Question

我是Java EE的新手。所以我找不到解决方案！你有没有想出来的？

会话Bean：

package services;

import javax.ejb.Stateless;
import javax.ejb.LocalBean;

@Stateless
@LocalBean
public class HelloService {

    public String getHelloString() {
        return "Hello";
    }
}

管理bean：

package beans;

import javax.ejb.EJB;
import javax.inject.Named;
import javax.enterprise.context.RequestScoped;
import services.HelloService;

@Named(value = "helloBean")
@RequestScoped
public class HelloBean {
    @EJB
    private HelloService helloService;


    private String hello;

    public HelloBean() {
    }

    public String getHello() {
        hello = helloService.getHelloString();
        return hello;
    }

    public void setHello(String hello) {
        this.hello = hello;
    }

}

但是在index.xhtml中没有输出！ Maven已成功构建，页面已在浏览器中打开。但没有输出！

没有输出从Session Bean通过Managed bean显示到JSF页面
