size: 14px;"><!-- mvc扫描器--></div>
<mvc:annotation-driven/>
<context:component-scan base-package="com"></context:component-scan>
</beans>

当配置完这里，一个mvc的框架都配置成功了。在建立一个控制器一个前端jsp基本就可以获取到前后端通信了。

控制器：TestController

package com.gaoyajun.spring.conroller;

import java.util.HashMap;
import java.util.Map;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.gaoyajun.spring.dao.UserDao;
import com.gaoyajun.spring.entity.User;

@Controller
public class TestController {
	 @Resource(name="userDao")  
	    private UserDao userdao;  
	@RequestMapping(value="/love.do",method=RequestMethod.POST)//注解的方式，将访问这个方法的地址设置为love.do
	public  ModelAndView add(User user){//使用对象的方式
		ModelAndView mdv=new ModelAndView("qiuqiu");//最终要返回数据的目标jsp
		System.out.println("获得数据");
		System.out.println(user);
		userdao.addUser(user);
		return mdv;
	}
	@RequestMapping(value="/love1.do",method=RequestMethod.POST)
	public  ModelAndView query(User user){//查询的方法，
		   Map<String,Object> data = new HashMap<String,Object>();
		   user= userdao.getUser("1");
		     data.put("user",user);
		
		
		return new ModelAndView("qiuqiu2",data) ;
	}
}

此处为控制器，主要是与前端进行交互，一开始没有搞懂其他的首先做的是弄通mvc,类里面只有如下的一个简单方法没有User等实体类，方法很简单纯粹用于测试的：

@RequestMapping(value="/love0.do",method=RequestMethod.POST)
	public  String Test(<span style="font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px;">String name</span><span style="white-space: pre-wrap; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px;">,String age,Model model</span><span style="white-space: pre-wrap; font-family: Arial, Helvetica, sans-serif;"> ){//查询的方法，</span><pre name="code" class="java" style="font-size: 14px; line-height: 26.25px;">		<span style="font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">    model.addAttribute(</span><span class="string" style="margin: 0px; padding: 0px; border: none; color: blue; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">"name"</span><span style="margin: 0px; padding: 0px; border: none; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">, name);  </span>
		<span style="white-space: pre-wrap; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">model.addAttribute(</span><span class="string" style="white-space: pre-wrap; margin: 0px; padding: 0px; border: none; color: blue; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">"age"</span><span style="white-space: pre-wrap; margin: 0px; padding: 0px; border: none; font-family: Consolas, 'Courier New', Courier, mono, serif; line-height: 18px; background-color: rgb(248, 248, 248);">, age); </span>

		return "qiuqiu";//返回数据至qiuqiu.jsp

;}

然后写一个qiuqiu.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>
获取的参数是<a>${name}</a>
获取的参数是<a>${age}</a>
</body>
</html>

基本到这里实现了一个简单的springmvc的框架。

然后向里面添加hibernate以及spring事务

3 配置hibernate，spring事务，基本主要就是配置一个xml文件。spring-common.jsp
<?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:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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">
<!-- 此xml用于连接数据库设置事务等公用方式 -->
 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >  
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>  
        <property name="url" value="jdbc:mysql://localhost/test"></property>  
        <property name="username" value="root"></property>  
        <property name="password" value="root"></property>  
    </bean>  
      
    <!-- 配置SessionFactory -->  
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" />  
        <property name="hibernateProperties">  
            <props>  
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>  
                <prop key="hibernate.hbm2ddl.auto">update</prop>  
                <prop key="hibernate.show_sql">true</prop>  
                <prop key="hibernate.format_sql">true</prop>  
            </props>  
        </property>  
        <!--注解的实体  -->
        <property name="annotatedClasses">  
            <list>  
                <value>com.gaoyajun.spring.entity.User</value>  
            </list>  
        </property>  
    </bean>  
    <!-- 配置一个事务管理器 -->  
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">  
        <property name="sessionFactory" ref="sessionFactory"/>  
    </bean>  
      
    <!-- 配置事务，使用代理的方式 -->  
    <bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">    
         <!-- 为事务代理工厂Bean注入事务管理器 -->
        <property name="transactionManager" ref="transactionManager"></property>    
         <property name="target" ref="userDao" />
        <property name="transactionAttributes">    
            <props>    
               <prop key="*">PROPAGATION_REQUIRED </prop>   
            </props>    
        </property>    
    </bean>   
    <bean id="userDaoBase" class="com.gaoyajun.spring.dao.impl.UserDaoImpl">  
        <property name="sessionFactory" ref="sessionFactory"></property>  
    </bean>
<!--注意这里的userDao,在上面transactionManager的target的指向其实是这个bean,这个是spring的事务的配置，为bean添加同一的事务管理-->

 <bean id="userDao" parent="transactionProxy">   
 <property name="target" ref="userDaoBase" />   
 </bean>   
</beans>


然后再配置完成后开始做简单的数据库的交互
第一步，添加用户，先写一个用户表的实体user.java
package com.gaoyajun.spring.entity;

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;

@Entity  
@Table(name="T_USER")  
public class User {
	  @Id  
	  @GeneratedValue(generator="system-uuid")  
	  @GenericGenerator(name = "system-uuid",strategy="uuid")  
	   @Column(length=32) 
	private String id;
	  @Column(length=32)  
	private String name;
	  @Column(length=32)  
	private String age;
	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 getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", age=" + age + "]";
	}
	
}
然后再写用户类的操作的类
UserDao,以及实现类UserDaoImpl,
package com.gaoyajun.spring.dao;


import com.gaoyajun.spring.entity.User;

public interface  UserDao {
public User getUser(String id);
public boolean updateUser(User user);  
public void addUser(User user);
}


package com.gaoyajun.spring.dao.impl;

import org.hibernate.Query;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;

import com.gaoyajun.spring.dao.UserDao;
import com.gaoyajun.spring.entity.User;

public class UserDaoImpl implements UserDao {
	   private SessionFactory sessionFactory;  
	   
	    public void setSessionFactory(SessionFactory sessionFactory) {  
	        this.sessionFactory = sessionFactory;  
	    }  
	@Override
	public User getUser(String id) {
		   String hql = "from User u where u.id=?";  
	        Query query = sessionFactory.getCurrentSession().createQuery(hql);  
	        query.setString(0, id);  
	        return (User)query.uniqueResult();  		
	}

	@Override
	public boolean updateUser(User user) {
		 sessionFactory.getCurrentSession().save(user);  
		return false;
	}
	@Override
	public void addUser(User user) {		
		 sessionFactory.getCurrentSession().save(user);  
		
	}

}
然后再看前端
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!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=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="love.do" method="post">
<input value="李四" name="name">
<input  value="二十" name="age">
<input type="submit" value="提交">
</form>
</body>
</html>

流程为工程启动，进入index.jsp。点击提交，进入love.do，然后在userDao里保存数据至数据库。
