搭建SpringMVC+Hibernate4+Spring3+Ajax+Maven项目 / 憋错料

首先新建一个Maven项目，百度一下会有很多实例，这里就不介绍了，直接奔主题。

如题：这里使用的是Hibernate4和Spring3，使用的JPA和Spring注解，然后JDK版本是1.7

下面这张图片演示的是整个项目的结构图。

-------------------------------------------------------

---------------------------------------------------

首先配置pom.xml，将所需的jar包配置好，如下，


<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</dependencies>

</project>

然后建日志配置文件log4j.properties，如下


log4j.rootLogger=INFO,A1,R

 

log4j.appender.A1=org.apache.log4j.ConsoleAppender

log4j.appender.A1.Target=System.out

log4j.appender.A1.layout=org.apache.log4j.PatternLayout

log4j.appender.A1.layout.ConversionPattern=[%c]%m%n

 

log4j.appender.R=org.apache.log4j.RollingFileAppender 

log4j.appender.R.File=sshf.log

log4j.appender.R.MaxFileSize=10MB

log4j.appender.R.Threshold=ALL

log4j.appender.R.layout=org.apache.log4j.PatternLayout

log4j.appender.R.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

继续建jdbc配置文件config.properties，如下，其中很多多余的，可以按照自己需要的进行配置，相信都会看得懂的，


#\u5C5E\u6027\u6587\u4EF6

 

#Oracle \u7684\u914D\u7F6E

#hibernate.dialect=org.hibernate.dialect.OracleDialect

#driverClassName=oracle.jdbc.driver.OracleDriver

#validationQuery=SELECT 1 FROM DUAL

#jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl

#jdbc_username=

#jdbc_password=

 

#SQLServer \u7684\u914D\u7F6E

#hibernate.dialect=org.hibernate.dialect.SQLServerDialect

#driverClassName=net.sourceforge.jtds.jdbc.Driver

#validationQuery=SELECT 1

#jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy

#Derby \u7684\u914D\u7F6E

#hibernate.dialect=org.hibernate.dialect.DerbyDialect

#driverClassName=org.apache.derby.jdbc.EmbeddedDriver

#validationQuery=SELECT 1

#jdbc_url=jdbc:derby:sy;create=true

#jdbc_username=

#jdbc_password=

 

#MySQL \u7684\u914D\u7F6E

hibernate.dialect=org.hibernate.dialect.MySQLDialect

driverClassName=com.mysql.jdbc.Driver

validationQuery=SELECT 1

jdbc_url=jdbc:mysql://localhost:3306/phn?useUnicode=true&characterEncoding=utf-8

jdbc_username=root

jdbc_password=123456

 

hibernate.hbm2ddl.auto=update

hibernate.show_sql=true

hibernate.format_sql=false

 

sessionInfoName=sessionInfo

 

uploadFieldName=filedata

uploadFileMaxSize=20971520

uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid

uploadDirectory=attached

接着继续配置web.xml文件，其中有3个文件，名为：spring.xml,spring-hibernate.xml,spring-mvc.xml，顾名思义相信大家应该也可以猜出一部分，其中spring.xml和spring-hibernate.xml是可以合并成applicationcontext.xml文件的，这里是为了区分以后可能会有什么Spring-mybatis.xml等等，


<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</filter>

	<!-- encoding filter for jsp page -->

	<filter-mapping>

		<filter-name>encodingFilter</filter-name>

		<url-pattern>/*</url-pattern>

	</filter-mapping>

 

 

	<listener>

	</listener>

 

	<welcome-file-list>

		<welcome-file>/WEB-INF/jsp/login.jsp</welcome-file>

	</welcome-file-list>

</web-app>

接着我们开始建Spring.xml，如下，就不解释具体元素的意义了，直接看注释吧，写的很详细的，


<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

	<!-- 引入属性文件 -->

	<context:property-placeholder location="classpath:config.properties" />

 

