3, Partial code design
3.1. Save and modify personal information
The code is as follows (example):
/**
* @Title: saveAdmin
* @Description: Save and modify personal information
* @return String
*/
@RequestMapping(value="admin/Admin_saveAdmin.action",method=RequestMethod.POST)
public String saveAdmin(User paramsUser,
ModelMap model,HttpServletRequest request,HttpServletResponse response,HttpSession httpSession){
try {
//Verify that the user session has failed
if (!validateAdmin(httpSession)) {
return "loginTip";
}
//Save and modify personal information
adminManager.updateUser(paramsUser);
//Update session
User admin = new User();
admin.setUser_id(paramsUser.getUser_id());
admin = adminManager.queryUser(admin);
httpSession.setAttribute("admin", admin);
setSuccessTip("Edit succeeded", "modifyInfo.jsp", model);
} catch (Exception e) {
e.printStackTrace();
setErrorTip("Edit exception", "modifyInfo.jsp", model);
}
return "infoTip";
}
3.2. Query owner
/**
* @Title: listUsers
* @Description: Query owner
* @return String
*/
@RequestMapping(value="admin/Admin_listUsers.action")
public String listUsers(User paramsUser,PaperUtil paperUtil,
ModelMap model,HttpServletRequest request,HttpServletResponse response,HttpSession httpSession){
try {
if (paramsUser==null) {
paramsUser = new User();
}
if (paperUtil==null) {
paperUtil = new PaperUtil();
}
//Set paging information
paperUtil.setPagination(paramsUser);
//Total number of
int[] sum={0};
//Query owner list
paramsUser.setUser_type(1);
List<User> users = adminManager.listUsers(paramsUser,sum);
model.addAttribute("users", users);
model.addAttribute("paramsUser", paramsUser);
paperUtil.setTotalCount(sum[0]);
//Consult the house dictionary
Room room = new Room();
room.setStart(-1);
List<Room> rooms = adminManager.listRooms(room, null);
if (rooms==null) {
rooms = new ArrayList<Room>();
}
model.addAttribute("rooms", rooms);
} catch (Exception e) {
setErrorTip("Query owner exception", "main.jsp", model);
return "infoTip";
}
return "userShow";
}
3.3. Query employee user
/**
* @Title: listWorkeruser
* @Description: Query employee user
* @return String
*/
@RequestMapping(value="admin/Admin_listWorkeruser.action")
public String listWorkeruser(User paramsUser,PaperUtil paperUtil,
ModelMap model,HttpServletRequest request,HttpServletResponse response,HttpSession httpSession){
try {
if (paramsUser==null) {
paramsUser = new User();
}
if (paperUtil==null) {
paperUtil = new PaperUtil();
}
//Set paging information
paperUtil.setPagination(paramsUser);
//Total number of
int[] sum={0};
//Query employee user list
paramsUser.setUser_type(3);
List<User> users = adminManager.listWorkerusers(paramsUser,sum);
model.addAttribute("users", users);
model.addAttribute("paramsUser", paramsUser);
paperUtil.setTotalCount(sum[0]);
//Consult the house dictionary
Room room = new Room();
room.setStart(-1);
List<Room> rooms = adminManager.listRooms(room, null);
if (rooms==null) {
rooms = new ArrayList<Room>();
}
model.addAttribute("rooms", rooms);
} catch (Exception e) {
setErrorTip("Query employee user exception", "main.jsp", model);
return "infoTip";
}
return "workeruserShow";
}
