一、项目简述
功能： 用户分为患者，医生，管理员，患者可进行注册选择医生 挂号，选择日期，选择号源，医生可进行接诊，管理员可 对用户，医生信息的维护等等功能。
二、项目运行
环境配置： jdk1.8 + tomcat8.5 + mysql + eclispe (intellij idea,eclispe,myeclispe,sts 都支持)
项目技术： jdbc+ servlert + jsp + css + javascript + jquery + ajax + fileupload等等。
登录拦截器代码：
/**
* 登录拦截器
* @author administrator
*
*/
@component
public class logininterceptor implements handlerinterceptor{
private logger log = loggerfactory.getlogger(logininterceptor.class);
@autowired
private siteconfig siteconfig;
@override
public boolean prehandle(httpservletrequest request, httpservletresponse response, object handler){
string requesturi = request.getrequesturi();
httpsession session = request.getsession();
session.setattribute(sessionconstant.session_user_auth_key, appconfig.order_auth);
object attribute = session.getattribute(sessionconstant.session_user_login_key);
if(attribute == null){
log.info("用户还未登录或者session失效,重定向到登录页面,当前url=" + requesturi);
//首先判断是否是ajax请求
if(stringutil.isajax(request)){
//表示是ajax请求
try {
response.setcharacterencoding("utf-8");
response.getwriter().write(json.tojsonstring(codemsg.user_session_expired));
} catch (ioexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
return false;
}
//说明是普通的请求，可直接重定向到登录页面
//用户还未登录或者session失效,重定向到登录页面
try {
response.sendredirect("/system/login");
} catch (ioexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
return false;
}
log.info("该请求符合登录要求，放行" + requesturi);
if(!stringutil.isajax(request)){
//若不是ajax请求，则将菜单信息放入页面模板变量
user user = (user)attribute;
list<menu> authorities = user.getrole().getauthorities();
request.setattribute("usertopmenus", menuutil.gettopmenus(authorities));
list<menu> secondmenus = menuutil.getsecondmenus(user.getrole().getauthorities());
request.setattribute("usersecondmenus", secondmenus);
request.setattribute("userthirdmenus", menuutil.getchildren(menuutil.getmenuidbyurl(requesturi,secondmenus),authorities));
request.setattribute("sitename", siteconfig.getsitename());
request.setattribute("siteurl", siteconfig.getsiteurl());
}
return true;
}
}
