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。

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：

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 {
@Resource
protected 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 {
@Resource
private IUserDao userDao;
@Override
public 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{
@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;
}
}

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">

<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>

login.js其中遇到了一个问题就是html中请求数据，url要写全

$(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。
