Question

我无法通过此登录表单登录，而不是登录成功页面，我得到以下

      Unable to find matching navigation case with from-view-id '/login.xhtml' for action '#{user.login}' with outcome 'login-success.xhtml?faces-redirect=true'

login.xhtml //这是登录的登录页面

面-config.xml中

          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">


   <navigation-rule>
    <from-view-id>/login.xhtml</from-view-id>
    <navigation-case>
        <from-outcome>success</from-outcome>
        <to-view-id>/login-success.jsp</to-view-id>
    </navigation-case>
    <navigation-case>
        <from-outcome>failure</from-outcome>
        <to-view-id>/login-failure.jsp</to-view-id>
    </navigation-case>
    </navigation-rule>
   </faces-config>

请帮帮我..

提前致谢

根据faces-config中的导航情况，从login方法返回“success”而不是“login-success.xhtml？faces-redirect = true”。如果要重定向，请将导航规则更改为

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

无法找到与from-view-id'/ login.xhtml'匹配的导航案例，以获取结果'login-success.xhtml'的行为'＃{user.login}'
