Question

我正在尝试在netbeans的JEE应用程序中编写登录页面。因此，我创建了：login.jsp，login_error.jsp和admin / admin.jsp页面。

login.jsp

    <%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Authenticate User</title>
    </head>
    <body>
        <h1>Please enter Username and Password to access admin Page</h1>
        <form method="POST" action="j_security_check">
            <table>
                <tr>
                    <td>Username:</td>
                    <td><input type="text" name="j_username"></td>
                </tr>
                <tr>
                    <td>Password:</td>
                    <td><input type="password" name="j_password"></td>
                </tr>
                <tr>
                    <td></td>
                    <td><input type="submit" value="Submit"></td>
                </tr>
            </table>
        </form>
    </body>
</html>

login_error.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Authenticate Error</title>
    </head>
    <body>
        <h3 style="color:red">There was an error loggin in. Please try once again...</h3>
        <form method="POST" action="j_security_check">
            <table>
                <tr>
                    <td>Username:</td>
                    <td><input type="text" name="j_username"></td>
                </tr>
                <tr>
                    <td>Password:</td>
                    <td><input type="password" name="j_password"></td>
                </tr>
                <tr>
                    <td></td>
                    <td><input type="submit" name="login"></td>
                </tr>
            </table>
        </form>
    </body>
</html>

我在部署文件 web.xml

中进行了必要的配置

<?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">
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    <security-constraint>
        <display-name>Admin Page Constraint</display-name>
        <web-resource-collection>
            <web-resource-name>Administrative Pages</web-resource-name>
            <description/>
            <url-pattern>/admin/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <description/>
            <role-name>admin</role-name>
        </auth-constraint>
    </security-constraint>
    <login-config>
        <auth-method>FORM</auth-method>
        <realm-name>file</realm-name>
        <form-login-config>
            <form-login-page>/login.jsp</form-login-page>
            <form-error-page>/login_error.jsp</form-error-page>
        </form-login-config>
    </login-config>
    <security-role>
        <description/>
        <role-name>admin</role-name>
    </security-role>
</web-app>

，以及 glassfish-web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app error-url="">
  <security-role-mapping>
    <role-name>admin</role-name>
    <group-name>appadmin</group-name>
  </security-role-mapping>
  <class-loader delegate="true"/>
  <jsp-config>
    <property name="keepgenerated" value="true">
      <description>Keep a copy of the generated servlet class' java code.</description>
    </property>
  </jsp-config>
</glassfish-web-app>

在管理控制台中（相对于glassfish5），我在security-> realms-> file中创建一个新用户，名称为=“ admin”，密码=“ 0000”和用户组=“ appadmin”。问题是，当我尝试测试应用程序时，每次输入正确的用户名/密码或错误的用户名/密码时，都会出现错误页面。有人可以帮我解决这个问题吗？谢谢

使用glassfish5进行基于表单的身份验证失败
