spring:客户端发送的请求在语法上不正确()
嗨,我在重定向期间收到了下一个错误:
客户端发送的请求在语法上不正确
浏览器显示的URL是:localhost:8080/Project/menu/main/home/0
在这里,我的类首先进行重定向-“从”重定向,然后进行“重定向”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();
}
}
第二类:
@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);
}
}
:我解决了它,第二类的方法中有多余的参数。
回答:
在这种情况下,将org.springframework.web
登录级别设置为DEBUG
inlog4j configuration
<logger name="org.springframework.web"> <level value="DEBUG" />
...
</logger>
例如,当缺少参数或无法将其转换为所需的类型时,日志中将出现异常详细信息。
