标题可能看起来很普通,但是没有一个适合我的问题.

我有一个REST服务,它接受多部分形式的常规参数和文件.

我想使用resttemplate将数据和文件发送到上述rest服务.

直到我发送正常的字符串数据为止,没有任何问题.一旦我添加了发送字节的代码,那么我开始收到400错误的请求错误.

如果我注释了发送ByteArrayResource的代码,那么它将开始为正常参数工作.

下面是示例代码

休息服务控制器

@RestController

@RequestMapping(value="/ticket")

public class UserTicketController {

@RequestMapping(value="/createTicket.do",method={RequestMethod.POST},

consumes = {MediaType.MULTIPART_FORM_DATA_VALUE},headers={"content-type="+MediaType.MULTIPART_FORM_DATA_VALUE})

public void createTicket(@ModelAttribute ServiceDeskRequest serviceDeskRequest, HttpServletRequest request,HttpServletResponse response) throws Exception{

}

}

Servicedeskrequest模型属性为

public class ServiceDeskRequest implements Serializable{

private String jsonData;

private MultipartFile attachment;

}

应用程序的context.xml

客户端代码

RestTemplate restTemplate = new RestTemplate();

MultiValueMap requestParamerterMap = new LinkedMultiValueMap();

requestParamerterMap.add("jsonData", jsonData);

MultipartFile attachment = userRequest.getAttachment();

if(attachment!=null && attachment.getOriginalFilename()!=null) {

ByteArrayResource byteArrayResource = new ByteArrayResource(attachment.getBytes(), attachment.getOriginalFilename());

requestParamerterMap.add("attachment", byteArrayResource);

}

HttpHeaders headers = new HttpHeaders();

headers.setContentType(MediaType.MULTIPART_FORM_DATA);

HttpEntity> requestEntity = new HttpEntity>(requestParamerterMap, headers);

String response = restTemplate.postForObject(targetUrl, requestEntity, String.class);
