如何将Spring MVC控制器映射到带有和不带有尾随斜线的uri？

Question

我有一个Spring控制器，其中有几个用于不同URI的RequestMapping。我的servlet是“UI”。servlet的基本URI只使用尾随斜杠。我希望我的用户不必输入尾随斜杠。

此URI的工作方式是：

http://localhost/myapp/ui/

http://localhost/myapp/ui

<servlet>
    <servlet-name>ui</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>ui</servlet-name>
    <url-pattern>/ui/*</url-pattern>
</servlet-mapping>    

@Controller
public class UiRootController {

    @RequestMapping(value={"","/"})
    public ModelAndView mainPage() { 
        DataModel model = initModel();
        model.setView("intro");     
        return new ModelAndView("main", "model", model);
    }

    @RequestMapping(value={"/other"})
    public ModelAndView otherPage() { 
        DataModel model = initModel();
        model.setView("otherPage");     
        return new ModelAndView("other", "model", model);
    }

}

使用Springboot，我的应用程序可以通过将@RequestMapping的“value”选项设置为空字符串来回复带有和不带有尾随斜杠的内容：

@RestController
@RequestMapping("/some")
public class SomeController {
//                  value = "/" (default) ,
//                  would limit valid url to that with trailing slash.
    @RequestMapping(value = "", method = RequestMethod.GET)
    public Collection<Student> getAllStudents() {
        String msg = "getting all Students";
        out.println(msg);
        return StudentService.getAllStudents();
    }
}
