Question

我正试图通过Jersey REST Client发布一些formdata和多部分文件。我为jersey客户端添加了以下依赖项：

<dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-client</artifactId>
        <version>1.9</version>
    </dependency>

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.9</version>
    </dependency>

    <dependency>
        <groupId>com.sun.jersey.contribs</groupId>
        <artifactId>jersey-multipart</artifactId>
        <version>1.9</version>
    </dependency>

我的POST控制器方法如下：

@RequestMapping(value = "/formdata/submit", method = RequestMethod.POST)
public String postFormData(@ModelAttribute String formData, 
@RequestParam("file) MultipartFile file, Model model, HttpServletRequest 
request, HttpServletResponse response)
{
try
{
    ObjectMapper mapper = new ObjectMapper();
    String jsonData = mapper.writeValueAsString(formData);
    String postUrl = getPostUrl();

    ClientConfig config = new DefaultClientConfig();
    com.sun.jersey.api.client.Client client = 
    com.sun.jersey.api.client.Client.create(config);
    WebResource webResource = client.resource(postUrl);

    ClientResponse responseMsg = webResource
        .queryParam("jsonData", jsonData)
        .queryParam("file", file.toString())
        .post(ClientResponse.class);
}
catch (Exception e)
{
    return "error";
}
return "success";
}

My Spring MVC REST控制器接受多部分文件，如下所示：

@Consumes(MediaType.MULTIPART_FORM_DATA)
@RequestMapping(value = "/save-comment", method = RequestMethod.POST)
public String addComment(@FormDataParam("jsonData") String jsonData, 
@FormDataParam("file") MultipartFile file, ModelMap model)
{
    //My Logic to save file and data
}

当我尝试将数据和文件一起发布到我的Spring MVC REST Controller方法时，我的泽西客户端帖子给了我一个错误。

我收到错误：

我需要使用com.sun.jersey在multipart文件中发布formdata 我能够使用org.glassfish.jersey.media找到一些建议，但没有找到我正在寻找的任何建议。

通过Jersey REST Client使用multipart文件POST formdata
