篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了javaWeb校园宿舍管理解析相关的知识，希望对你有一定的参考价值。
前两章主要集成Struts2以及mybatis，并进行的相应的小测试，现在我们来实现整个登录功能，说简单一下，登录功能就是登录页-->发送请求-->action-->dao-->主菜单。
Struts2做为一个声明性架构，struts.xml作为他的入口，用来定义动作默认地方，很多企业习惯将功能模块化，然后在引入struts.xml，因为我们这个项目比较简单，我就不模块化了，所有动作都定义在struts.xml中。
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="strutsqs" extends="struts-default" namespace="/" > <action name="GoLogin" class="com.action.GoLogin"> <result name="input">/Login.jsp</result> <result name="success">/Index.jsp</result> </action> </package> </struts>
Struts2中的Action采用了低侵入式的设计，Struts2不要求Action类继承任何的Struts2的基类或实现Struts2接口。(但是，我们为了方便实现Action，大多数情况下都会继承com.opensymphony.xwork2.ActionSupport类，并重写此类里的public String execute() throws Exception方法。因为此类中实现了很多的实用接口，提供了很多默认方法，这些默认方法包括获取国际化信息的方法、数据校验的方法、默认的处理用户请求的方法等，这样可以大大的简化Action的开发。)
Struts2中通常直接使用Action来封装HTTP请求参数，因此，Action类里还应该包含与请求参数对应的属性，并且为属性提供对应的getter和setter方法。(当然，Action类中还可以封装处理结果，把处理结果信息当作一属性，提供对应的getter和setter方法)。
登录核心action类，用来根据登录人类型不同进行不同的判断。
package com.Action;
import javax.servlet.http.HttpSession;
import org.apache.struts2.ServletActionContext;
import com.bean.AdminBean;
import com.dao.AdminDao;
import com.dao.impl.AdminDaoImpl;
import com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings("serial")
public class GoLogin extends ActionSupport{
private String Type;
private String Username;
private String Password;
private String Msg;
public String getType() {
return Type;
}
public void setType(String type) {
Type = type;
}
public String getUsername() {
return Username;
}
public void setUsername(String username) {
Username = username;
}
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
public String getMsg() {
return Msg;
}
public void setMsg(String msg) {
Msg = msg;
}
public String execute() throws Exception {
if(Type.equals("系统管理员"))
{
AdminBean admin=new AdminBean();
admin.setAdmin_Name(Username);
admin.setAdmin_Password(Password);
AdminDao dao=new AdminDaoImpl();
if (dao.CheckLogin(admin)==null) {
Msg = "用户名或者密码错误";
return INPUT;
}
else
{
//获取ID
String Admin_ID=dao.CheckLogin(admin);
//创建session
HttpSession session = ServletActionContext.getRequest().getSession();
session.setAttribute("id", Admin_ID);
session.setAttribute("type", "1");
return SUCCESS;
}
}else
{
Msg = "身份类型错误";
return INPUT;
}
}
}将Login.jsp中的form action属性修改为
<form name="form1" action="GoLogin.action" method="post" onSubmit="return mycheck()">
加入Index.jsp以及Left.jsp,这两个页面加入后，运行项目输入zhangsan/123,这是我们就可以进入主页面了，项目非常简单的权限控制，从账号、角色以及角色权限都是清一色的固定，不要小看简单的项目，往往一个项目的搭建都是从简至繁。

