我有一个愚蠢的问题，我不知道为什么会这样——如果我的映射中有斜线，视图解析会失败；我有这个控制器：

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);
  }
}

完整的堆栈跟踪在这里：http ://pastebin.com/CXwYd9i3这是它的顶部（我在每种情况下都看到我的 system.out）：

[DEBUG] : Could not complete request
java.lang.NullPointerException
at java.net.URLEncoder.encode(URLEncoder.java:205)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:848)
at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:669)
    ...

我真的很想使用第一种方法，它对我正在做的事情更有意义；非常感谢您的帮助！

PS忘记添加，这是我的Java Config：

@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 ("/");
}

尝试这个：

 @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 /
}

我实际上想通了，输入响应让我认为我的 JSP 视图解析器设置有问题，并且确实存在：

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

在 META-INF 之前我没有前导斜线。是的，我在一个奇怪的地方有我的看法。总之感谢！
