javax.ws.rs.ProcessingException:RESTEASY004655:无法调用请求

问题描述

我正在尝试作为客户端使用 RestEasy 3.0.19 将zip文件发布到"Restservice".这是代码:

I'm trying, as a client, to post a zip file to a "Restservice", using RestEasy 3.0.19.This is the code:

public void postFileMethod(String URL)  {
         Response response = null;
         ResteasyClient client = new ResteasyClientBuilder().build();
         ResteasyWebTarget target = client.target(URL);

         MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();

         FileBody fileBody = new FileBody(new File("C:/sample/sample.zip"),
ContentType.MULTIPART_FORM_DATA);

         entityBuilder.addPart("my_file", fileBody);
         response = target.request().post(Entity.entity(entityBuilder,
MediaType.MULTIPART_FORM_DATA));
}

我得到的错误是这个:

javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request
....
Caused by: javax.ws.rs.ProcessingException: RESTEASY003215: could not
find writer for content-type multipart/form-data type:
org.apache.http.entity.mime.MultipartEntityBuilder

我该如何解决这个问题?我查看了一些帖子，但是代码与我的代码略有不同.

How can I solve this problem? I looked into some posts, but the code is slightly different from mine.

谢谢你们.

推荐答案

您正在混合使用两个不同的HTTP客户端 RESTEasy 和 Apache HttpClient .这是仅使用RESTEasy的代码

You are mixing two different HTTP clients RESTEasy and Apache HttpClient. Here is the code which uses RESTEasy only

public void postFileMethod(String URL) throws FileNotFoundException {
    Response response = null;
    ResteasyClient client = new ResteasyClientBuilder().build();
    ResteasyWebTarget target = client.target(URL);

    MultipartFormDataOutput mdo = new MultipartFormDataOutput();
    mdo.addFormData("my_file", new FileInputStream(new File("C:/sample/sample.zip")), MediaType.APPLICATION_OCTET_STREAM_TYPE);
    GenericEntity<MultipartFormDataOutput> entity = new GenericEntity<MultipartFormDataOutput>(mdo) { };

    response = target.request().post(Entity.entity(entity,
            MediaType.MULTIPART_FORM_DATA));
}

您需要具有resteasy-multipart-provider才能使其正常工作:

You need to have resteasy-multipart-provider to have it working:

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
    <version>${resteasy.version}</version>
</dependency>