	<!-- 自动扫描dao和service包(自动注入) -->

	<context:component-scan base-package="com.phn.dao,com.phn.service" />

 

</beans>

继续建spring-hibernate.xml，同样注释也都比较详细了，大家仔细看是可以看懂的，

继续建spring-mvc.xml，这里也不讲了哈，感觉没什么讲的，哈哈，有几个需要注意的地方最后讲，先把项目搭起来再说，


<?xml version="1.0" encoding="UTF-8"?>

	<!-- 注解扫描包 -->

	<!-- <context:component-scan /> -->

	<!-- 扫描指定的包中的类上的注解，常用的注解有： -->

	</bean>

</beans>

到这里配置的已经差不多了，接下来开始编写服务器端的代码。

记得先建立一个数据库哈，这个不要忘记了，我建的是phn命名的数据库。

大家先按照我对包命名的方式对自己的项目建好响应的包吧，这样快速好继续一下步骤。

先从实体开始吧，在model包中建一个UserEntity类，代码如下，这里使用了Java JPA，已经在Spring-Hibernate.xml里面配置了可以自动生成数据库表的相应代码了。


package com.phn.model;

 

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.Table;

 

/**

 * @author phn

 */

@Table(name="t_user")

@Entity

public class UserEntity {

	private int id;

	private String username;

	private String password;

	private boolean sex; // 默认为0；0表示男，1表示女

 

	@Id

	@GeneratedValue(strategy = GenerationType.IDENTITY)

	@Column(name = "UID", nullable = false, length = 9)

	public int getId() {

		return id;

	}

 

	public void setId(int id) {

		this.id = id;

	}

 

	@Column(name = "UNAME", nullable = false, length = 20)

	public String getUsername() {

		return username;

	}

 

	public void setUsername(String username) {

		this.username = username;

	}

 

	@Column(name = "UPASSWORD", nullable = false, length = 32)

	public String getPassword() {

		return password;

	}

 

	public void setPassword(String password) {

		this.password = password;

	}

 

	@Column(name = "USEX", nullable = false, length = 1)

	public boolean isSex() {

		return sex;

	}

 

	public void setSex(boolean sex) {

		this.sex = sex;

	}

 

	@Override

	public String toString() {

		return "User [ \nid : " + this.id + "\nusername : " + this.username

				+ "\npassword : " + this.password + "\nsex : " + this.sex

				+ " ]";

	}

 

}

接着开始编写数据访问层（DAO层）接口，新建IUserDao接口，添加一下代码，这里就写了一个方法判断用户是否存在，用来验证用户登录。


package com.phn.dao;

 

import com.phn.model.UserEntity;

 

/**

 * @author phn

 */

public interface IUserDao {

	public boolean isExist(UserEntity user);

}

继续编写数据访问层（DAO层）的实现类UserDaoImpl类，依赖注入使用的是@Resource注解，还可以用@Autowired注解的，这里先不解释，后面再解释，继续我们项目的搭建。


package com.phn.dao.impl;

 

import javax.annotation.Resource;

 

import org.hibernate.Query;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.stereotype.Repository;

 

import com.phn.dao.IUserDao;

import com.phn.model.UserEntity;

 

/**

 * @author phn

 */

 

@Repository("userDao")

public class UserDaoImpl implements IUserDao {

	@Resource

	protected SessionFactory sessionFactory;

 

 

	public Session getSession() {

		return sessionFactory.getCurrentSession();

	}

 

	public void setSessionFactory(SessionFactory sessionFactory) {

		this.sessionFactory = sessionFactory;

	}

	

	@Override

	public boolean isExist(UserEntity user) {

		Session session = this.getSession();

		String hql = "from UserEntity where username =? and password = ?";

		Query query = session.createQuery(hql);

		query.setString(0, user.getUsername());

		query.setString(1, user.getPassword());

		if (query.list().size() >= 1) {

			return true;

		}

		return false;

