java Spring找不到HTTPrequest的映射
我正在尝试创建一个简单的web应用程序,它允许用户创建主题并对其进行评论。这个想法是,在开始一个主题后,用户被重定向到这个主题的页面
@Controller
public class HomeController {
@RequestMapping(value = "/create", method = RequestMethod.GET)
public ModelAndView create(Locale locale, Model model)
{
Topic newTopic = new Topic();
logger.info("HomeControlller: Create");
List<Tag> tagList = newTopic.getTagLict();
Hashtable modelData = new Hashtable();
modelData.put("newTopic", newTopic);
modelData.put("tagList", tagList);
return new ModelAndView("create", modelData);
}
@RequestMapping(value = "/create", method = RequestMethod.POST)
public String saveNewTopic(@ModelAttribute("newTopic")Topic topic, BindingResult result, Model model)
{
validate(topic, result);
// Go to the "Show topic@ page
return "redirect:details/"+service.saveTopic(topic);
}
@RequestMapping(value = "/details/(topicId)", method = RequestMethod.GET)
public ModelAndView details(@PathVariable(value="topicId") int id)
{
logger.info("HomeControlller: Details: Found a method");
Topic topicById = service.findTopicByID((long) id);
logger.info("HomeControlller: Details: Performing redirect");
return new ModelAndView("/topic/", "model", topicById);
}
}
但是在创建主题后,我收到一个错误在名为“appServlet”的DispatcherServlet中找不到URI为[/simpleblog/details/9]的HTTP请求的映射。我不明白哪里不对,因为HTTP请求是用注释映射的。它可以使用create()和saventopic()函数,但不能使用details()函数

path变量的语法是
{foo}
,而不是(foo)
