@RequestMapping 处理特殊字符

Question

I have a REST API

@RequestMapping(value = "/Save", method = RequestMethod.POST, 
            consumes = {"application/json;charset=ISO-8859-1" }, 
            produces = {"application/json;charset=ISO-8859-1" })    
public SaveResponse save(@RequestBody SaveRequest request) {
        //some codes
    }
}

My request contains the following lines

{
  :
  :
      "mailingAddress": {
      "addressLine1": "Carrera 36E N°",
      "addressLine2": "Medellín, Antioquia",
      "country": "COL"
    }
  :

And I received a 400 Bad Request

HTTP/1.1 400 Bad Request
Cache-Control: no-cache, no-store, max-age=0, must-revalidate

And when I removed the characters "°" and "í" from the request, then the request can go through with no error. What is my problem?

Thank you.

您可以尝试将字符集从 ISO-8859-1 更改为 UTF-8，因为前者不支持如此宽的字符映射数组（ UTF-8 和 ISO-8859-1 之间有什么区别？ ）。
