我想要上传的文件将始终是一个xml文件.我想将content-type设置为application / xml
这是我的代码：
这是我的代码：
MultiValueMap<String,Object parts = new LinkedMultiValueMap<String,Object(); parts.add("subject","some info");
ByteArrayResource xmlFile = new ByteArrayResource(stringWithXMLcontent.getBytes("UTF-8")){
@Override
public String getFilename(){
return documentName;
}
};
parts.add("attachment",xmlFile);
//sending the request using RestTemplate template;,the request is successfull
String result = template.postForObject(getRestURI(),httpEntity,String.class);
//but the content-type of file is 'application/octet-stream'
原始请求如下所示：
Content-Type:
multipart/form-data;boundary=gbTw7ZJbcdbHIeCRqdX81DVTFfA-oteHHEqgmlz
User-Agent: Java/1.7.0_67 Host: some.host Connection: keep-alive
Content-Length: 202866
--gbTw7ZJbcdbHIeCRqdX81DVTFfA-oteHHEqgmlz Content-Disposition: form-data; name="subject" Content-Type: text/plain;charset=ISO-8859-1
Content-Length: 19
some info
--gbTw7ZJbcdbHIeCRqdX81DVTFfA-oteHHEqgmlz Content-Disposition: form-data; name="attachment"; filename="filename.xml" Content-Type:
application/octet-stream Content-Length: 201402
....xml file contents here ..
该文件的内容类型正在生成为“应用程序/八位字节流”,其中我希望它是“application / xml”
我如何设置文件的内容类型？
解决方法
从此链接中提取出来后,我找出了解决方案：
Making a multipart post request with compressed jpeg byte array with spring for android
解决方案是将ByteArrayResource放在具有所需标头的HttpEntity中,并将HttpEntity添加到Multivaluemap(而不是添加ByteArrayResource本身).
码：
Resource xmlFile = new ByteArrayResource(stringWithXMLcontent.getBytes("UTF-8")){
@Override
public String getFilename(){
return documentName;
}
};
HttpHeaders xmlHeaders = new HttpHeaders();
xmlHeaders.setContentType(MediaType.APPLICATION_XML);
HttpEntity<Resource> xmlEntity = new HttpEntity<Resource>(xmlFile,xmlHeaders);
parts.add("attachment",xmlEntity);
