Question

我正在通过邮递员将多部分/表单数据请求（txt文件）发送到骆驼休息端点。检查交换对象时，attachmenstMap显示为空

骆驼语境：

<camelContext id="batch2" xmlns="http://camel.apache.org/schema/spring">
<!-- List of Beans which extend RouteBuilder class-->
<routeBuilder ref="miscRoute"/>
<routeBuilder ref="batchRoute"/>

<!-- REST Configuration -->
<!-- Make sure your contextPath here matches web.xml -->
<restConfiguration component="servlet" bindingMode="json" contextPath="rest" port="8080" enableCORS="true">
  <dataFormatProperty key="prettyPrint" value="true"/>
</restConfiguration>

</camelContext>

BatchRoute扩展了AbstractRouteBuilder：

@Override
public void configure() {

    super.configure();

    rest("/batch")
    .id("createBatch").tag("createBatch")
    .produces(MediaType.APPLICATION_JSON)
    .consumes(MediaType.MULTIPART_FORM_DATA)
    .description("Create Batch")
    .post()
    .bindingMode(RestBindingMode.off)
    .param()
        .name(ApiParameter.BATCH_FILE.toString())
        .type(RestParamType.formData)
        .description(ApiParameter.BATCH_FILE.getDescription())
        .dataType(ApiParameter.BATCH_FILE.getType())
        .endParam()
    .outType(CreateBatchResponse.class)
    .route().removeHeader(Exchange.HTTP_PATH)
    .streamCaching("false")
    .process(new CreateBatchRequestProcessor())
    .process(exchange -> {
        Map<String, DataHandler> attachmentsMap = exchange.getIn().getAttachments();

    })
    .to(ENDPOINT_REQUEST_BATCH2_CREATE_BATCH)
    .endRest();

AbstractRouteBuilder扩展了RouteBuilder：

@Override
public void configure() {

    restConfiguration()
    .component("servlet")
    .port("8080")
    .contextPath("rest")
    .endpointProperty("attachmentMultipartBinding", "true");

请提出建议，因为我们如何从交换对象中提取附件。谢谢。

供以后参考，如果有人遇到此问题并在下面查找详细信息，则为代码段。

exchange.getIn().getAttachments().forEach((id, dh) -> {
        try {               
            InputStream is = dh.getInputStream();               
        } catch (IOException e) {
            e.printStackTrace();
        }

骆驼交换为多部分请求提供空附件
