Spring 如何从HttpHeader中提取客户端数据？

我有一个登录post请求

@RequestMapping(value = EWPRestContants.DO_LOGIN, method = RequestMethod.POST, consumes=MediaType.APPLICATION_XML_VALUE,produces=MediaType.TEXT_PLAIN_VALUE)
public ResponseEntity<String> doLogin(@RequestBody Loginrequest logReq,@RequestHeader HttpHeaders headers, HttpServletRequest request, HttpServletResponse httpResponse) throws Exception {
   //........
     }

@RequestMapping（value=EWPRestContants.DO\u LOGIN，method=RequestMethod.POST，consumes=MediaType.APPLICATION\u XML\u value，products=MediaType.TEXT\u PLAIN\u value）
公共响应属性doLogin（@RequestBody Loginrequest logReq、@RequestHeader HttpHeaders、HttpServletRequest、HttpServletResponse httpResponse）引发异常{
//........
}

我想从标题中提取数据。是否有这样做的API

假设我的标题包含客户msIsdn编号和名称。如何获取这些详细信息。getFirst（）用于获取用户代理详细信息或仅获取起始行

这就是答案。

stringid=headers.getFirst（“id”）
类似

@RequestHeader（value=“User Agent”，defaultValue=“foo”）字符串userAgent

@RequestMapping(value = EWPRestContants.DO_LOGIN, method = RequestMethod.POST, consumes=MediaType.APPLICATION_XML_VALUE,produces=MediaType.TEXT_PLAIN_VALUE)
public ResponseEntity<String> doLogin(@RequestBody Loginrequest logReq,@RequestHeader(value="User-Agent", defaultValue="foo") String userAgent,@RequestHeader(value="Accept-Language") String acceptLanguage, HttpServletRequest request, HttpServletResponse httpResponse) throws Exception {
   //........
     }

@RequestMapping（value=EWPRestContants.DO\u LOGIN，method=RequestMethod.POST，consumes=MediaType.APPLICATION\u XML\u value，products=MediaType.TEXT\u PLAIN\u value）
public ResponseEntity doLogin（@RequestBody Loginrequest logReq、@RequestHeader（value=“User Agent”、defaultValue=“foo”）String userAgent、@RequestHeader（value=“Accept Language”）String acceptLanguage、HttpServletRequest、HttpServletResponse）引发异常{
//........
}

或来自

    @RequestMapping(value = EWPRestContants.DO_LOGIN, method = RequestMethod.POST, consumes=MediaType.APPLICATION_XML_VALUE,produces=MediaType.TEXT_PLAIN_VALUE)
    public ResponseEntity<String> doLogin(@RequestBody Loginrequest logReq,@RequestHeader HttpHeaders headers, HttpServletRequest request, HttpServletResponse httpResponse) throws Exception {
String userAgent = headers.getFirst(HttpHeaders.USER_AGENT);
         }

@RequestMapping（value=EWPRestContants.DO\u LOGIN，method=RequestMethod.POST，consumes=MediaType.APPLICATION\u XML\u value，products=MediaType.TEXT\u PLAIN\u value）
公共响应属性doLogin（@RequestBody Loginrequest logReq、@RequestHeader HttpHeaders、HttpServletRequest、HttpServletResponse httpResponse）引发异常{
字符串userAgent=headers.getFirst（HttpHeaders.USER\u AGENT）；
}
从第二个解决方案中，
用户代理无法解析或不是字段
我得到以下错误。感谢@kuhajeyan的努力。
