Question

我有3个jsf页面：欢迎页面：index.xhtml 第二页：displayall.xhmtl包含第三页的命令链接：login_jsf.xhtml

问题是，当我按导航器返回按钮时，它会重定向到欢迎页面，而不是displayall.xhtml

这是我用来重定向的标签：

   <p:commandLink id="login" action="login_jsf?faces-redirect=true" style="margin-right:20px">
                <h:outputText value="Se connecter" />
            </p:commandLink>

我的web.xml

向 faces-config.xml 添加导航规则（注意“重定向”标记）：

<navigation-rule>
    <from-view-id>displayall.xhtml</from-view-id>
    <navigation-case>
        <from-outcome>login</from-outcome>
        <to-view-id>login.xhtml</to-view-id>
        <redirect />
    </navigation-case>
</navigation-rule>

或创建导航处理程序bean并从commandLink调用其相关方法：

@Named
@RequestScoped
public class NavigationHandler implements Serializable {
   public String moveToLoginPage() {
      return "login?faces-redirect=true";
   }
}

然后：

<p:commandLink id="login" action="#{navigationHandler.moveToLoginPage}"> 
          <h:outputText value="Se connecter" />
</p:commandLink>

jsf返回欢迎页面而不是上一页
