使用Spring映射到web.xml中的根，找不到静态资源

Question

我正在尝试将请求映射到servlet根（正确的术语？）。我正在将URL映射到正确的视图，但是找不到页面的一部分的所有静态内容-CSS，JavaScript，图像。

所以在我的web.xml中，我的servlet标记看起来像这样

<servlet-mapping>
    <servlet-name>springapp</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

我的控制器看起来像这样：

@RequestMapping("/shop")
public class TheShopController extends MyBaseController {

    public static String VIEW = "Tile.Shop";

    @Override
    @RequestMapping(method = RequestMethod.GET)
    protected ModelAndView processRequest(HttpServletRequest req, HttpServletResponse resp) {
        ModelAndView mav = new ModelAndView(VIEW);
        return mav;
    }

}

MyBaseController非常简单。看起来像这样：

public abstract class MyBaseController extends AbstractController {

    protected Logger log = Logger.getLogger(getClass());

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest req, HttpServletResponse resp) 
        throws Exception {

        ModelAndView mav = processRequest(req, resp);
        return mav;
    }

    protected abstract ModelAndView processRequest(HttpServletRequest req, HttpServletResponse resp);
}

我在视图层中使用了Tiles。我的配置如下：

/WEB-INF/tiles-defs.xml

正如我提到的，可以找到视图，但是找不到作为页面端口的静态资源。这是一些典型的注销日志：

What I’m trying to do is map requests to the servlet root (correct terminology?). I’m at the point where URLs are mapped to correct view but all the static content - css, javascript, images - that is part of the page cannot be found.

So in my web.xml my servlet tag looks like this

springapp
/

My controller looks something like this:

@RequestMapping(“/shop”)
public class TheShopController extends MyBaseController {

public static String VIEW = "Tile.Shop";

@Override
@RequestMapping(method = RequestMethod.GET)
protected ModelAndView processRequest(HttpServletRequest req, HttpServletResponse resp) {
    ModelAndView mav = new ModelAndView(VIEW);
    return mav;
}

}
MyBaseController is very simple. It looks like this:

public abstract class MyBaseController extends AbstractController {

protected Logger log = Logger.getLogger(getClass());

@Override
protected ModelAndView handleRequestInternal(HttpServletRequest req, HttpServletResponse resp) 
    throws Exception {

    ModelAndView mav = processRequest(req, resp);
    return mav;
}

protected abstract ModelAndView processRequest(HttpServletRequest req, HttpServletResponse resp);

}
I’m using Tiles in my view layer. My configuration is as follows:

/WEB-INF/tiles-defs.xml

As I mentioned, the views are found but the static resources that are a port of the page can’t be found. Here is some typical logging out put:

2010-01-24 17:25:01,777 DEBUG [http-8080-7] servlet.DispatcherServlet (DispatcherServlet.java:690) - DispatcherServlet with name ‘springapp’ processing GET request for [/springapp/static/css/account.css] 2010-01-24 17:25:01,778 WARN [http-8080-4] servlet.DispatcherServlet (DispatcherServlet.java:962) - No mapping found for HTTP request with URI [/springapp/static/css/shop.css] in DispatcherServlet with name ‘springapp’ 2010-01-24 17:25:01,778 DEBUG [http-8080-6] servlet.FrameworkServlet (FrameworkServlet.java:677) - Successfully completed request 2010-01-24 17:25:01,778 WARN [http-8080-5] servlet.DispatcherServlet (DispatcherServlet.java:962) - No mapping found for HTTP request with URI [/springapp/static/css/offers.css] in DispatcherServlet with name ‘springapp’ 2010-01-24 17:25:01,778 WARN [http-8080-3] servlet.DispatcherServlet (DispatcherServlet.java:962) - No mapping found for HTTP request with URI [/springapp/static/css/scrollable-buttons.css] in DispatcherServlet with name ‘springapp’

Going to http://localhost:8080/springapp/shop works fine but the css and images are missing.

I think that using Tiles is somehow complicating things but I”m reluctant to get rid of it. I’m wondering if I need to adjust my view resolution configuration needs to be tweeked somehow? Chaining view resolvers maybe? I’m just not that experienced in doing that.

The problem is that requests for the static content go to the dispatcherServlet, because it’s mapped as / . It’s a very common problem in applications with “RESTful” URLs (that is, without any prefix in the DispatcherServlet mapping).

There are several possible ways to solve this problem:

Since Spring 3.x the preferred way to access static resources is to use : web.xml:

springapp
/

Spring config:

See also MVC Simplifications in Spring 3

1. Use URL rewrite filter
   See mvc-basic example here

2. Set a prefix for the default servlet:

default
/static/*

That is, request for /static/images/image.png will return the file named /images/image.png However, this way is incompatible across different servlet containers (doesn’t work in Jetty), see workarounds here

1. Set static content extensions for the default servlet:

default
.png
