java - Spring MVC 中的 UTF-8 编码问题

Question

我有一个 Spring MVC bean，我想通过设置编码 UTF-8 来返回土耳其字符。但是虽然我的字符串是“şŞğĞİıçÇöÖüÜ”，但它返回为“??????çÇöÖüÜ”。而且当我查看响应页面(即 Internet Explorer 页面)时，编码是西欧 iso，而不是 UTF-8。

代码如下:

    @RequestMapping(method=RequestMethod.GET,value="/GetMyList")
public @ResponseBody String getMyList(HttpServletRequest request, HttpServletResponse response) throws CryptoException{
    String contentType= "text/html;charset=UTF-8";
    response.setContentType(contentType);
    try {
        request.setCharacterEncoding("utf-8");
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    response.setCharacterEncoding("utf-8");     
    String str="şŞğĞİıçÇöÖüÜ";
    return str;
}   

Answer 1

我想通了，你可以添加到请求映射中产生 = "text/plain;charset=UTF-8"

@RequestMapping(value = "/rest/create/document", produces = "text/plain;charset=UTF-8")
@ResponseBody
public void create(Document document, HttpServletRespone respone) throws UnsupportedEncodingException {

    Document newDocument = DocumentService.create(Document);

    return jsonSerializer.serialize(newDocument);
}
