File upload Jersey ApacheConnector多部分文件上载-未找到多部分边界

我希望有人能帮忙

我已经为我的SpringWebMVC应用程序编写了一个客户端，我使用的是jersey和ApacheConnector。我需要保留jsessionid，不知道如何使用jersey的HttpUrlConnector实现这一点。我还应该提到，在我需要跟踪会话之前，文件上传服务与jersey的HttpUrlConnector一起工作

我知道SpringWebMVC文件上传服务可以工作，因为我的web前端可以上传文件。为了完整起见，它看起来是这样的

@ResponseBody
private Image onSubmit(@ModelAttribute("uploadedFile") ImageUpload imageUpload) {   
        service.create(imageUpload);
        return new Image();
}

客户端初始化代码如下所示：

clientConfig = new ClientConfig();
connector = new ApacheConnector(clientConfig);
clientConfig.connector(connector);
client = ClientBuilder.newBuilder().withConfig(clientConfig)
                .register(MultiPartFeature.class)
                .register(JacksonJsonProvider.class).build();
target = client.target(url);

File file = new File(fileName);
FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
FormDataBodyPart bodyPart = new FormDataBodyPart("file", file,
                MediaType.APPLICATION_OCTET_STREAM_TYPE);
formDataMultiPart.bodyPart(bodyPart);
response = target
                .path(path)
                .request()
                .post(Entity.entity(formDataMultiPart,
                        formDataMultiPart.getMediaType()), Response.class);

我已经注册了MultiPartFeature和JacksonJsonProvider，因为我想使用jackson2.x

上载文件的客户端代码如下所示：

clientConfig = new ClientConfig();
connector = new ApacheConnector(clientConfig);
clientConfig.connector(connector);
client = ClientBuilder.newBuilder().withConfig(clientConfig)
                .register(MultiPartFeature.class)
                .register(JacksonJsonProvider.class).build();
target = client.target(url);

File file = new File(fileName);
FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
FormDataBodyPart bodyPart = new FormDataBodyPart("file", file,
                MediaType.APPLICATION_OCTET_STREAM_TYPE);
formDataMultiPart.bodyPart(bodyPart);
response = target
                .path(path)
                .request()
                .post(Entity.entity(formDataMultiPart,
                        formDataMultiPart.getMediaType()), Response.class);

我还尝试了如下代码：

final FileDataBodyPart filePart = new FileDataBodyPart("file", new File(fileName));
         final MultiPart multipart = new FormDataMultiPart()
            .field("foo", "bar")
            .bodyPart(filePart);
response = target
                .path(path)
                .request()
                .post(Entity.entity(multipart,
                        multipart.getMediaType()), Response.class);

哪个更接近于文档

上传文件后，服务器会做出响应

这似乎是一个相当常见的问题，我假设这意味着我没有边界集，所以我在客户端启用了调试

DEBUG:org.apache.http.wire-这是所有Jersey连接器实现中的一个已知问题；相关的错误是。正在中跟踪修复此问题的重构

当前推荐的解决方法是简单地使用
ClientBuilder
的默认实现，它使用
java.net.HttpUrlConnection
，并正确地将所需的
boundary
值添加到
内容类型
标题。
尝试通过调用来更改
post
调用的第二个参数e> MultiPartMediaTypes.createFormData（）

。这将创建一个新的带有配置边界的

MediaType

实例，该实例将由MultiPart编写器拾取

target
    .path(path)
    .request()
    .post(Entity.entity(multipart,
                    MultiPartMediaTypes.createFormData()), Response.class);
