spring boot @PathVariable传递带反斜杠参数 / 的处理

影者东升

我就废话不多说了，大家还是看完整的代码吧~

@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; 
}

补充：springboot的PathVariable接收参数值带点号问题
问题

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

如果version是1.0.0,则返回1.0，这俨然不是我们所期望的。
解决

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

以上为个人经验，希望能给大家一个参考，也希望大家多多支持CodeAE代码之家。如有错误或未考虑完全的地方，望不吝赐教。原文链接：http://cn.voidcc.com/question/p-hdnhwour-ve.html
