Question

当我使用无效帐户登录时，会显示错误页面，但是当帐户有效时，登录页面会被重定向...这是否在我的代码中？

这是我的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

        <role-name>user</role-name>
    </security-role>
</web-app>

这是index.xhtml（欢迎页面），重定向到两个页面之一（Login.xhtml或CreateAdmin.xhtml）：

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:ui="http://java.sun.com/jsf/facelets">
    <h:head>
        <title>Sign in </title>
        <h:outputStylesheet name="css/jsfcrud.css"/>
    </h:head>

 <f:view>
<ui:insert name="metadata"/>
<f:event type="preRenderView" listener="#{mngsession.methodInManagedBean()}" />
<h:body></h:body>
</f:view>
</html>

这是函数：从索引调用methodInManagedBean：

 public void methodInManagedBean() throws IOException, ClassNotFoundException, SQLException {
        int mmbrexist = 0;
        Class.forName("oracle.jdbc.driver.OracleDriver");
        Connection connection = null;
        connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE", "hr", "remoteusers");
        Statement stmt = null;
        String query = "select USERID  from users";
        try {
            stmt = connection.createStatement();
            ResultSet rs = stmt.executeQuery(query);
            while (rs.next()) {
                mmbrexist++;

            }
            // >
            if (mmbrexist > 0) { 
                nav.performNavigation("/Login.xhtml");
            } else {
                nav.performNavigation("/CreatingAdmin.xhtml");
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            if (stmt != null) {
                stmt.close();
                connection.close();
            }
        }

    }

这是login.xhtml：

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      xmlns:h="http://xmlns.jcp.org/jsf/html">
    <h:head>
        <title>Sign in </title>
        <h:outputStylesheet name="css/jsfcrud.css"/>
    </h:head>



    <style type="text/css" >
        td { text-align:left; font-family: verdana,arial; color: #064073; font-size: 1.00em; }
        input { border: 1px solid #CCCCCC; border-radius: 5px; color: #666666; display: inline-block; font-size: 1.00em;  padding: 5px; width: 100%; }
        input[type="button"], input[type="reset"], input[type="submit"] { height: auto; width: auto; cursor: pointer; box-shadow: 0px 0px 5px #0361A8; float: right; text-align:right; margin-top: 10px; margin-left:7px;}
        //form.center { margin-left:auto; margin-right:auto; }
        .error { font-family: verdana,arial; color: #D41313; font-size: 1.00em; }
        form { margin: 0 auto; width:500px;}
    </style>
    <h:body>

        <form action="j_security_check" method="POST">
            <table border="0">
                <tbody>
                    <tr>
                        <td slign="right">Username: &nbsp;</td>
                        <td><input type="text" name="j_username" value="" /></td>
                    </tr>
                    <tr>
                        <td slign="right">Password: &nbsp;</td>
                        <td><input type="password" name="j_password" value="" /></td>
                    </tr>
                    <tr>
                        <td></td>
                        <td><input type="submit" value="Login" /></td>
                    </tr>
                </tbody>
            </table>

        </form>

    </h:body>



</html>

我正在使用Glassfish进行FORM身份验证，并且我已经配置了一个名为bob的域名（如web.xml中所示）

成功登录后，我无法进入下一个JSF页面
