spring springmvc hibernate(ssh)项目整合开发---总体架构搭建
国庆觉得没啥地方想去，于是乎想自己搭建一个长期的用于练手的ssh项目（注意：这里的ssh指的是spring4 springmvc4 hibernate4），在其中融进自己学到的技术，并持续进行更新，与诸位博友共享。目前开发了一个在web项目中比较实用的邮件通信工具类，其中在这个ssh项目中主要用于：“注册成功时采用邮箱验证”与“忘记密码时通过邮件找回密码”。我觉得两个是比较实用的小模块。
好了，废话不多说，在介绍上述的两个小模块之前，毫无疑问的，得先把项目的整体架构搭建起来！项目的后端架构采用spring4 springmvc4 hibernate4，前端采用jsp、jquery、ajax。
首先先预览一下项目的总体架构图：
放入jar包，可以到这里下载：ssm整合jar包
接下来，配置web.xml，如下所示：
<?xml version="1.0" encoding="UTF-8"?>spring的配置文件：（已在xml文件中进行详细的注释，不多说明）

然后，建立com.steadyjack.server.dao、com.steadyjack.server.dao.impl这两个package，并在impl包创建BaseDaoImpl.java文件，用于获取hibernate的sessionFactory，以便给各个dao通用。
package com.steadyjack.server.dao.impl;在 com.steadyjack.server.model包下建立 User 这个Model
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
@Repository
public class BaseDaoImpl{
@Autowired
private SessionFactory sessionFactory;
public Session getSession(){
return sessionFactory.getCurrentSession();
}
}
package com.steadyjack.server.model;在com.steadyjack.server.dao建立UserDao以及在 com.steadyjack.server.dao.impl建立UserDaoImpl
import java.io.Serializable;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="tb_user")
public class User implements Serializable{
/**

private static final long serialVersionUID = -5813264827007873950L;
private Integer id;
private String userName;

