正如标题所说，我有一个服务器应用程序，它定义了这样的 RmiServiceExporter：
@Bean
RmiServiceExporter exporter() {
Class<Service> serviceInterface = Service.class;
RmiServiceExporter exporter = new RmiServiceExporter();
exporter.setServiceInterface(serviceInterface);
exporter.setService(service());
exporter.setServiceName("Service");//serviceInterface.getSimpleName());
exporter.setRegistryPort(1099);
return exporter;
}
和一个客户端应用程序，其中我有一个弹簧配置的 loginScene 和 RmiProxyFactoryBean。
这是客户端 Spring 配置：
@Configuration
public class ClientConfig {
@Bean
public Stage primaryStage() {
return new Stage();
}
@Bean
RmiProxyFactoryBean service() {
RmiProxyFactoryBean rmiProxyFactory = new RmiProxyFactoryBean();
rmiProxyFactory.setServiceUrl("rmi://127.0.0.1:1099/Service");
rmiProxyFactory.setServiceInterface(Service.class);
return rmiProxyFactory;
}
@Bean
public Scene loginScene(){
final FXMLLoader loader = new FXMLLoader(getClass().getResource("/FXMLs/LoginFXML.fxml"));
try {
return new Scene(loader.load());
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
在 LoginController 中，我有一个初始化方法，它试图从 ApplicationContext 中获取服务 bean，但是却抛出了 NoSuchBeanDefinitionException。
这是登录控制器：
@Data
public class LoginController {
private ApplicationContext factory;
private Service service;
@FXML private TextField textfield_username;
@FXML private PasswordField textfield_password;
@FXML
public void initialize(){
factory = new AnnotationConfigApplicationContext("Configurations.ClientConfig");
service = (Service) factory.getBean("service");
}
@FXML
private void textUsernameKeypressed(KeyEvent keyEvent) {
onEnterLogin(keyEvent);
}
@FXML
private void textPasswordKeypressed(KeyEvent keyEvent) {
onEnterLogin(keyEvent);
}
@FXML
private void buttonKeypressed(KeyEvent keyEvent) {
onEnterLogin(keyEvent);
}
private void onEnterLogin(KeyEvent keyEvent){
if (keyEvent.getCode().equals(KeyCode.ENTER))
login();
}
@FXML
private void loginButtonPressed(ActionEvent actionEvent) {
login();
}
private void login(){
try {
service.login(textfield_username.getText(), textfield_password.getText());
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.setContentText("Login succesfull");
alert.show();
} catch (ServiceException e) {
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.setContentText("Login failed: " + e.getMessage());
alert.show();
}
}
}
这是异常堆栈跟踪：