</table>下面我们来看看输入正确的账号后进入的主页：
以上已经完成管理员的初步，现在我们分别创建楼宇管理者以及学生类型的验证，同admin一样，先建表，创建实体类，创建mybatis映射文件然后创建dao并在登录的action中添加楼宇管理者以及学生类型的判断操作，大致如下：
create table TEACHER ( teacher_id NUMBER, teacher_username VARCHAR2(20), teacher_password VARCHAR2(20), teacher_name VARCHAR2(20), teacher_sex VARCHAR2(10), teacher_tel VARCHAR2(20) )
create table STUDENT ( student_id NUMBER, student_username VARCHAR2(20), student_password VARCHAR2(20), student_name VARCHAR2(20), student_sex VARCHAR2(10), student_tel VARCHAR2(20) )
创建实体类：
package com.bean;
public class TeacherBean {
private int Teacher_ID ;
private String Teacher_Username ;
private String Teacher_Password ;
private String Teacher_Name ;
private String Teacher_Sex ;
private String Teacher_Tel ;
public int getTeacher_ID() {
return Teacher_ID;
}
public void setTeacher_ID(int teacherID) {
Teacher_ID = teacherID;
}
public String getTeacher_Username() {
return Teacher_Username;
}
public void setTeacher_Username(String teacherUsername) {
Teacher_Username = teacherUsername;
}
public String getTeacher_Password() {
return Teacher_Password;
}
public void setTeacher_Password(String teacherPassword) {
Teacher_Password = teacherPassword;
}
public String getTeacher_Name() {
return Teacher_Name;
}
public void setTeacher_Name(String teacherName) {
Teacher_Name = teacherName;
}
public String getTeacher_Sex() {
return Teacher_Sex;
}
public void setTeacher_Sex(String teacherSex) {
Teacher_Sex = teacherSex;
}
public String getTeacher_Tel() {
return Teacher_Tel;
}
public void setTeacher_Tel(String teacherTel) {
Teacher_Tel = teacherTel;
}
}package com.bean;
public class StudentBean {
private int Student_ID ;
private int Student_DomitoryID ;
private String Student_Username ;
private String Student_Password ;
private String Student_Name ;
private String Student_Sex ;
private String Student_Class ;
private String Student_State ;
public int getStudent_ID() {
return Student_ID;
}
public void setStudent_ID(int studentID) {
Student_ID = studentID;
}
public int getStudent_DomitoryID() {
return Student_DomitoryID;
}
public void setStudent_DomitoryID(int studentDomitoryID) {
Student_DomitoryID = studentDomitoryID;
}
public String getStudent_Username() {
return Student_Username;
}
public void setStudent_Username(String studentUsername) {
Student_Username = studentUsername;
}
public String getStudent_Password() {
return Student_Password;
}
public void setStudent_Password(String studentPassword) {
Student_Password = studentPassword;
}
public String getStudent_Name() {
return Student_Name;
}
public void setStudent_Name(String studentName) {
Student_Name = studentName;
}
public String getStudent_Sex() {
return Student_Sex;
}
public void setStudent_Sex(String studentSex) {
Student_Sex = studentSex;
}
public String getStudent_Class() {
return Student_Class;
}
public void setStudent_Class(String studentClass) {
Student_Class = studentClass;
}
public String getStudent_State() {
return Student_State;
}
public void setStudent_State(String studentState) {
Student_State = studentState;
}
private String Domitory_Name ;
private String Building_Name ;
public String getDomitory_Name() {
return Domitory_Name;
}
public void setDomitory_Name(String domitoryName) {
Domitory_Name = domitoryName;
}
public String getBuilding_Name() {
return Building_Name;
}
public void setBuilding_Name(String buildingName) {
Building_Name = buildingName;
}
private String Domitory_Type ;
private String Domitory_Number ;
private String Domitory_Tel ;
public String getDomitory_Type() {
return Domitory_Type;
}
public void setDomitory_Type(String domitoryType) {
Domitory_Type = domitoryType;
}
public String getDomitory_Number() {
return Domitory_Number;
}
public void setDomitory_Number(String domitoryNumber) {
Domitory_Number = domitoryNumber;
}
public String getDomitory_Tel() {
return Domitory_Tel;
}
public void setDomitory_Tel(String domitoryTel) {
Domitory_Tel = domitoryTel;
}
}创建mybatis映射关系

}修改登录action--GoLogin.java，增加身份类型为学生、楼宇管理员的if条件判断。

}数据库插入测试数据：
insert into Student (STUDENT_ID, STUDENT_USERNAME, STUDENT_PASSWORD, STUDENT_NAME, STUDENT_SEX, STUDENT_TEL) values (1, ‘wangwu‘, ‘123‘, ‘王五‘, ‘男‘, ‘159*********‘);
insert into Teacher (TEACHER_ID, TEACHER_USERNAME, TEACHER_PASSWORD, TEACHER_NAME, TEACHER_SEX, TEACHER_TEL) values (1, ‘lisi‘, ‘123‘, ‘李四‘, ‘女‘, ‘159**********‘);
现在我们根据不同身份输入不同账号，可有查看各个账号有不同的权限，这种权限控制在页面根据身份判断写死，在企业中是不可能出现的，非常不利于维护以及安全问题，在这里我只是解析网上这款项目的代码，业务以及逻辑方面暂不改动，适合新手来自己搭建一款项目。
