Spring MVC security with custom login form example using XML configuration

STEP 1:- Open Eclipse and Create Dynamic Web Project named SpringSecurityCustomFormXMLConfig.

STEP 2:- Make sure you use Target Runtime as Apache Tomcat 7.0. 

STEP 3:- copy below jars to WEB-INF/lib folder.
  • commons-logging-1.2.jar
  • spring-aop-4.1.4.RELEASE.jar
  • spring-beans-4.1.4.RELEASE.jar
  • spring-context-4.1.4.RELEASE.jar
  • spring-core-4.1.4.RELEASE.jar
  • spring-expression-4.1.4.RELEASE.jar
  • spring-security-config-4.0.2.RELEASE.jar
  • spring-security-core-4.0.2.RELEASE.jar
  • spring-security-web-4.0.2.RELEASE.jar
  • spring-web-4.1.4.RELEASE.jar
  • spring-webmvc-4.1.4.RELEASE.jar
STEP 4:- Create Spring Configuration Bean file. /WebContent/WEB-INF/dispatcher-servlet.xml
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:mvc="http://www.springframework.org/schema/mvc" 
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="
 http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans.xsd
 http://www.springframework.org/schema/mvc 
 http://www.springframework.org/schema/mvc/spring-mvc.xsd
 http://www.springframework.org/schema/context 
 http://www.springframework.org/schema/context/spring-context.xsd">
 
 <context:component-scan base-package="com.tutorialsdesk.controller" />
 
 <bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
 <property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
 <property name="prefix" value="/WEB-INF/views/" />
 <property name="suffix" value=".jsp" />
 </bean>
 
 <mvc:annotation-driven/>
 
</beans>

STEP 5:- Create Spring security configuration file. /WebContent/WEB-INF/spring-security.xml
<beans:beans xmlns="http://www.springframework.org/schema/security"
 xmlns:beans="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans.xsd
 http://www.springframework.org/schema/security 
 http://www.springframework.org/schema/security/spring-security.xsd">
 
 <http auto-config="true" >
 <intercept-url pattern="/" access="permitAll" />
 <intercept-url pattern="/home"
access="hasRole('USER')" />
 <intercept-url pattern="/admin**"
access="hasRole('ADMIN')" />
 <intercept-url pattern="/api**" access="hasRole('ADMIN')
or hasRole('API')" />
 
 <access-denied-handler error-page="/Access_Denied" />
 
 <form-login 
 login-processing-url="/login"
 login-page="/loginPage" 
 default-target-url="/home" 
 username-parameter="username"
 password-parameter="password"
 authentication-failure-url="/loginPage?error"/> 
 </http>
 
 <authentication-manager >
 <authentication-provider>
 <user-service>
 <user name="user" password="123456"
authorities="ROLE_USER" />
 <user name="admin" password="123456"
authorities="ROLE_USER,ROLE_ADMIN,ROLE_API" />
 <user name="apiuser" password="123456"
authorities="ROLE_USER,ROLE_API" />
 </user-service>
 </authentication-provider>
 </authentication-manager>
 
</beans:beans>

STEP 6 :- Map Spring configuration files in /WebContent/WEB-INF/web.xml file as below :-
<?xml version="1.0" encoding="UTF-8"?>
<web-app 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xmlns="http://java.sun.com/xml/ns/javaee" 
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
 version="3.0">
 
 <display-name>SpringSecurityCustomFormXMLConfig</display-name>
 
 <servlet>
 <servlet-name>dispatcher</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <load-on-startup>1</load-on-startup>
 </servlet>
 
 <servlet-mapping>
 <servlet-name>dispatcher</servlet-name>
 <url-pattern>/</url-pattern>
 </servlet-mapping>
 
 <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>/WEB-INF/spring-security.xml</param-value>
 </context-param>
 
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
 
 <filter>
 <filter-name>springSecurityFilterChain</filter-name>
 <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
 </filter>
 
 <filter-mapping>
 <filter-name>springSecurityFilterChain</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
 
</web-app>

STEP 7 :- Create Controller Class.
  • Package: com.tutorialsdesk.controller
  • Filename: HelloWorldController.java
package com.tutorialsdesk.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import
org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class HelloWorldController {

 @RequestMapping(value = { "/", "/loginPage" }, method =
RequestMethod.GET)
 public String loginPage(ModelMap model, @RequestParam(value = "error",
required = false) String error) {
 
 if (error != null) {
 model.addAttribute("error", "Invalid Username or Password !!!");
 }
 return "login";
 }
 
 @RequestMapping(value = { "/home" }, method = RequestMethod.GET)
 public String homePage(ModelMap model) {
 model.addAttribute("greeting", "Hi, Welcome to mysite. ");
 return "welcome";
 }
 
 @RequestMapping(value = "/admin", method = RequestMethod.GET)
 public String adminPage(ModelMap model) {
 model.addAttribute("user", getPrincipal());
 return "admin";
 }
 
 @RequestMapping(value = "/api", method = RequestMethod.GET)
 public String dbaPage(ModelMap model) {
 model.addAttribute("user", getPrincipal());
 return "api";
 }
 
 @RequestMapping(value="/logout", method = RequestMethod.GET)
 public String logoutPage (ModelMap model,HttpServletRequest request,
HttpServletResponse response) {
 Authentication auth = SecurityContextHolder.getContext().getAuthentication();
 if (auth != null){ 
 new SecurityContextLogoutHandler().logout(request, response, auth);
 }
 model.addAttribute("msg", "You've been logged out
successfully.");
 return "login";
 }
 
 @RequestMapping(value = "/Access_Denied", method = RequestMethod.GET)
 public String accessDeniedPage(ModelMap model) {
 model.addAttribute("user", getPrincipal());
 return "accessDenied";
 }
 
 private String getPrincipal(){
 String userName = null;
 Object principal =
SecurityContextHolder.getContext().getAuthentication().getPrincipal();
 
 if (principal instanceof UserDetails) {
 userName = ((UserDetails)principal).getUsername();
 } else {
 userName = principal.toString();
 }
 return userName;
 }
}


STEP 8 :- Create jsp files in /WebContent/WEB-INF/views folder
  • Filename: login.jsp
<%@ taglib prefix="c"
uri="http://java.sun.com/jsp/jstl/core"%>
<%@page session="true"%>

<head>
<title>Login Page</title>
<style>
.error {
 padding: 15px;
 margin-bottom: 20px;
 border: 1px solid transparent;
 border-radius: 4px;
 color: #a94442;
 background-color: #f2dede;
 border-color: #ebccd1;
}

.msg {
 padding: 15px;
 margin-bottom: 20px;
 border: 1px solid transparent;
 border-radius: 4px;
 color: #31708f;
 background-color: #d9edf7;
 border-color: #bce8f1;
}

#login-box {
 width: 300px;
 padding: 20px;
 margin: 100px auto;
 background: #fff;
 -webkit-border-radius: 2px;
 -moz-border-radius: 2px;
 border: 1px solid #000;
}
</style>
</head>
<body onload='document.loginForm.username.focus();'>

 <h1>Spring Security Custom Login Form</h1>

 <div id="login-box">

 <h2>Login with Username and Password</h2>

 <c:if test="${not empty error}">

type="submit"
 value="submit" /></td>
 </tr>
 </table>

 <input type="hidden" name="${_csrf.parameterName}"
 value="${_csrf.token}" />

 </form>
 </div>

</body>
</html>