	}

}

数据访问层编写完了，我们测试看看方法可以用不咯

建一个UserDaoTest测试类，注意放在test资源包下面哈，代码如下，这里关于Junit+Spring测试使用注解引入单个和多个文件的区别留着后面讲，哈哈，是不是好多坑了，没事，等会一个一个填，我们先把项目弄好跑起来，最后来研究细节，这是我的学习方法，个人觉得要是整了半天最后弄不好不就白干了，哈哈，不说多了，继续，


package com.phn.dao;

 

import javax.annotation.Resource;

 

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import org.springframework.test.context.transaction.TransactionConfiguration;

import org.springframework.transaction.annotation.Transactional;

 

import com.phn.model.UserEntity;

 

@ContextConfiguration(locations = {"classpath:spring.xml","classpath:spring-hibernate.xml"})

@RunWith(SpringJUnit4ClassRunner.class)

// defaultRollback=true不会改变数据库，false会改变数据库

@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)

@Transactional

public class UserDaoTest {

	@Resource

	private IUserDao userDao;

 

	@Test

	public void testIsExist() {

		UserEntity user = new UserEntity();

		user.setUsername("phn");

		user.setPassword("123456");

		boolean result = userDao.isExist(user);

		System.out.println(result);

	}

 

}

测试结果应该是对的吧，不对的话赶紧从前面开始看看什么地方错了，改正一下继续，看我的测试结果

继续编写业务逻辑层（Service层）接口，新建IUserService接口，代码如下，


package com.phn.service;

 

import com.phn.model.UserEntity;

 

/**

 * @author phn

 */

public interface IUserService {

	public boolean isExist(UserEntity user);

}

继续编写业务逻辑层（Service层）实现类UserServiceImpl类，这里使用了@Transactional事务标签，不能少的哈，不多说，还是后面解释。


package com.phn.service.impl;

 

import javax.annotation.Resource;

 

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

 

import com.phn.dao.IUserDao;

import com.phn.model.UserEntity;

import com.phn.service.IUserService;

 

/**

 * @author phn

 */

@Transactional

@Service("userService")

public class UserServiceImpl implements IUserService {

	@Resource

	private IUserDao userDao;

 

	@Override

	public boolean isExist(UserEntity user) {

		return userDao.isExist(user);

	}

 

}

业务逻辑层也ok了，我们测试一下，同样建一个UserServiceTest测试类，代码如下，其实和dao层的代码差不多，就是一些细节需要注意一下的话，后面讲，继续


package com.phn.service;

 

 

import javax.annotation.Resource;

 

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

 

import com.phn.model.UserEntity;

 

@ContextConfiguration(locations= {"classpath:spring.xml","classpath:spring-hibernate.xml"})

@RunWith(SpringJUnit4ClassRunner.class)

public class UserServiceTest {

	@Resource

	private IUserService userService;

	@Test

	public void testIsExist(){

		UserEntity user = new UserEntity();

		user.setUsername("phn");

		user.setPassword("123456");

		boolean result = userService.isExist(user);

		System.out.println(result);

	}

 

}

同样测试结果应该是对的吧，不对的话赶紧从前面开始看看什么地方错了，改正一下继续，我的测试结果如下

下面就开始控制层（Controller层或者又叫Action层）的编码，新建一个UserController类，代码如下


package com.phn.controller;

 

 

import java.util.HashMap;

import java.util.Map;

 

import javax.annotation.Resource;

 

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

import org.springframework.stereotype.Controller;

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

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

 

import com.phn.model.UserEntity;

import com.phn.service.IUserService;

 

/**

 * @author phn

 */

@Controller

@RequestMapping("/user")

public class UserController{

	@Resource

	private IUserService userService;

	

	@ResponseBody

	@RequestMapping(value="/login", method = RequestMethod.POST)

	public Map<String,Object> login( UserEntity user){

		Map<String,Object> map = new HashMap<String,Object>();

		System.out.println(user.toString());

		boolean loginResult = userService.isExist(user);

		map.put("loginResult", loginResult);

		return map;

