Question

我正在尝试编写REST API来上传附件。我已经编写了API。但是，当我尝试从POSTMAN打电话时，它抛出了异常。 REST API：

 @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(
            @FormDataParam("attachment") InputStream uploadedInputStream,
            @FormDataParam("attachment") FormDataContentDisposition fileDetail) {
        JSONObject response = new JSONObject();
        JSONObject jobj = new JSONObject();
        if (uploadedInputStream == null) {
            response = StringUtil.getErrorResponse("eleave", jobj, null);
        } else {
            try {
                response.put(Constants.RES_success, true);
                response = companyService.uploadAttachement(uploadedInputStream, fileDetail);
            } catch (JSONException ex) {
                _logger.log(Level.SEVERE, "CompanyRestService.changePassword", ex.getMessage());
                response = StringUtil.getErrorResponse("e01", jobj, ex.getMessage());
            } catch (Exception ex) {
                _logger.log(Level.SEVERE, "CompanyRestService.changePassword", ex.getMessage());
                response = StringUtil.getErrorResponse("erp25", jobj, ex.getMessage());
            }
        }
        return Response.status(200).entity(response.toString()).build();
    }

我尝试了以下屏幕截图，但抛出异常

Answer 1

从例外情况来看，我可以告诉您正在使用Jersey2.x。但是，您似乎正在使用com.sun.jersey.core.header.FormDataContentDisposition，它属于 old Jersey 1.x。

您想改用org.glassfish.jersey.media.multipart.FormDataContentDisposition。

首先删除jersey-multipart依赖项：

<!-- Multipart support for Jersey 1.x -->
<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-multipart</artifactId>
    <version>${jersey.version}</version>
</dependency>

然后添加jersey-media-multipart依赖项：

<!-- Multipart support for Jersey 2.x -->
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>${jersey.version}</version>
</dependency>

修复导入。并在MultiPartFeature或ResourceConfig子类中注册Application。
