Question

我正在使用JSF 2.1和Maven构建基于ICEmobile的Web应用程序。当我的jsf页面没有查找它的bean但我仍然可以构建和部署没有错误的项目时，我遇到了这个问题，我通过Eclipse中的运行配置部署项目：clean tomcat7:run-war。即使我通过注释或applicationContext.xml声明bean，页面仍然没有正确调用bean。我可以在bean中获取字段的值，但无法调用该bean中的方法System.out.println("Pressed");不向控制台提供输出。我猜它必须与我的配置有关，但我不知道在哪里查看。请给我一些提示。感谢

The Bean：

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.event.ActionEvent;

@ManagedBean(name = ButtonBean.BEAN_NAME)
@SessionScoped
public class ButtonBean implements Serializable {

    private static final long serialVersionUID = 1L;

    public static final String BEAN_NAME = "buttonBean";

    private String buttonName = "0";

    public String getButtonName() {
        return buttonName;
    }

    public void setButtonName(String buttonName) {
        this.buttonName = buttonName;
    }

    public void buttonPress(ActionEvent event){
        System.out.println("Pressed");
        String buttonState = (String)event.getComponent().getAttributes().get("buttonState");
        if (buttonState.equals("change") && buttonName.equals("0")) buttonName = "1";
        else if (buttonState.equals("change") && buttonName.equals("1")) buttonName = "0";
    }  
}