//是否已经被验证：0表示未验证 1表示已经验证
private Integer isValidated=0;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@Column(name="user_name")
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getSex() {
return sex;
}
public void setSex(Integer sex) {
this.sex = sex;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Column(name="validate_ser_code")
public String getValidateSerCode() {
return validateSerCode;
}
public void setValidateSerCode(String validateSerCode) {
this.validateSerCode = validateSerCode;
}
@Column(name="validate_over_date")
public Date getValidateOverDate() {
return validateOverDate;
}
public void setValidateOverDate(Date validateOverDate) {
this.validateOverDate = validateOverDate;
}
@Column(name="user_name_encodes")
public String getUserNameEncodes() {
return userNameEncodes;
}
@Column(name="is_validated")
public Integer getIsValidated() {
return isValidated;
}
public void setIsValidated(Integer isValidated) {
this.isValidated = isValidated;
}
public void setUserNameEncodes(String userNameEncodes) {
this.userNameEncodes = userNameEncodes;
}
@Override
public String toString() {
return "User [id=" + id + ", userName=" + userName + ", password="
+ password + ", email=" + email + ", sex=" + sex + "]";
}
}
package com.steadyjack.server.dao;
import java.util.List;
import com.steadyjack.server.model.User;
public interface UserDao {
public void saveUser(User user);
public User queryUser(User user);
public User findUserById(Integer id);
public User findUserPassword(String userName,String email);
public List<User> findUser(List<Object> params,String hql);
public void updateUser(User user);
public User findUserByUserName(String userName);
}
package com.steadyjack.server.dao.impl;import java.util.List;import org.hibernate.Query;import org.springframework.stereotype.Repository;import com.steadyjack.server.dao.UserDao;import com.steadyjack.server.model.User;@Repositorypublic class UserDaoImpl extends BaseDaoImpl implements UserDao { @SuppressWarnings("unchecked") public User queryUser(User user) { String hql="from User where userName=? and password=?"; Query query=getSession().createQuery(hql); query.setParameter(0, user.getUserName()); query.setParameter(1, user.getPassword()); User currentUser=null; List<User> userList=query.list(); if (userList!=null && userList.size()>0) { currentUser=userList.get(0); } return currentUser; } public void saveUser(User user) { getSession().save(user); } public User findUserById(Integer id) { String hql="from User where id=?"; Query query=getSession().createQuery(hql); query.setParameter(0, id); User user=(User) query.uniqueResult(); return user; } public User findUserPassword(String userName, String email) { String hql="from User where userName=? and email=?"; Query query=getSession().createQuery(hql); query.setParameter(0, userName); query.setParameter(1, email); User currentUser=(User) query.uniqueResult(); return currentUser; } public void updateUser(User user) { getSession().update(user); } @SuppressWarnings("unchecked") public List<User> findUser(List<Object> params,String hql) { Query query=getSession().createQuery(hql); if (params!=null && params.size()>0) { for(int i=0;i<params.size();i++){ query.setParameter(i, params.get(i)); } } return query.list(); } public User findUserByUserName(String userName) { String hql="from User where userName=?"; Query query=getSession().createQuery(hql); query.setParameter(0, userName); return (User) query.uniqueResult(); } }
在com.steadyjack.server.service包下建立UserService以及在com.steadyjack.server.service.impl包下建立UserServiceImpl
package com.steadyjack.server.service;
import java.util.List;
import java.util.Map;
import com.steadyjack.server.model.User;
public interface UserService {
public void addUser(User user);
public User queryUser(User user);
public User getUserById(Integer id);
public User findUserPassword(String userName,String email);
public List<User> findUsers(Map<String, Object> map);
public void updateUser(User user);
public void saveUser(User user);
public User findUserByUserName(String userName);
}
package com.steadyjack.server.service.impl;import java.util.LinkedList;import java.util.List;import java.util.Map;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.steadyjack.server.dao.UserDao;import com.steadyjack.server.model.User;import com.steadyjack.server.service.UserService;@Servicepublic class UserServiceImpl implements UserService { @Autowired private UserDao userDao; public void addUser(User user) { userDao.saveUser(user); } public User queryUser(User user) { return userDao.queryUser(user); } public User getUserById(Integer id) { return userDao.findUserById(id); } public User findUserPassword(String userName, String email) { return userDao.findUserPassword(userName, email); } public void updateUser(User user) { userDao.updateUser(user); } public List<User> findUsers(Map<String, Object> map) { StringBuffer hql=new StringBuffer("from User where 1=1 "); List<Object> params=new LinkedList<Object>(); if (map.get("userName")!=null) { hql.append(" and userName=? "); params.add(map.get("userName")); } if (map.get("email")!=null) { hql.append(" and email=? "); params.add(map.get("email")); } if (map.get("sex")!=null) { hql.append(" and sex=? "); params.add(map.get("sex")); } if (map.get("validateOverDate")!=null) { hql.append(" and validateOverDate=? "); params.add(map.get("validateOverDate")); } if (map.get("validateSerCode")!=null) { hql.append(" and validateSerCode=? "); params.add(map.get("validateSerCode")); } if (map.get("userNameEncodes")!=null) { hql.append(" and userNameEncodes=? "); params.add(map.get("userNameEncodes")); } System.out.println(hql.toString()); return userDao.findUser(params, hql.toString()); } public User findUserByUserName(String userName) { return userDao.findUserByUserName(userName); } public void saveUser(User user) { userDao.saveUser(user); } }
最后，我们需要在com.steadyjack.web.controller包建立UserController（先介绍登录这个功能）
package com.steadyjack.web.controller;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.steadyjack.server.model.User;
import com.steadyjack.server.service.UserService;
import com.steadyjack.server.utils.DateUtils;
import com.steadyjack.server.utils.JavaMailUtils;
import com.steadyjack.server.utils.SystemUtils;
import com.steadyjack.server.utils.UUIDUtils;
@RequestMapping("/user")
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/index/{id}")
public String index(ModelMap map,@PathVariable Integer id){
System.out.println(userService.getUserById(id));
map.put("loginUser", userService.getUserById(id));
return "user/index";
}
@ResponseBody
@RequestMapping("/login")
public Map<String, Object> userLogin(ModelMap map,HttpServletRequest request) throws Exception{
Map<String, Object> resultMap=new HashMap<String, Object>();
User user=new User();
user.setUserName(request.getParameter("userName"));
user.setPassword(request.getParameter("password"));
User currentUser=userService.queryUser(user);
if (currentUser!=null) {
resultMap.put("id", currentUser.getId());
resultMap.put("res", "yes");
}else{
resultMap.put("res", "no");
}
return resultMap;
}
}
最后是webContent的启动jsp文件index.jsp（这里用到了jquery ajax的交互）：
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<c:set value="${pageContext.request.contextPath }" var="ctx"></c:set>
<script type="text/javascript" src="${ctx}/style/js/jquery-1.7.2.min.js"></script>
<title>用户登录</title>
<script type="text/javascript">
$(function(){
var serverUrl=$('#serverUrl').val();
$('#loginBtn').click(function(){
var userName = $('#userName').val();
var password = $('#password').val();
if (userName == null || password == null || trim(userName) == "" || trim(password) == "") {
$('#errorTip').html("用户名或密码不能为空!");
return false;
}
$('#errorTip').html("");
$.post(serverUrl+'/user/login',{
userName:userName,
password:password
},function(requestData){
if (requestData.res=='yes') {
window.location.href=serverUrl+'/user/index/'+parseInt(requestData.id);
} else {
$('#errorInfo').html('*用户名或者密码错误!');
}
});
});
});
function resetValue() {
$('#userName').val("");
$('#password').val("");
}
//去掉最后的空格
function trim(str) {
return str.replace(/(^\s+)|(\s+$)/g, "");
}
</script>
</head>
<body>
<input type="hidden" id="serverUrl" value="${pageContext.request.contextPath}" />
<div align="center" style="padding-top: 50px;">
<form>
<table>
<tr>
<td>用户名：</td>

</table>
<div id="errorTip"></div>
</form>
<a href="${ctx}/user/forgetPassword">忘记密码</a> <a href="${ctx}/user/toRegister">用户注册</a>

</body>
</html>
右键项目，run 到tomcat，跑起来。如果没有报错，说明启动成功了！然后我们需要在我们的数据库录入用户的信息，测试登录功能。如下图：
好了，初步就先介绍到这里吧，明天介绍博文开篇提到的两个小模块！
