将部分uri捕获到PathVariable的Spring请求映射

Question

我需要一些类似的东西来在这里输入链接描述
，所以我的路径将是:/something/else/和/some/more我想像这样映射它：

@RequestMapping(value="/something/**", method=RequestMethod.GET)
public String handleRequest(String theRestOfPath){ /***/ }

或

@RequestMapping(value="/something/**", method=RequestMethod.GET)
public String handleRequest(String[] theRestOfPathArr){ /***/ }

@RequestMapping(value="/something/{a}/{b}/{c}", method=RequestMethod.GET)
public String handleRequest(String a, String b, String c){ /***/ }

@RequestMapping(value = "/something/**", method = RequestMethod.GET)
@ResponseBody
public TextStory getSomething(HttpServletRequest request) {
    final String URI_PATTERN = "^.*/something(/.+?)(\\.json|\\.xml)?$";
    String uri = request.getRequestURI().replaceAll(URI_PATTERN, "$1");
    return doSomethingWithStuff(uri);
}

如果将HttpServletRequest作为方法的参数，则可以访问正在使用的路径。即：

@RequestMapping(value="/something/**", method=RequestMethod.GET)
public String handleRequest(HttpServletRequest request){
    String pattern = (String) request.getAttribute(
                     HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE);
    String path = new AntPathMatcher()
            .extractPathWithinPattern(pattern, request.getServletPath());

    path = path.replaceAll("%2F", "/");
    path = path.replaceAll("%2f", "/");

    StringTokenizer st = new StringTokenizer(path, "/");
    while (st.hasMoreElements()) {
        String token = st.nextToken();
        // ...
    }
}
