我想使用多部分表单数据上传文件，但 URLDecoder 有问题。服务代码如下：

@POST
@Path("/document")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response storeTravelDocument(
        @Context UriInfo uriInfo,
        @FormParam(value = "IDNR") String idnr,
        @FormParam(value="DOCNR") String documentNr,
        @FormParam(value="ISSUE_DATE") String issueDate,
        @Multipart(value = "image", type="image/jpeg") InputStream pictureStream)
{..

我与三个客户进行了测试，例如放心：

given().
        formParam("IDNR", "A000000A").
        formParam("DOCNR", "00001").
        formParam("ISSUE_DATE", "14.06.2010").
        multiPart("image", new File(picturePath), "image/jpeg").
expect().
        statusCode(Response.Status.CREATED.getStatusCode()).
when().
        post("/document");

或 HttpClient：

    // build mulitpart entity
    MultipartEntity entity = new MultipartEntity();

    entity.addPart("IDNR", new StringBody("A000000A"));
    entity.addPart("DOCID", new StringBody("00001"));
    entity.addPart("ISSUE_DATE", new StringBody("14.06.2010"));

    FileBody fileBody = new FileBody(new File(picturePath), "image/jpeg");
    entity.addPart("image", fileBody);

    // build post request
    String uri = System.getProperty("service.url") + "/document"; 
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(uri);
    httpPost.setEntity(entity);

    // execute request
    HttpResponse response = httpClient.execute(httpPost);
    int code = response.getStatusLine().getStatusCode();

    // validate
    assert code == Response.Status.CREATED.getStatusCode();

在所有情况下，我都会收到以下异常：

我了解 CXF 尝试解码我​​的文件（图片）并由于无效字符而引发异常，但我想阻止这种解码。该文件应仅作为 UTF-8 流传输，未更改且未解码。谁能帮我？

Sergey Beryozkin在 Apache CXF邮件列表中解决了这个问题。

总结一下：

此声明发生的情况是表单有效负载处理器假定最后一个参数只是一个更普通的 multipart/form-data 参数。当您有一个“混合的”多部分/表单数据有效负载，包含简单的字符串名称/值对以及二进制部分时，最好避免使用@FormParam 或@Multipart 注释，只使用 MultipartBody 输入参数 - 它会提供对所有单个部分的类型安全访问。

用@Multipart 替换@FormParam 应该可以解决问题（作为引入MultipartBody 的替代方法），但是@FormParam 和@Multipart 的混合也应该可以理想地工作。将检查此问题。

我选择用@Multipart 替换@FormParam，这很有效。
