How to match a Spring @RequestMapping having a @pathVariable containing "/"?
提问by yeforriak
I am doing the following request from the client:
我正在执行来自客户的以下请求：
/search/hello%2Fthere/
/search/hello%2Fthere/
where the search term "hello/there" has been URLencoded.
其中搜索词“hello/there”已被 URL 编码。
On the server I am trying to match this URL using the following request mapping:
在服务器上，我尝试使用以下请求映射匹配此 URL：
@RequestMapping("/search/{searchTerm}/")
public Map searchWithSearchTerm(@PathVariable String searchTerm) {
// more code here
}
But I am getting error 404 on the server, due I don't have any match for the URL. I noticed that the URL is decoded before Spring gets it. Therefore is trying to match /search/hello/there which does not have any match.
但是我在服务器上收到错误 404，因为我没有任何匹配的 URL。我注意到 URL 在 Spring 得到它之前就被解码了。因此试图匹配没有任何匹配的 /search/hello/there。
I found a Jira related to this problem here: http://jira.springframework.org/browse/SPR-6780.But I still don't know how to solve my problem.
我在这里找到了与此问题相关的 Jira：http: //jira.springframework.org/browse/SPR-6780。但我仍然不知道如何解决我的问题。
Any ideas?

There are no good ways to do it (without dealing with HttpServletResponse). You can do something like this:
没有好的方法可以做到（不处理HttpServletResponse）。你可以这样做：
@RequestMapping("/search/**")
public Map searchWithSearchTerm(HttpServletRequest request) {
// Don't repeat a pattern
String pattern = (String)
request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE);
String searchTerm = new AntPathMatcher().extractPathWithinPattern(pattern,
request.getServletPath());
...
}
