Spring 3 MVC 和 Tiles 2 - 当控制器 @RequestMapping 具有 URI 模板时无法显示静态资源

Question

我正在使用 Tiles 2、Spring 3 MVC、Tomcat ver.7 和 Eclipse（Springsource 工具套件）。我希望有人能帮忙。

css和图片不是由控制器处理方法“displayPropertyPage”返回的平铺视图呈现，其@RequestMapping有一个URI模板（@RequestMapping(value = "/getproperty/{propertyID}"，方法 = RequestMethod.GET))。

我正在使用 mvc:resources 和 mvc:default-servlet-handler 标签，因此默认 servlet 为静态资源请求提供服务。我还检查了这个平铺视图生成的 html 脚本，它确实有 css 条目。

控制器处理程序方法返回的其他视图具有简单的路径，例如 (@RequestMapping(value = "/propertylistings", method = RequestMethod.GET)) 显示所有静态资源，包括 css、图片和jquery就好了。

我注意到浏览器上空白图片的“属性信息”的 URL 为 http://localhost:8080/realtyguide/getproperty/resources/images-homes/ pic1.jpg 应该是什么时候 只是 http://localhost:8080/realtyguide/resources/images-homes/pic1.jpg。该 URL 正在从处理程序的 RequestMapping 注释中获取路径“/getproperty”。

图片位于“images-homes”文件夹下。

我的目录结构是：

• 源
  • 主要
    • 网络应用
      • 资源
        • 图片之家
        • CSS
      • WEB-INF

这是我的控制器。返回的视图是一个 tile 定义。

@Controller
public class PropertyPageController {

    private MasterTableService masterTableService;

    @Autowired
    public PropertyPageController(MasterTableService masterTableService) {
        this.masterTableService = masterTableService;
    }

    @RequestMapping(value = "/getproperty/{propertyID}", method = RequestMethod.GET)
    public String displayPropertyPage(@PathVariable("propertyID") String propertyID, Model model) {

        model.addAttribute("mastertable", masterTableService.findByID(propertyID));

        return "propertyinfo.tiledef";
    }

}

这是我的 Spring 应用程序 servlet 配置：

我已经在谷歌上搜索了几天，但找不到解决方案。

感谢您提供的任何帮助。

Answer 1

这是您在视图中引用资源的方式。如果您在视图中将资源称为：

resources/images-homes/pic1.jpg

它将附加到当前控制器的 URL。如果你使用：

/resources/images-homes/pic1.jpg

然后它将引用 Web 服务器根目录，而不包括您的应用程序上下文，假设它不是以 root 身份运行的。

您需要更改资源链接。我假设您正在使用 JSP 来呈现视图。如果是这种情况，请使用核心 JSTL 库中的 c:url 来提供对资源的正确引用：

之前

<img src="resources/images-homes/pic1.jpg"/>

之后

<img src="<c:url value='/resources/images-homes/pic1.jpg'/>"/>
