登录 View :

@UIScope
@SpringView(name=ViewTokens.SIGNIN)
public class LoginView extends VerticalLayout implements View {

@Autowired
AccountRepository accountRepository;

private static final float PANEL_WIDTH = 440;
private static final float PANEL_HEIGHT = 260;
private static final float COMPONENT_WIDTH = 260;
private static final float COMPONENT_HEIGHT = 45;

private ComponentHelper componentHelper;
private Notification errorNotify;
private Panel loginPanel;
private FormLayout loginForm;
private TextField loginField;
private PasswordField passwordField;
private Button signInButton;

public LoginView() {
    initComponents();
    buildLoginView();
}

protected void initComponents() {
<ommitted>
}

private void buildLoginView() {
   <ommitted>
}

public void signIn(Button.ClickEvent event) {
    doSignIn(loginField.getValue(), passwordField.getValue());
    loginField.clear();
    passwordField.clear();
}

private void doSignIn(String username, String password) {
    <omitted>
    Account account = accountRepository.findByUsername(loginField.getValue(), passwordField.getValue());
    Notification.show(account.toString());
}

    @Override
    public void enter(ViewChangeListener.ViewChangeEvent viewChangeEvent) {
    }
}

到目前为止我已经尝试使用 setter 方法 - 仍然没有结果。

P.S 这可能会有所帮助 - 在应用程序启动时，我的 spring 数据会初始化 schema.sql 和 data.sql 脚本。

似乎您缺少使用 @Repository 注释 com.reborn.simtrade.backend.repositories.AccountRepository，如:

package com.reborn.simtrade.backend.repositories;

import org.springframework.stereotype.Repository;

@Repository
public class AccountRepository{

}
