Question

我在Glassfish服务器（GF4）上实现了一个REST服务，还有一个小客户端程序来测试它。但服务器响应“状态415 - 不支持的媒体类型”错误。请查看我的代码并给我一些提示。

服务器代码：

import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;
import javax.ws.rs.PathParam;
import javax.ws.rs.Consumes;
import javax.ws.rs.Path;
import javax.ws.rs.POST;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.mail.MessagingException;
import javax.ws.rs.GET;

@Path("generic")
public class GenericResource {

    @Context
    private UriInfo context;

    public GenericResource() {
        System.out.println("Mediatype: "+MediaType.MULTIPART_FORM_DATA);
    }

    @Path("post")
    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public void postXml(javax.mail.internet.MimeMultipart multiPart) {
        try {
            System.out.println(multiPart.getCount());
        } catch (MessagingException ex) {
            Logger.getLogger(GenericResource.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

这是我的客户代码：

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.apache.commons.io.FileUtils;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.HttpClientBuilder;

public class URLTester {
    public static void main(String[] args) throws Exception {
        URLTester http = new URLTester();
        http.sendPost();
    }

    // HTTP POST request
    private void sendPost() throws Exception {
        String filename = "C:\\development\\java\\URLTester\\test.obx";
        String xml = readXML(filename);
        String url = "http://localhost:8080/RESTgarbio2oex/webresources/generic/post";

        HttpClient httpclient = HttpClientBuilder.create().build();
        HttpPost post = new HttpPost(url);

        // MultiPart POST
        FileBody fb = new FileBody(new File(filename));

        post.setHeader("Content-type", "multipart/form-data");
        MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
        multipartEntity.addPart("file", fb);
        multipartEntity.addTextBody("data", "Here is the data.");
        post.setEntity(multipartEntity.build());

        HttpResponse response = httpclient.execute(post);
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        String inputLine;
        while ((inputLine = rd.readLine()) != null) {
            System.out.println(inputLine.toString());
        }
    }

    private String readXML(String xmlsource) {
        String xml = "";
        try {
            File in = new File(xmlsource);
            xml = FileUtils.readFileToString(in);
        } catch (IOException ex) {
            Logger.getLogger(URLTester.class.getName()).log(Level.SEVERE, null, ex);
        }
        return xml;
    }    
}

如您所见，我将内容类型设置为"multipart/form-data"，并使用MultipartEntityBuilder创建要发送的数据。我还使用Apache HTTPClientBuilder类将数据发布到服务器。

在服务器端，根本没有调用postXml方法，即使我的调试控制台说调用了构造函数并将Mediatype: multipart/form-data作为结果。

如果您需要更多信息，请告诉我。我搜索了很多网站，但没有遇到我的问题的解决方案。提前谢谢。
