hello1代码：

   package javaeetutorial.hello1;
   import javax.enterprise.context.RequestScoped;
   import javax.inject.Named;
   @Named
   @RequestScoped
   public class Hello {
   private String name;
    }
   public String getName() {
     }
   public void setName(String user_name) {
        this.name = user_name;
     }
    }

package 引入包名
@named @requestscoped 用修饰器方法进行方法诸如
public class hello 定义hello类 里面的大括号内：实现功能的代码 获取name等
