嗨，我在重定向期间收到下一个错误：
The request sent by the client was syntactically incorrect
浏览器显示的URL是：localhost：8080 / Project / menu / main / home / 0，这里我的类重定向首先 – “从”，第二个“到”：
/*
* Get all possible values of menu and generate correct url to pages controllers
*
*/
@Controller
@SessionAttributes("menu")
public class MainMenuController {
@ModelAttribute
public Menu createMenu() {
return new Menu();
}
@RequestMapping(value = "/menu", method = RequestMethod.GET)
public String mainMenuResolver(@ModelAttribute Menu menu) {
menu.setMainMenu("first");
return "forward:/menu/first";
}
@RequestMapping(value = "/menu/{mainMenu}", method = RequestMethod.GET)
public String subMenuResolver(@PathVariable String mainMenu, @ModelAttribute Menu menu) {
menu.setMainMenu(mainMenu);
menu.setSubMenu("home");
return "forward:/menu/first/home";
}
@RequestMapping(value = "/menu/{mainMenu}/{subMenu}", method = RequestMethod.GET)
public String secMenuResolver(@PathVariable String mainMenu, @PathVariable String subMenu, @ModelAttribute Menu menu) {
menu.setMainMenu(mainMenu);
menu.setSubMenu(subMenu);
menu.setSecMenu("0");
if (menu.getMainMenu().equals("first")){
return "redirect:/menu/main/"+menu.getSubMenu()+"/"+menu.getSecMenu();
}
if (menu.getMainMenu().equals("second")){
return "redirect:/menu/religion/"+menu.getSubMenu()+"/"+menu.getSecMenu();
}
return "redirect:/menu/main/"+menu.getSubMenu()+"/"+menu.getSecMenu();
}
}
二等：
@Controller
@SessionAttributes("menu")
public class FirstPageController {
@ModelAttribute
public Menu createMenu() {
return new Menu();
}
@RequestMapping(value = "/menu/main/{subMenu}/{secMenu}", method = RequestMethod.GET)
public ModelAndView menuResolver(@PathVariable String mainMenu, @PathVariable String subMenu,@PathVariable String secMenu, @ModelAttribute("menu") Menu menu) {
menu.setMainMenu(mainMenu);
menu.setSubMenu(subMenu);
menu.setSecMenu(secMenu);
if (menu.getSubMenu().equals("home")){
String title = "Project - Home Page";
return new ModelAndView("MainPage", "title", title);
}
String title = "Project - Home Page";
return new ModelAndView("MainPage", "title", title);
}
}
解决了：我解决了，在第二类的方法中有多余的参数。
