创建一个FormAuthenticator
并将其设置在您SecurityHandler
的ServletContextHandler
. 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-server
和jetty-servlet
)jetty-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();
