我尝试将jsf和spring集成，但是tomcat有错误404。我真的很困惑，我找不到问题所在。我将 default.xhtml 放在 web-content 中，但 tomcat 说：description 请求的资源（/jsfandspring/faces/default.xhtml）不可用。UserBoImpl.java

package p;

public class UserBoImpl implements UserBo{
    String name;

    public void setName(String name) {
        this.name = name;
    }

    public String getMessage() {

        return "hi: " + name;

    }
}

用户Bean.java

package p;
import java.io.Serializable;

import p.UserBo;

//DI via JSF managed bean
public class UserBean implements Serializable{

    //DI via Spring
    UserBo userBo;

    public void setUserBo(UserBo userBo) {
        this.userBo = userBo;
    }

    public String printMsgFromSpring() {

        return userBo.getMessage();

    }

}

我上面的听众有这个警告：

Class org.springframework.web.jsf.el.SpringBeanFacesELResolver must extend the type javax.el.ELResolver

我的问题在哪里。我找不到它。
