java - spring mvc中资源的动态路径

Question

在 Java-Jersey 中，可以接收资源的动态路径，例如

localhost:8080/webservice/this/is/my/dynamic/path

@GET
@Path("{dynamicpath : .+}")
@Produces(MediaType.APPLICATION_JSON)     
public String get(@PathParam("dynamicpath") String p_dynamicpath) {
     return p_dynamicpath;
} 

打印出:this/is/my/dynamic/path

问题:如何在 Spring MVC 中执行此操作？

Answer 1

对于路径中的多个项目，您可以像这样访问动态路径值:

@RequestMapping(value="/**", method = RequestMethod.GET)
public String get(HttpServletRequest request) throws Exception {
    String dynPath = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    System.out.println("Dynamic Path: " + dynPath );
    return dynPath;
}

如果你事先知道你会拥有许多级别的路径变量，你可以像这样显式地编码它们

@RequestMapping(value="/{path1}/{path2}/**", method = RequestMethod.GET)
public String get(@PathVariable("path1") String path1,
          @PathVariable("path2") String path2,
          HttpServletRequest request) throws Exception {
    String dynPath = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    System.out.println("Dynamic Path: " + dynPath );
    return dynPath;
}

如果你想在你的浏览器中看到返回的字符串，你还需要声明方法@ResponseBody(这样你返回的字符串就是你响应的内容):

@RequestMapping(value="/**", method = RequestMethod.GET, produces = "text/plain")
@ResponseBody
public String get(HttpServletRequest request) throws Exception {
