Double-click the Hello.java file to view it.
The Hello class, called a managed bean class, provides getter and setter methods for the name property used in the Facelets page expressions. By default, the expression language refers to the class name, with the first letter in lowercase (hello.name).
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;
}
}If you use the default name for the bean class, you can specify @Model as the annotation instead of having to specify both @Named and @RequestScoped. The @Model annotation is called a stereotype, a term for an annotation that encapsulates other annotations. It is described later in Using Stereotypes in CDI Applications. Some examples will use @Model where it is appropriate.

在Hello类，称为管理bean类，提供了getter和setter方法name中的Facelets页面表达式中使用属性。默认情况下，表达式语言引用类名，第一个字母为小写（hello.name）。
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;
}
}