	}

}

好啦，控制层写好了，下面测试，怎么测试呢，需要前台了，哈哈，ok，开始

看看我的项目的webapp文件夹

------------------------------------------------------------------

-------------------------------------------------------------------

建一个jsp，弄个简单的Ajax提交，通过传输Json数据来进行交互，这里是不是有点高大上，哈哈，前后端分离的路啊，不扯这个了，博主自己还不是很熟悉前后端分离的思想呢，慢慢来吧，少年，路还长着呢


<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%

	String path = request.getContextPath();

	String basePath = request.getScheme() + "://"

			+ request.getServerName() + ":" + request.getServerPort()

			+ path + "/";

%>

 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<base href="<%=basePath%>">

 

<title>登录</title>

 

<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="cache-control" content="no-cache">

<meta http-equiv="expires" content="0">

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

<meta http-equiv="description" content="This is my page">

 

<link rel="stylesheet" type="text/css" href="<%=basePath%>css/login.css">

<script type="text/javascript" src="<%=basePath%>js/jquery-1.8.2.min.js"></script>

<script type="text/javascript" src="<%=basePath%>js/md5.js"></script>

<script type="text/javascript" src="<%=basePath%>js/login.js"></script>

</head>

 

<body>

	<div>

		UserName:<input type="text" name="username" /> <br/>

		PassWord:<input type="password" name="password" /><br/> 

		<input type="submit" id="loginBtn" value="Login" />

	</div>

</body>

</html>

继续建一个js文件，login.js，代码如下，看到里面是不是进行了md5加密呀，这个是一个很简单的东西，你们可以不用那个md5加密，相信这个操作你们还是会的吧，就是去掉hex_md5($("input[name=password]").val());外面的那个hex_md5()就ok了，继续没有了呢


$(function() {

	$("#loginBtn").click(function() {

		console.log("login");

		var username = $("input[name=username]").val();

		var password = hex_md5($("input[name=password]").val());

		var user = {

			"username" : username,

			"password" : password

		};

		$.ajax({

			type : "post",

			dataType : "json",

			data : user,

			contentType : "application/x-www-form-urlencoded;charset=UTF-8",

			url : "user/login",

			// 同步async: false,（默认是true）;

			// 如上：false为同步，这个方法中的Ajax请求将整个浏览器锁死，

			// 只有test.jsp执行结束后，才可以执行其它操作。

			async : false,

			success : function(data) {

				if (false == data.loginResult) {

					alert("用户名或者密码错误，请重新登录！");

				} else if (true == data.loginResult) {

					alert("登录成功！");

					var indexUrl = window.location.protocol+"//"+window.location.host+window.location.pathname+"html/index.html";

					window.location = indexUrl;

				}

			},

			error : function() {

				alert("服务器发生故障，请尝试重新登录！");

			}

		});

	});

 

});

还有一个登录成功的页面，index.html,代码如下


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

 

<title>欢迎页面</title>

 

<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="cache-control" content="no-cache">

<meta http-equiv="expires" content="0">

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

<meta http-equiv="description" content="This is my page">

 

</head>

 

<body>

	恭喜你，登录成功！

</body>

</html>

好了，把项目部署到tomcat上面去，试试看

----------------------------------------------------------------------------------

------------------------------------------------------------------------------------

输入phn，123456，看看测试结果，

--------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------

奥，显示下面这个呢，是什么原因呢？嘿嘿，这是我用了md5加密，后台是直接将md5加密的字符串存在数据库中的，但是我前面在数据库直接使用的密码是123456，所以在前台输入123456经过加密后的就不对了，看下面，这是后台打印的东西，

-------------------------------------------------------------------------------------

对应数据库中的数据是这样的

-------------------------------------------------------------------------------------

所以才会报错嘛，你看我试试输入用户名123和密码123，结果就对了，如下

-------------------------------------------------------------------------------------

好啦，项目搭建就成功了，这里就到此为止了，睡觉！

剩下的坑就明天再填啦，记得再来哦，欢迎大家一起讨论哦
