Maven搭建Springmvc+Spring+Hibernate+html

最近在学前端，由于之前是干Android和Java所以顺便就搞搞Web的东西。于是就摸索了用Maven搭建Springmvc+Spring+Hibernate+html的工程，废话不多说。
工具：Eclipse-Neon.1 Release RC3 (4.6.1RC3)
Maven3.3.9
首先是来创建Maven工程：

单击File->New->Maven Project，选择红框中的第二个选项，这个选项可以引用Maven的骨架。

在这一步我们选择webapp这个选项来创建我们的web工程。

最后一步就是要填写group id和artifact id，其中Package也默认是group id的值。
创建好的工程目录结构：

工程创建完毕，接下来就开始搭建工程，我们选择用JavaEE框架时，第一件事情就是找jar包，而Maven最大的方便之处就是解决了jar包的问题。我们只需要在pom.xml文件中配置所需的jar包即可。

</project>

这个就是pom的全配置，同时还列出了几个Maven的远程仓库。国内的网络就不提了。有时候当一些仓库连接不通畅时下载jar包就会奇慢无比。所以多试几个地址还是有好处的。
当然下载jar包还有一种方法就是用命令行到工程目录然后执行mvn clean install -U就可以下载jar包了。
jar包搞定的就是JavaEE框架的配置文件了，这里不在赘述。配置如下：

</web-app>

至此，配置文件已全部完成。接下来就可以编写代码了。使用框架的好处就是可以相互解耦，层次分明。所以分包时根据相应的名字来命名包。
首先是实体类：UserEntity.java这里采用了注解。所以要注意@column中name的属性要和数据库中的列名一样。

package com.ls.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 ls*/
@Table(name="custom")
@Entity
public class UserEntity {private int id;private String name;private String account;private String password;private String sex; private String phone;@Id@GeneratedValue(strategy = GenerationType.IDENTITY)@Column(name = "UID", nullable = false, length = 11)public int getId() {return id;}public void setId(int id) {this.id = id;}@Column(name = "UNAME", nullable = false, length = 20)public String getName() {return name;}public void setName(String name) {this.name = name;}@Column(name = "UACCOUNT", nullable = false, length = 20)public String getAccount() {return account;}public void setAccount(String account) {this.account = account;}@Column(name = "UPASSWORD", nullable = false, length = 20)public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}@Column(name = "USEX", nullable = false, length = 4)public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}@Column(name = "UPHONE", nullable = false, length = 15)public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}
}

接下来是dao层，一个接口一个实现的类
接口UserDao.java

package com.ls.dao;
import com.ls.model.UserEntity;
/*** @author ls*/
public interface IUserDao {public boolean isExist(UserEntity user);
}

UserDaoImpl.java

package com.ls.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.ls.dao.IUserDao;
import com.ls.model.UserEntity;/*** @author ls*/@Repository("userDao")
public class UserDaoImpl implements IUserDao {@Resourceprotected SessionFactory sessionFactory;public Session getSession() {return sessionFactory.getCurrentSession();}public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}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.getAccount());query.setString(1, user.getPassword());if (query.list().size() >= 1) {return true;}return false;}
}

然后是service层，同样是一个接口，一个实现类
接口UserService.java

package com.ls.service;
import com.ls.model.UserEntity;
/*** @author ls*/
public interface UserService {public boolean isExist(UserEntity user);
}

UserServiceImpl.java

package com.ls.service.impl;import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.ls.dao.IUserDao;
import com.ls.model.UserEntity;
import com.ls.service.IUserService;
/*** @author ls*/
@Transactional
@Service("userService")
public class UserServiceImpl implements IUserService {@Resourceprivate IUserDao userDao;@Overridepublic boolean isExist(UserEntity user) {return userDao.isExist(user);}
}

最后就是控制层了
UserController.java

package com.ls.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.ls.model.UserEntity;
import com.ls.service.IUserService;/*** @author ls*/
@Controller
@RequestMapping("/user")
public class UserController{@Resourceprivate 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;}
}

然后就是View层。是html+js实现的一个简单的登录页面。
login.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>登录</title>
<meta charset="utf-8">
<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="../css/login.css">
<script type="text/javascript" src="../js/jquery-1.8.2.min.js"></script>
<script type="text/javascript" src="../js/md5.js"></script>
<script type="text/javascript" src="../js/login.js"></script>
</head>
<body><div>UserName:<input type="text" name="account" /> <br/>PassWord:<input type="password" name="password" /><br/> <input type="submit" id="loginBtn" value="Login" /></div>
</body>
</html>

$(function() {$("#loginBtn").click(function() {console.log("login");var account = $("input[name=account]").val();var password = $("input[name=password]").val();var user = {"account" : account,"password" : password};$.ajax({type : "post",dataType : "json",data : user,contentType : "application/x-www-form-urlencoded;charset=UTF-8",url : "http://localhost:8080/LSProject/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+"/LSProject/"+"html/index.html";window.location = indexUrl;}},error : function() {alert("服务器发生故障，请尝试重新登录！");}});});
});

至此整个工程搭建完毕。

小结：可能遇到的问题，在我搭建工程的时候，由于网络问题导致下载的jar包有问题，使我的工程一直跑不起来。具体的报错就是Tomcat的组件无法启动成功，遇到类似问题时可以检查一下jar是否完整。还有就是MySql数据库的信息配置，这个要配置正确。
