spring boot @ PathVariable processing of passing and with backslash parameter

I won't talk too much, let's look at the complete code ~

@RequestMapping(value = "/modules/{moduleBaseName}/**", method = RequestMethod.GET) 
@ResponseBody 
public String moduleStrings(@PathVariable String moduleBaseName, HttpServletRequest request) { 
  final String path = 
   request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE).toString(); 
  final String bestMatchingPattern = 
   request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE).toString(); 
  String arguments = new AntPathMatcher().extractPathWithinPattern(bestMatchingPattern, path); 
  String moduleName; 
  if (null != arguments && !arguments.isEmpty()) { 
   moduleName = moduleBaseName + '/' + arguments; 
  } else { 
   moduleName = moduleBaseName; 
  } 
  return "module name is: " + moduleName; 
} 

Supplement: The problem of PathVariable receiving parameter value with dot number in springboot

Problem

 @RequestMapping(value = "/{version}",method = RequestMethod.GET)
  public String demo(@PathVariable String version){
    return version;
  }

If version is 1.0. 0, it returns 1.0, which is not what we expect.

Solve

@RequestMapping(value = "/{version:.+}",method = RequestMethod.GET)
  public String demo(@PathVariable String version){
    return version;
  }
