JAXRS客户端设置代理

Question

我有一个Jersey客户端，当我不使用代理时，它可以正常工作。但是，当我添加代理配置时，由于以下ssl对等端关闭错误而失败。

代码段如下

try{
    final Client client = ClientBuilder.newBuilder().register(MultiPartFeature.class).build();
    client.property("http.proxyHost",proxyHost);
    client.property("http.proxyPort",proxyPort);
    final StreamDataBodyPart stream = new StreamDataBodyPart("file", inputStream);
    FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
    final MultiPart multiPart = formDataMultiPart.field("fileName", "sample").bodyPart(stream);
    if (multiPart instanceof FormDataMultiPart) {
        final FormDataMultiPart dataMultiPart = (FormDataMultiPart) multiPart;
        final WebTarget target = client.target("url");
        return target.request().header("test", "test")
                .post(Entity.entity(dataMultiPart, dataMultiPart.getMediaType()));
    }
    return null;
} catch (Exception ex) {
    log.error("Error Uploading Image", ex);
}

有人可以指出问题吗？
