当我尝试通过 JAX-RS REST API 上传 csv 格式的 excel 文件时，我从浏览器收到 415（不支持的媒体类型）。Web 应用程序在嵌入式 Tomcat 服务器下部署和运行。

如果我在不是嵌入式 tomcat 的 tomcat 7 服务器中部署我的 web 应用程序，我可以成功上传 csv 文件。

感谢您为解决我的问题提供的意见。

JAX-RS API

/**
     * API will import the ConfigSet from CSV file request and returns the response in Text/Html format.
     * @param is
     * @param request
     * @param response
     */


@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.TEXT_HTML)
public void upload(@FormDataParam("uploadedFile") InputStream is, @Context HttpServletRequest request, @Context HttpServletResponse response) {
    // read it with BufferedReader

    ObjectMapper mapper = new ObjectMapper();
    PrintWriter out;
    BufferedReader br = null;
    try {
        br = new BufferedReader(new InputStreamReader(is));
        ConfigSetResponse configSetResponse = new CSVReader().csvReader(br);
        out = response.getWriter();
        mapper.writeValue(out, configSetResponse);

    } catch (Exception e) {
        logger.error("Error while uploading :", e);
        e.printStackTrace();
    } finally {
        // Close the file once all data has been read.
        try {
            if (null != br) {
                br.close();
            }
            if (null != is) {
                is.close();
            }
        } catch (IOException e) {
            logger.error("Error while uploading :", e);
            e.printStackTrace();
        }
    }
}

调用此 JAX-RS API 的 Java 脚本代码：

var importForm = $( modal ).find("#icwExportForm");                 


                        importForm.ajaxForm({
                            contentType: false,
                            success : function(responseObj) {
                                try{



                                    refreshConfigSetUI(eval(responseObj));
                                    ccw.modal.hide(modal);
                                }catch(e){
                                    ccw.modal.hide(modal);
                                    $('#runtimeErrorMessages').html(commonErrorData);                                   
                                }
                            },
                            error : function(request, msg,  err) {
                                ccw.modal.hide(modal);
                                $('#runtimeErrorMessages').html(commonErrorData);
                            }
                        });

                        importForm.attr("action", "config/configutil/upload");
                        importForm.attr("Content-Type" ,"multipart/form-data");
                        importForm.submit();
                    });

HTML页面：

<form class="icwExportForm" id="icwExportForm"   method="post" action="" name="ExportOptionInputForm" enctype="multipart/form-data" accept-charset="utf-8">

<div class="icwImportContent" style="padding: 5px 0px 10px 20px">
                    <input type="file" name="uploadedFile" value="" id="icwUploadFile" class="icwButton" size="45"  tabindex="1" />

</div>

</form>
