任何线索都会有帮助。

好吧，代码中有几点可以改进

首先，由于您使用的是MultipartEntityBuilder，这意味着您使用的是Apache的HttpClient版本4.3+，因此为了获得最佳兼容性，您应该使用它

第三，在这样一个小的例子中，您实际上不需要使用转换器，您可以这样做：

public class LoggingMain {

    private static final Logger logger = Logger.getLogger(LoggingMain.class);

    public static void main(String[] args) throws Exception {
        CamelContext camelContext = new DefaultCamelContext();
        try {
            camelContext.addRoutes(new RouteBuilder() {
                @Override
                public void configure() throws Exception {
                    from("file:C:\\temp?delay=5000&move=processed&moveFailed=error&antExclude=**/processed/**,**/error/**")
                            .process(new Processor() {
                                public void process(Exchange exchange) throws Exception {
                                    StringBody username = new StringBody("username", ContentType.MULTIPART_FORM_DATA);
                                    StringBody password = new StringBody("password", ContentType.MULTIPART_FORM_DATA);

                                    MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
                                    multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
                                    multipartEntityBuilder.addPart("username", username);
                                    multipartEntityBuilder.addPart("password", password);

                                    String filename = (String) exchange.getIn().getHeader(Exchange.FILE_NAME);
                                    File file = exchange.getIn().getBody(File.class);
                                    multipartEntityBuilder.addPart("upload", new FileBody(file, ContentType.MULTIPART_FORM_DATA, filename));

                                    exchange.getIn().setBody(multipartEntityBuilder.build());
                                }
                            })
                            .to("http4://localhost:8080/JAX_RS_Application/resource/restwb/upload");
                }
            });

            camelContext.getRestConfiguration();
            camelContext.start();
            Thread.sleep(5000);
            camelContext.stop();

        } catch (Exception e) {
            logger.error(e.getMessage());
        }
    }

}
我希望这有帮助

谢谢你的回复！！！我已经尝试过将内容类型设置为multipart/form data，这会给我带来400个错误…其次，将body设置为HttpEntity会给我带来一个错误，它说。。找不到用于将MultipartFormEntity转换为InputStream的转换器，因此我必须创建一个转换器。。。。是的，我同意你的观点，httpclient builder是http4最受支持的，我会尝试一下……我提供的示例对我来说很好，你可以自己尝试：而且必须将内容类型设置为多部分/表单数据，因为你的服务只使用该类型，任何其他类型都会导致错误。虽然由于您使用的是多部分实体，我想可以忽略它。在使用Camel之前，您实际上已经尝试过使用一些rest工具或SOAPUI或类似工具发送它，以验证一切是否正常？是的。。我用邮递员测试了这项服务，效果很好。
