Question

我正在努力使用JAX-RS编写的REST服务。

我想使用以下代码创建和绑定客户端：

final String DEFAULT_RESOURCE_URL = "http://someURL:8180/";

    try {
        ResteasyClient client = new ResteasyClientBuilder().build().register(ClientResponseLoggingFilter.class);

        ResteasyWebTarget target = client.target(DEFAULT_RESOURCE_URL).path(
                "service/document/getdrawingbrowser/{documentId}/{documentType}/{partDocumentId}/{documentVersion}/{userName}");

        HashMap<String, Object> keyValuesMap = new HashMap<String, Object>();

        keyValuesMap.put("documentId", "xxxx");
        keyValuesMap.put("documentType", "yyy");
        keyValuesMap.put("partDocumentId", "000");
        keyValuesMap.put("documentVersion", "000");
        keyValuesMap.put("userName", "user");

        Builder responseBuilder = target.resolveTemplates(keyValuesMap).request();
        Response response = responseBuilder.get();


        if (response.getStatus() == 200) {

            byte[][] documents = response.readEntity(byte[][].class);
            for (int i = 0; i < documents.length; i++) {
                displayProperties(documents[i]);
            }
        } else {
            Object entity = response.getEntity();
            System.out.println(entity);
        }

    } catch (Throwable e) {
        e.printStackTrace();
    }
}

REST-Service正确响应我想：

status: 200
date: Mon Sep 14 10:53:02 CEST 2015
last-modified: null
location: null
headers:
    Connection :keep-alive, 
    Content-Disposition :attachment; filename=someFile.pdf, 
    Content-Type :application/octet-stream, 
    Date :Mon, 14 Sep 2015 08:53:02 GMT, 
    Server :WildFly/8, 
    Transfer-Encoding :chunked, 
    X-Powered-By :Undertow/1, 
media-type: application

但是在第102行byte[][] documents = response.readEntity(byte[][].class);我得到的javax.ws.rs.ProcessingException说：

javax.ws.rs.ProcessingException: Unable to find a MessageBodyReader of content-type application/octet-stream and type class [[B

我已经尝试了几个.jar文件以及here和here的一些方法，但遗憾的是，它们都没有成功...

有什么想法吗？

无法找到内容类型application / octet-stream的MessageBodyReader
