我在 Errai Jax-rs 上遇到问题，我不确定为什么这不起作用：

@Path("userservice")
public interface UserService {
    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public void login(LoginForm login);
}

当从 UI 调用时：

    service.call(new RemoteCallback<Void>() {
        @Override
        public void callback(Void response) {
                         // Do stuff        
        }
    }, new ErrorCallback() {
        @Override
        public boolean error(Message message, Throwable throwable) {
            return false;
        }
    }).login(new LoginForm(this.username.getText(),
            this.password.getText(),
            true));

引发此错误：

尝试通过 RestEasy 访问服务时遇到相同的异常。因此，以防其他人偶然发现它：

正如 Andreas 已经提到的，它通常指的是错误的 URL。

就我而言，我可以通过 Postman 或 resteasy 目标调用我的服务

final String path = "http://localhost:8080/repository/user";

例如

        Client client = ClientBuilder.newBuilder().build();
        WebTarget target = client.target("http://localhost:8080/repository/user");
        Response response = target.request().get();

在使用 Resteasy-Proxy 时，我必须使用

final String path = "http://localhost:8080/repository";

例如

    ResteasyClient client = new ResteasyClientBuilder().build();
    ResteasyWebTarget target = client.target(UriBuilder.fromPath("http://localhost:8080/repository"));
    IUserTestRepository proxy = target.proxy(IUserTestRepository.class);

发生此错误通常是因为 rest/endpoint 地址不可用：

  1. 检查类名上方的@Path注解
  2. 检查方法名称上方的@Path注解

  3. 如果您使用@PathParam或@QueryParam注释，请确保两件事：

    • 该值对应于方法签名中声明的类型
    • 检查您是否传递了正确数量的参数
    • 所有注解导入实际上来自包javax.ws.rs

如果错误仍然存​​在，请尝试检查您的 CORS 实现（如果有）。

尝试使用错误数量的参数访问我的方法时出现此异常。

我打了电话：http://localhost:8080/my-app/my-service/param1

而服务期望：http://localhost:8080/my-app/my-service/param1/param2
