java - @PathVariable in SpringBoot with slashes in URL

Question

I have to get params from URL using @PathValiable in SpringBoot application. These params often have slashes. I don't have a control about what a user would enter in URL so I would like to get what he has entered and then I can handle with it.

I have already looked through materials and answers here, I don't think that for me the good solution is to ask users somehow encode the entering params.

The SpringBoot code is simple:

@RequestMapping("/modules/{moduleName}")
@ResponseBody
public String moduleStrings (@PathVariable("moduleName") String moduleName) throws Exception {

  ...

}

So the URL for example would be the following:

http://localhost:3000/modules/...

The issue is that the param moduleName often has slashes. For example,

metadata-apicb-metadata-services OR
app-customization-service-impl\modules\expand-link-schemes\common\app-customization-service-api

So a user definetely can enter:

http://localhost:3000/modules/metadata-apicb-metadata-services

Is this possible to get everything what a user has entered in URL after /modules/?

If anyone tell me what are the good ways to handle such issue.

Answer 1

Basing on P.J.Meisch's answer I have come to the simple solution for my case. Also it allows to take into account several slashes in the URL param. It doesn't allow to work with backslashes as in the previous answer too.

@RequestMapping(value = "/modules/**", method = RequestMethod.GET)
@ResponseBody
public String moduleStrings(HttpServletRequest request) {

    String requestURL = request.getRequestURL().toString();

    String moduleName = requestURL.split("/modules/")[1];

    return "module name is: " + moduleName;

}
