java分析页面登陆逻辑
1、@Controller
@RequestMapping(value = "/admin/user")
public class UserController {
private static final Logger logger = LoggerFactory.getLogger(UserController.class);
@Autowired
private IUserService userService;
@Autowired
private IRoleService roleService;
2、 @RequestMapping(value = "/list/{pageNo}",method = RequestMethod.GET)
public String list(Model model,@PathVariable("pageNo")Long pageNo){
Long count =userService.getCount(null).longValue();
Page page = new Page(pageNo,count);
List<User>lists = userService.findList(page);
model.addAttribute("list",lists);
model.addAttribute("page",page);
return "user/list";
}
3、 /**
* 跳转到添加用户的页面
* @param model
* @return
*/
@RequestMapping(value = "/add",method = RequestMethod.GET)
public String add(Model model){
logger.debug("跳转到添加用户的页面");
model.addAttribute("user",new User());
model.addAttribute("roles",roleService.list());
return "user/add";
}
1、 /**
* 添加用户保存的方法
* @param user
* @param request
* @return
*/
@RequestMapping(value = "/add",method = RequestMethod.POST)
public String add(User user, HttpServletRequest request){

roleIdList.add(Integer.parseInt(roleId));
}
userService.add(user,roleIdList);
// 重定向到本 Controller 的 list 方法（Get 方式）
return "redirect:list/1";
}
2、 @ResponseBody
@RequestMapping(value = "/updateStatus",method = RequestMethod.POST)
public Map<String,Object> updateStatus(User user){
User u = userService.update(user);
Map<String,Object> result = new HashMap<>();
if(u != null){

* @param model
* @return
*/
@RequestMapping(value = "/update/{id}",method = RequestMethod.GET)

* 将用户的所有角色 id 添加到一个字符串中
*/

// 指定用户拥有的角色信息
model.addAttribute("hasRole", rids);
return "user/update";

/**
* 更新用户的信息（包括更新用户绑定的角色）
* @param user
* @return
*/
@RequestMapping(value = "/update/{id}",method = RequestMethod.POST)
public String update(User user,HttpServletRequest request,String[] newPassword,Model model){
// // TODO: 2016/9/18 这个过程还是可以优化的，如果属性没有发生变化的地方，是不须要更新的
logger.debug("user => " + user);
if(newPassword[0].equals(newPassword[1])){

String[] roleIds = request.getParameterValues("roleId");

return "redirect:/admin/user/list/1";
}else{
model.addAttribute("msg", "密码不一致");
return "redirect:/admin/user/update/"+user.getId();
}
}
4、 /**
* 根据用户 id 跳转到用户权限的列表页面
* @return
*/
@RequestMapping(value = "/resources/{id}",method = RequestMethod.GET)
public String listResources(@PathVariable("id") Integer userId,Model model){
List<Resource> resourceList = userService.listAllResource(userId);
User user = userService.load(userId);

return "user/resources";
}
/**
* 批量删除用户
* 1、删除用户数据
* 2、删除用户绑定的角色数据
* @param userIds
* @return
*/
@ResponseBody
@RequestMapping(value = "/delete",method = RequestMethod.POST)
public Map<String,Object> delete(
@RequestParam("userIds[]") List<Integer> userIds){
