如何为特定的@RequestMapping 启用贪婪的@PathVariable？ [复制]

Question

我尝试通过休息服务启用目录浏览。它的定义是这样的：

@RequestMapping(path="ls/{path:.+}", method = RequestMethod.GET)
public List<String> getDirectoryListing(@PathVariable("path") String path) throws IOException {
  // ...
}

但是，如果我使用类似目录的定义，PathVariable {path:.+} 会带来问题。例如，

$ curl http://localhost:8080/fileRepo/ls/dir/subdir
                                         \___ ___/
                                             V 
                                          {path:.+} 

会导致

{
 "timestamp":1485690489272,
 "status":404,"error":"Not Found",
 "message":"No message available",
 "path":"/dataset/ls/processed/dir1/subdir"
 }

并在控制台上显示调试消息

s.w.s.m.m.a.RequestMappingHandlerMapping : Looking up handler method for path /files/ls/dir1/subdir
s.w.s.m.m.a.RequestMappingHandlerMapping : Did not find handler method for [/files/ls/dir1/subdir]
o.s.w.s.handler.SimpleUrlHandlerMapping  : Matching patterns for request [/files/ls/dir1/subdir] are [/**]
o.s.w.s.handler.SimpleUrlHandlerMapping  : URI Template variables for request [/files/ls/dir1/subdir] are {}

所以。如何告诉 RequestMappingHandlerMapping ls/{path:.+} 应该全部解析为 getDirectoryListing？

如果您在路径变量中发送 dir/subdir，则需要转义路径变量中的“/”字符。 您需要在请求处理程序级别encode url 的路径变量部分和decode。
