Java JSF2.1Spring3.0集成

根据我在网上搜索的示例，我正在尝试进行非常简单的Spring3+JSF2.1集成

这是我的代码：

我的HTML已提交给actionController.actionSubmitted（）方法：

现在我的豆子春天：

public interface MailService {
    void sendUserMail(User user);
}

public class MailServiceImpl implements MailService{

    @Override
    public void sendUserMail(User user) {
        System.out.println("Mail to "+user.getEmail()+" sent." );

    }
}

这是我的web.xml

 <listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
  </listener>
  <listener>
    <listener-class>
        org.springframework.web.context.request.RequestContextListener
    </listener-class>
  </listener>

  <!-- Welcome page -->
  <welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
  </welcome-file-list>

  <!-- JSF mapping -->
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

我为邮件服务添加了getter，问题就解决了。我不知道为什么需要此getter，但它可以工作。

您好，请给我示例链接，我想进行类似的集成。@Jsword，没问题：如果getter不存在，variablesolver找不到“属性”。

public interface MailService {
    void sendUserMail(User user);
}

public class MailServiceImpl implements MailService{

    @Override
    public void sendUserMail(User user) {
        System.out.println("Mail to "+user.getEmail()+" sent." );

    }
}

 <listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
  </listener>
  <listener>
    <listener-class>
        org.springframework.web.context.request.RequestContextListener
    </listener-class>
  </listener>

  <!-- Welcome page -->
  <welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
  </welcome-file-list>

  <!-- JSF mapping -->
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
