【struts2+hibernate+spring项目实战】实现用户登录功能（ssh）
小编觉得挺不错的,现在分享给大家,帮大家做个参考.
一、概述
从今天才开始有时间来总结总结以前自己练习的一些东西，希望总结出来对以后可以更加便捷的来学习，也希望可以帮助到正需要这些东西的同行人，一起学习，共同进步。
二、 登录功能总结
2.1、登录功能概述
这个技术主要是运用Struts2+hibernate+spring的技术来进行登录功能的实现的，并且是在一个具体的项目中来实现的，对于以后的借鉴能够提供便捷。
2.2、具体实现
2.2.1、登录页面的实现
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link href="css/index.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="js/jquery-1.8.3.js"></script> <title>赣师大qualitycontrol-系统登录页</title> <script>$(function() {$("#login_ok").click(function() {$("form:first").submit();});});function MM_swapImage(srcObj,image_src){srcObj.src=image_src;} </script> </head> <body><s:actionerror/><div class="container-login"><div class="login-pic"><div class="login-text"><s:form action="emp_login" method="post"><table width="100%" border="0" cellpadding="0" cellspacing="0"><tr><td width="19%" height="28">用户名：</td><td colspan="2"><s:textfield name="em.userName" size="18" value="admin"/></td></tr><tr><td height="31">密 码：</td><td colspan="2"><s:textfield name="em.pwd" size="18" value="admin"/></td></tr><tr><td height="30">验证码：</td><td width="43%"><input type="text" size="9" /></td><td width="32%"><img src="images/test.gif" /></td></tr><tr><td height="30"> </td><td colspan="2"><a href="javascript:void(0)" id="login_ok"><img src="images/denglu_bg_03.gif" name="Image1" width="40" height="22" border="0" onmouseover="MM_swapImage(this,'images/denglu_h_03.gif')" onmouseout="MM_swapImage(this,'images/denglu_bg_03.gif')" /></a><a href="#"><img src="images/giveup_bg_03.gif" name="Image2" width="42" height="22" border="0" onmouseover="MM_swapImage(this,'images/giveup_h_03.gif')" onmouseout="MM_swapImage(this,'images/giveup_bg_03.gif')" /></a></td></tr></table></s:form></div></div></div> </body> </html>在这里的一部分，主要是页面的回显和验证码的显示s:textfield name="em.userName" size="18" value="admin"/>。
2.2.2、action的实现
//登录public String login(){HttpServletRequest request = getRequest();String loginIp = request.getHeader("x-forwarded-for"); if(loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getHeader("Proxy-Client-IP"); } if(loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getHeader("WL-Proxy-Client-IP"); } if(loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getRemoteAddr(); }EmpModel loginEm = empEbi.login(em.getUserName(),em.getPwd(),loginIp);if(loginEm == null){this.addActionError("对不起，用户名密码错误！");return "loginFail";}else{//在登录成功的时候，查询该用户的所有权限List<ResModel> resList = resEbi.getResByEm(loginEm.getUuid());StringBuilder sbf = new StringBuilder();for (ResModel rm : resList) {sbf.append(rm.getText());sbf.append(",");} // System.out.println("11111111111111"); // System.out.println(sbf.toString()+"=="+loginEm.getUuid()); // System.out.println("11111111111111");loginEm.setResAll(sbf.toString());putSession(EmpModel.EMP_LOGIN_USER_OBJECT_NAME, loginEm);return "loginSuccess";}}2.2.3、service实现
public EmpModel login(String userName, String pwd,String lastLoginIp) {//MD5加密pwd = MD5Utils.md5(pwd);//调用数据层EmpModel loginEm = empDao.getByUserNameAndPwd(userName,pwd);if(loginEm != null){//登录成功//添加登录信息//登录次数+1loginEm.setLoginTimes(loginEm.getLoginTimes()+1);//最后登录时间loginEm.setLastLoginTime(System.currentTimeMillis());//最后登录IPloginEm.setLastLoginIp(lastLoginIp);//快照更新}return loginEm;}2.2.4、dao的实现
dao主要是通过用户名和密码来查询这个用户是否存在
2.2.5、用户实体类
