我有一个弹簧应用程序，但我无法解决问题。当我使用 aPathVariable时， myRequestMapping中的值被添加到 URI 中并且DispatchHandler变得混乱。
例如，当我请求/Dashboard/project/1131/
我明白了HTTP Status 404 - /Dashboard/project/1131/WEB-INF/jsp/projectDetail.jsp
project/1131 出于某种原因被添加到路径中
当我请求/Dashboard/projectsSpring 找到我的 .jsp 并呈现它时。/project/{projectId}不起作用 - 我得到了上述行为。
这是我的控制器
@Controller
public class ProjectController {
protected final Log logger = LogFactory.getLog(getClass());
@RequestMapping(value = "projects", method=RequestMethod.GET)
public String projects() {
return "/projects";
}
@RequestMapping(value="/project/{projectId}", method=RequestMethod.GET)
public String project(@PathVariable("projectId") String projectId, ModelMap map) {
map.put("projectId", projectId);
logger.info("Project Id: " + projectId);
return "/projectDetail";
}
}

这必须很简单——但我已经查看了文档并在互联网上搜索了几个小时。从我所看到的看来，我所做的一切都是正确的。
