Spring 来自ManagedBean的Xhtml页面映射
下面是托管Bean类Spring 来自ManagedBean的Xhtml页面映射,spring,jsf,managed-bean,Spring,Jsf,Managed Bean,下面是托管Bean类 package Controller; import java.io.Serializable; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; import Model.Employee; @ManagedBean(name="employeeController")
package Controller;
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import Model.Employee;
@ManagedBean(name="employeeController")
@SessionScoped
public class Employeecontroller implements Serializable{
public String show(){
System.out.println("hello");
return "Login";
}
}

使用内置的AJAX支持编写自己的自定义富组件
下面是从ManagedBean映射xhtml页面的代码。
我只想当点击按钮时,登录页面将显示…但当点击按钮时,只有home.xhtml页面正在重新加载…登录页面未加载 下一个视图的选择取决于UICommand组件的action属性的值。如果导航处理程序找到具有此结果的此页面的导航规则,则下一个视图将是元素内容。若并没有类似的规则,它将查找具有值(或附加“.xhtml”文件扩展名)的页面 变化: 1.直接视图定义:
<h:commandButton action="next_page_name"/>
2.间接视图定义。在faces-config.xml中定义页面导航规则,如下所示:
<navigation-rule>
<from-view-id>/x/id_home.xhtml</from-view-id>
<navigation-case>
<from-outcome>go_to_login</from-outcome>
<to-view-id>x/login.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
如果
NavigationHandler
找不到从操作方法返回的名称为的视图,则重新加载同一页面show()
正在返回“Login”,因此您应该拥有Login.xhtml
而不是Login.xhtml
。如果它对您有效,请接受投票
public String show()
{
//...
return "x/login";
}
<navigation-rule>
<from-view-id>/x/id_home.xhtml</from-view-id>
<navigation-case>
<from-outcome>go_to_login</from-outcome>
<to-view-id>x/login.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
public String show()
{
//...
return "go_to_login";
}
