Question

我有一个这样的REST API：

  @RequestMapping(value = "/services/produce/{_id}", method = RequestMethod.PATCH, 
  consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
  public String patchObject(@RequestBody PatchObjectRequest obj, 
      @PathVariable("_id") String id) {
  // some code
  }

我的问题是可能提供的ID格式为：

US%2FCA%2FSF%2FPlastic

这是＆＃34; US / CA / SF / Plastic＆＃34;。

的网址编码

我的问题是，当一个％字符放入URL时，@ RequestMapping不会将它映射到此方法，它将返回404.有没有办法接受其中包含％字符的id作为URL？

Answer 1

You are receiving this error because using it as path variable it is decoded and then server tries to match it to a path that doesn't exits. Similar questions where posted a few years ago: How to match a Spring @RequestMapping having a @pathVariable containing "/"?, urlencoded Forward slash is breaking URL. A good option for you would be to change _id from @PathVariable to @RequestParam and problem solved, and remove it from path.

Answer 2

希望你可以在路径变量中添加正则表达式，如：

@RequestMapping(value = "/services/produce/{_id:.+}", 
  method = RequestMethod.PATCH, 
  consumes = MediaType.APPLICATION_JSON_VALUE, 
  produces = MediaType.APPLICATION_JSON_VALUE)

Spring @RequestMapping处理特殊字符
