我正在尝试创建一个简单的网络应用程序，它允许用户创建主题并对其进行评论。这个想法是，启动一个主题后，用户被重定向到该主题的页面。
@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，我收到错误在名称为“appServlet”的 DispatcherServlet 中未找到带有 URI [/simpleblog/details/9] 的 HTTP 请求的映射。我不明白出了什么问题，因为 HTTP 请求是用注释映射的。它适用于 create() 和 saveNewTopic() 函数，但不适用于 details() 函数。
最佳答案
路径变量的语法是{foo}，而不是(foo):
@RequestMapping(value = "/details/{topicId}", method = RequestMethod.GET)
public ModelAndView details(@PathVariable(value="topicId") int id)
关于java - Spring找不到HTTP请求的映射，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9645215/
