package javaeetutorial.hello1;

import javax.enterprise.context.RequestScoped;
import javax.inject.Named;

@Named
@RequestScoped
public class Hello {

private String name;

public Hello() {
}

public String getName() {
return name;
}

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

首先引入注解包，分别为Named和requestScoped接口

Named 可绑定多个实现，RequestScoped指定实现类的作用域

然后就是实现类的三个方法，私有成员变量

构造函数，获取和设置成员变量
