@RequestMapping斜槓無法返回視圖

Question

我有一個愚蠢的問題我不知道爲什麼會發生這種情況 - 如果我在我的映射中有斜槓，視圖解析失敗;我有這樣的控制器：

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.PathVariable; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class PartialsController { 

    @RequestMapping ("/views/partials/{view}") // Doesn't work! 
    public String partial (@PathVariable ("view") String view) { 
    System.out.println ("\n\nVIEW=\"" + view + "\"\n\n"); 
    return "partials/" + view; 
    } 

    @RequestMapping ("/partial-{view}-view") // Works!!! 
    public String test (@PathVariable ("view") String view) { 
    return partial (view); 
    } 

    @RequestMapping ("/views/partials/{view}/show.html") // Doesn't work! 
    public String test2 (@PathVariable ("view") String view) { 
    return partial (view); 
    } 
} 

完整堆棧跟蹤是在這裏：http://pastebin.com/CXwYd9i3這裏是它的頂部（我看到我在任何情況下的System.out）：

[DEBUG] : Could not complete request 
java.lang.NullPointerException

    ... 

我真的很喜歡使用第一種方法，它對我所做的事情更有意義;非常感謝您的幫助！

P.S.忘了補充，這是我的Java配置：

@Override 
public void onStartup (ServletContext servletContext) throws ServletException { 
    AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext(); 
    mvcContext.register (MvcConfiguration.class); 
    Dynamic dispatcher = servletContext.addServlet ("dispatcher", new DispatcherServlet (mvcContext)); 
    dispatcher.setLoadOnStartup (1); 
    dispatcher.addMapping ("/"); 
} 

Answer 1

其實我想通了，打字的迴應讓我覺得這事是錯的我設立JSP視圖解析器，確實存在：

@Bean (name = "jspViewResolver") 
public ViewResolver jspViewResolver() { 
    return new InternalResourceViewResolver() { 
    { 
     setPrefix ("/META-INF/resources/mev/views/"); 
     setSuffix (".jsp"); 
     setOrder (2); 
     setExposeContextBeansAsAttributes (true); 
    } 
    }; 
} 

我在META-INF之前沒有引導斜槓。是的，我在一個奇怪的地方有我的看法。不管怎樣，謝謝！

試試這個：

@Override 
public void onStartup (ServletContext servletContext) throws ServletException { 
    AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext(); 
    mvcContext.register (MvcConfiguration.class); 
    Dynamic dispatcher = servletContext.addServlet ("dispatcher", new DispatcherServlet (mvcContext)); 
    dispatcher.setLoadOnStartup (1); 
    dispatcher.addMapping ("/*"); //<- It will dispatch all URLs, not only those which starts with/
}
