有没有办法按照下面的方式以编程方式添加基于表单的身份验证?我正在使用我自己的LdapLoginModule. 最初我使用基本身份验证,它工作正常,但现在我想要在登录页面上进行更多控制(如显示徽标等)

有没有好的样品?

我正在使用嵌入式码头 v8.1.7 。我不为嵌入式码头使用任何 web.xml。码头服务器以编程方式启动。

<login-config>
    <auth-method>FORM</auth-method>
    <realm-name>Test JAAS Realm</realm-name>
    <form-login-config>
        <form-login-page>/login.html</form-login-page>
        <form-error-page>/error.jsp</form-error-page>
    </form-login-config>
</login-config>

创建一个FormAuthenticator并将其设置在您SecurityHandlerServletContextHandler. 这段代码创建了一个带有 2 个 servlet 的普通服务器。第一个 servlet 以 hello 消息响应已验证的用户名。第二个 servlet 实现了一个简单的登录表单。

您应该能够将代码粘贴到 a 中main[]并运行(您的类路径中需要以下 jars;jetty-serverjetty-servletjetty-security。要进行测试,请将浏览器指向http://localhost:8080,在看到 的响应之前,应提示您输入凭据(用户名/密码)hello username

Server server = new Server(8080);
ServletContextHandler context = new ServletContextHandler(server, "/", ServletContextHandler.SESSIONS | ServletContextHandler.SECURITY);

context.addServlet(new ServletHolder(new DefaultServlet() {
  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.getWriter().append("hello " + request.getUserPrincipal().getName());
  }
}), "/*");

context.addServlet(new ServletHolder(new DefaultServlet() {
  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.getWriter().append("<html><form method='POST' action='/j_security_check'>"
      + "<input type='text' name='j_username'/>"
      + "<input type='password' name='j_password'/>"
      + "<input type='submit' value='Login'/></form></html>");
    }
}), "/login");

Constraint constraint = new Constraint();
constraint.setName(Constraint.__FORM_AUTH);
constraint.setRoles(new String[]{"user","admin","moderator"});
constraint.setAuthenticate(true);

ConstraintMapping constraintMapping = new ConstraintMapping();
constraintMapping.setConstraint(constraint);
constraintMapping.setPathSpec("/*");

ConstraintSecurityHandler securityHandler = new ConstraintSecurityHandler();
securityHandler.addConstraintMapping(constraintMapping);
HashLoginService loginService = new HashLoginService();
loginService.putUser("username", new Password("password"), new String[] {"user"});
securityHandler.setLoginService(loginService);

FormAuthenticator authenticator = new FormAuthenticator("/login", "/login", false);
securityHandler.setAuthenticator(authenticator);

context.setSecurityHandler(securityHandler);

server.start();
server.join();
