Spring Security Part 1 – Simple Login application with database

What is Spring Security?

Spring security is a framework that provides security solution, handling authentication and authorization at both the web request level and the method level. Spring security handle security in two ways. One is secure web request and other one is restrict access at the URL level. Spring security uses servlet filters.

In this post I’m going to create a simple web application that handle the login authentication and authorization.

Download project : http://www.mediafire.com/?bb9x88uxvkb0uuv or http://dl.dropbox.com/u/7215751/JavaCodeGeeks/SpringSecurityTutorialPart1/spring-security-login-example.rar

Before create the project need to execute some queries to mysql to create a new database , tables and add some sample data.

create-table.sql

 CREATE DATABASE IF NOT EXISTS `spring-test`;  
 -- create user  
 CREATE USER 'user'@'localhost' IDENTIFIED BY 'test';  
 GRANT ALL ON spring-test.* TO 'user'@'localhost';  
 USE `spring-test`;  
 CREATE TABLE USER_DETAILS (  
 USERNAME VARCHAR(10) NOT NULL,  
 PASSWORD VARCHAR(32) NOT NULL,  
 PRIMARY KEY (USERNAME)  
 );  
 CREATE TABLE USER_AUTH (  
 USERNAME VARCHAR(10) NOT NULL,  
 AUTHORITY VARCHAR(10) NOT NULL,  
 FOREIGN KEY (USERNAME) REFERENCES USER_DETAILS(USERNAME)  
 ); 

test-data.sql

 insert into USER_DETAILS values ('user','123');  
 insert into USER_DETAILS values ('admin','admin');  
 insert into USER_AUTH values ('user', 'ROLE_USER');  
 insert into USER_AUTH values ('admin', 'ROLE_ADMIN');  

After that I create a web project using maven and add below dependencies to pom.xml

<properties>
        <spring.version>3.0.5.RELEASE</spring.version>
</properties> 
<dependencies>  
     <dependency>

   </dependencies>  

After that change the web.xml like this

 <!DOCTYPE web-app PUBLIC  
     '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN'  
     'http://java.sun.com/dtd/web-app_2_3.dtd' >

   </servlet>  
   <servlet-mapping>  
     <servlet-name>login</servlet-name>

   </servlet-mapping>  
   <listener>  
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
   </listener>  
   <context-param>  
     <param-name>contextConfigLocation</param-name>  
     <param-value>  
       /WEB-INF/login-servlet.xml,  
       /WEB-INF/login-security.xml,  
       /WEB-INF/login-service.xml  
     </param-value>  
   </context-param>  
   <!-- Spring Security -->  
   <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>  
   <welcome-file-list>  
     <welcome-file>login.jsp</welcome-file>  
   </welcome-file-list>  
 </web-app> 

Now I need to create login-servlet.xml, login-security.xml and login-service.xml spring configuration files. In this example we are using c3p0 connection pool with Mysql database.

Here is the login-servlet.xml file

 <?xml version='1.0' encoding='UTF-8'?>

The login.jsp page looks like this. (Need to place is under webapp directory. But not in under WEB_INF directory)

 <%@ taglib prefix='c' uri='http://java.sun.com/jsp/jstl/core' %>  
 <html>  
 <head>  
   <title>Login</title>  
 </head>  
 <body>  
 <c:if test='${not empty param.error}'>  
   <font color='red'>  
     Login error. <br />  
     Reason : ${sessionScope['SPRING_SECURITY_LAST_EXCEPTION'].message}  
   </font>  
 </c:if>  
 <form method='POST' action='<c:url value='/j_spring_security_check' />'>  
   <table>  
     <tr>  
       <td align='right'>Username</td>  
       <td><input type='text' name='j_username' /></td>  
     </tr>  
     <tr>  
       <td align='right'>Password</td>  
       <td><input type='password' name='j_password' /></td>  
     </tr>  
     <tr>  
       <td colspan='2' align='right'>  
         <input type='submit' value='Login' />  
       </td>  
     </tr>  
   </table>  
 </form>  
 </body>  
 </html>

home.jsp page

 <%@ taglib prefix='c' uri='http://java.sun.com/jsp/jstl/core' %>  
 <%@ taglib prefix='sec' uri='http://www.springframework.org/security/tags' %>  
 <html>  
 <head>  
   <title>Home</title>  
 </head>  
 <body>  
   <a href=<c:url value='/j_spring_security_logout'/>>Logout</a><br/>  
   <sec:authorize ifAnyGranted='ROLE_ADMIN'>  
     <h1>Only admin can see this</h1><br/>  
     <a href='admin'> Admin Home </a>  
   </sec:authorize>  
   <h1>Welcome</h1>  
 </body>  
 </html>  

admin-home.jsp page

 <%@ taglib prefix='c' uri='http://java.sun.com/jsp/jstl/core' %>  
 <%@ page contentType='text/html;charset=UTF-8' language='java' %>  
 <html>  
 <head>  
   <title>Admin</title>  
 </head>  
 <body>  
   <a href=<c:url value='/j_spring_security_logout'/>>Logout</a><br/>  
   <h1>Only Admin allowed here</h1>  
 </body>  
 </html>  

After that you need to write two controller to retrieve home page and admin-home page. Here is the HomeController.java

 package rd.controller;  
 import org.springframework.stereotype.Controller;  
 import org.springframework.ui.Model;  
 import org.springframework.web.bind.annotation.RequestMapping;  
 import org.springframework.web.bind.annotation.RequestMethod;  
 @Controller  
 public class HomeController {  
   @RequestMapping(value = '/home' , method = RequestMethod.GET)  
   public String setUp(Model model){  
     return 'home';  
   }  
 }  

Here is the AdminController.java

 package rd.controller;  
 import org.springframework.stereotype.Controller;  
 import org.springframework.ui.Model;  
 import org.springframework.web.bind.annotation.RequestMapping;  
 import org.springframework.web.bind.annotation.RequestMethod;  
 @Controller  
 public class AdminController {  
   @RequestMapping(value = '/admin' , method = RequestMethod.GET)  
   public String setUp(Model model){  
     return 'admin-home';  
   }  
 }  

That’s it. Run mvn clean install command to create war file. Copy the war file under tomcat/webapps directory and access the web app in your favorite browser.
url : localhost:<port>/spring-login/login.jsp

Test case 1 : Try to log with user as username 123 as password. You will get users home page.
Test case 2 : Try to log with admin as username admin as password. You will get users home page with visible admin page link.

In spring security part 2 I will modify this project and add remember me feature and md5 password encryption feature.

In near future Ill try to post some interesting article about spring security with CAS integration and LDAP integration. Stay tuned :)
