@RequestMapping 处理特殊字符

问题描述

我有一个 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
    }
}

我的请求包含以下几行

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

我收到了一个 400 错误的请求

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

当我从请求中删除字符“°”和“í”时，请求可以顺利通过。我的问题是什么？

谢谢。

解决方法

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 (What is the difference between UTF-8 and ISO-8859-1?)。
