Question

我尝试使用faces-config.xml文件中的navigation-rule进行重定向，但我遇到问题我没有被重定向到index.xhtml页面的welcome.xhtml页面单击登录按钮后。在login() bean中调用了validateUser()以及LoginBeanCDI，结果我得到了seccuss，但没有发生重做。

我在从表单操作goToWelcome()调用后，在LoginBeanCDI bean中使用注释<h:commandButton value="Login" id="combtn"action="#{loginBeanCDI.goToWelcome()}"/>测试页面的funktioniliy，在这种情况下，我被重定向到welcome.xhtml页面没有任何问题。因此，我认为问题在于faces-config.xml文件中的导航规则。

的index.xhtml

Answer 1

导航案例中有拼写错误。

更改

 <from-action>#{loginBeanCBI.login()}</from-action>

要

 <from-action>#{loginBeanCDI.login()}</from-action>

JSF不会与导航案例重定向
