如何匹配具有@pathVariable且包含"/"的Spring @RequestMapping? [英] How to match a Spring @RequestMapping having a @pathVariable containing "/"?

问题描述

我正在执行来自客户端的以下请求:

I am doing the following request from the client:

/search/hello%2Fthere/

已对URL编码搜索词"hello/there".

where the search term "hello/there" has been URLencoded.

在服务器上，我尝试使用以下请求映射来匹配此URL:

On the server I am trying to match this URL using the following request mapping:

@RequestMapping("/search/{searchTerm}/") 
public Map searchWithSearchTerm(@PathVariable String searchTerm) {
// more code here 
}

但是我在服务器上收到错误404，因为我没有与URL匹配的内容.我注意到，URL在Spring获取之前就已解码.因此正在尝试匹配/search/hello/那里没有任何匹配项.

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.

我在这里找到了与此问题有关的Jira: http://jira.springframework.org/Browse/SPR-6780 .但是我仍然不知道如何解决我的问题.

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.

有什么想法吗?

谢谢

推荐答案

没有很好的方法(不处理HttpServletResponse).您可以执行以下操作:

There are no good ways to do it (without dealing with HttpServletResponse). You can do something like this:

@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());

    ...
}