package org.sihai.qualitycontrol.auth.emp.vo;import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Date; import java.util.HashMap; import java.util.Map; import java.util.Set;import org.sihai.qualitycontrol.auth.dep.vo.DepModel; import org.sihai.qualitycontrol.auth.role.vo.RoleModel; import org.sihai.qualitycontrol.util.format.FormatUtil;public class EmpModel {public static final String EMP_LOGIN_USER_OBJECT_NAME = "loginEm";//数据结构思想应用public static final Integer EMP_GENDER_OF_MAN = 1;public static final Integer EMP_GENDER_OF_WOMAN = 0;public static final String EMP_GENDER_OF_MAN_VIEW = "男";public static final String EMP_GENDER_OF_WOMAN_VIEW = "女";public static final Map<Integer, String> genderMap = new HashMap<Integer, String>();static{genderMap.put(EMP_GENDER_OF_MAN, EMP_GENDER_OF_MAN_VIEW);genderMap.put(EMP_GENDER_OF_WOMAN, EMP_GENDER_OF_WOMAN_VIEW);}private Long uuid;private String userName;private String name;private String pwd;private String email;private String tele;private String address;private String lastLoginIp;private Integer loginTimes;private Long lastLoginTime;private Integer gender;private String resAll;public String getResAll() {return resAll;}public void setResAll(String resAll) {this.resAll = resAll;}/*//Long:记录的是毫秒值 //Date:对long的包装 优点：格式好，缺点：计算时间略有复杂性现在的时间是2020年4月31日180天前是几号？现在的long System.currentTimeMillis()-180*24*60*60*1000long-long >0Date 2014年1月4日 14：21Date 2014年1月4日 14：22 */private Long birthday;private Set<RoleModel> roles;//多对多public Set<RoleModel> getRoles() {return roles;}public void setRoles(Set<RoleModel> roles) {this.roles = roles;}//视图值：视图值是一种用于界面显示的变量值，该值不具体对应某个数据库字段，它服务于某个数据库字段//当数据库中的某个字段值不便于直接显示时，为该字段添加视图值，用于显示对应的信息//1.定义一个String类型的变量，变量名是无法合理显示的字段的字段名+View//2.提供其get方法//3.在其对应的变量的set方法中对这个View值进行初始化private String birthdayView;private String genderView;private String lastLoginTimeView;public String getLastLoginTimeView() {return lastLoginTimeView;}public String getLastLoginIp() {return lastLoginIp;}public void setLastLoginIp(String lastLoginIp) {this.lastLoginIp = lastLoginIp;}public Integer getLoginTimes() {return loginTimes;}public void setLoginTimes(Integer loginTimes) {this.loginTimes = loginTimes;}public Long getLastLoginTime() {return lastLoginTime;}public void setLastLoginTime(Long lastLoginTime) {this.lastLoginTime = lastLoginTime;this.lastLoginTimeView = FormatUtil.formatDate(lastLoginTime);}public String getGenderView() {return genderView;}public String getBirthdayView() {return birthdayView;}//多对一private DepModel dm;public Long getUuid() {return uuid;}public void setUuid(Long uuid) {this.uuid = uuid;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}public String getTele() {return tele;}public void setTele(String tele) {this.tele = tele;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}public Integer getGender() {return gender;}public void setGender(Integer gender) {this.gender = gender;this.genderView = genderMap.get(gender);}public Long getBirthday() {return birthday;}public void setBirthday(Long birthday) {this.birthday = birthday;this.birthdayView = FormatUtil.formatDate(birthday);}public DepModel getDm() {return dm;}public void setDm(DepModel dm) {this.dm = dm;}}2.2.5.1、视图值的用法
在实体类中通过对数据的转化成页面需要显示的形式到页面来显示。
实体类中：
private String genderView; //数据结构思想应用public static final Integer EMP_GENDER_OF_MAN = 1;public static final Integer EMP_GENDER_OF_WOMAN = 0;public static final String EMP_GENDER_OF_MAN_VIEW = "男";public static final String EMP_GENDER_OF_WOMAN_VIEW = "女";public static final Map<Integer, String> genderMap = new HashMap<Integer, String>();static{genderMap.put(EMP_GENDER_OF_MAN, EMP_GENDER_OF_MAN_VIEW);genderMap.put(EMP_GENDER_OF_WOMAN, EMP_GENDER_OF_WOMAN_VIEW);}//通过set方法，把性别的原本的0/1，转为男或女在页面显示public void setGender(Integer gender) {this.gender = gender;this.genderView = genderMap.get(gender);}页面显示：
${genderView}2.2.5.2、Struts2中对map的取值
<s:select name="eqm.gender" list="@org.sihai.qualitycontrol.auth.emp.vo.EmpModel@genderMap" cssStyle="width:190px" headerKey="-1" headerValue="----请-选-择----"></s:select>这里的list的取值首先用额是Struts2的标签，然后运用ognl表达式来在页面上对map取值。
2.2.5.3、Struts2中对list的取值
<s:select name="eqm.dm.uuid" list="depList" listKey="uuid" listValue="name" cssStyle="width:190px" headerKey="-1" headerValue="----请-选-择----"></s:select>总结
