Jersey客户端抛出javax.ws.rs.ProcessingException:java.net.ConnectException:无法连接到/127.0.0.1（端口8080）

我正在使用一个Android jersey客户端，它向web服务发送表单。我越来越

javax.ws.rs.ProcessingException:java.net.ConnectException:未能 连接到/127.0.0.1（端口8080）：连接失败：ECONREFUSE （连接被拒绝）

我没有配置任何代理。 我可以通过邮递员使用网络服务（浏览器也会显示）。
到目前为止，我看到的SO帖子都在谈论代理或服务器处于非活动状态，这在我看来都是不真实的。
用于连接到web服务的我的android客户端代码：

public class SignUpAction implements Runnable {
    private Client client;
    private WebTarget webTarget;
    private Form form;   
    private RegistrationBeanInterface rbI;         
    @Override
    public void run() {
        client = JerseyClientBuilder.newClient();
        try {
            webTarget = client.target(new URI("http://127.0.0.1:8080/WebApp/User/Register"));
            form = new Form();

            Response response = webTarget.request(MediaType.APPLICATION_FORM_URLENCODED).post(Entity.form(form)); 
            this.statusCode = response.getStatus();
        } catch (URISyntaxException e) {
            e.getReason();
        }
    }    
    public int getStatusCode(){
        return this.statusCode;
    }
}

这就是我在活动中如何调用连接类：

signUpAction = signUpAction.createSignUpAction();
executorService.execute(signUpAction);
statusCode = signUpAction.getStatusCode();
if(statusCode == 200){
   Intent intent = new Intent(this, SignInActivity.class);
   startActivity(intent);
}

我对泽西的Gradle依赖

implementation 'org.glassfish.hk2.external:javax.inject:2.4.0-b06'    
implementation('org.glassfish.jersey.containers:jersey-container-servlet:2.25.1') {
        exclude module : 'javax.inject'
    }

这是我的stacktrace：
