![]() For password encoding we are using BCrypt password encoder. We will configure realm name and authentication entry point. In spring security configuration we are using HTTP basic authentication. UserDetails userDetails = (UserDetails)new User(activeUserInfo.getUserName(),ĪctiveUserInfo.getPassword(), Arrays.asList(authority)) GrantedAuthority authority = new SimpleGrantedAuthority(activeUserInfo.getRole()) UserInfo activeUserInfo = userInfoDAO.getActiveUser(userName) Import class MyAppUserDetailsService implements UserDetailsService IUserInfoDAO UserDetails loadUserByUsername(String userName) Import .userdetails.UsernameNotFoundException Import .authority.SimpleGrantedAuthority We fetch username, password and roles from the database that is used by spring UserDetailsService to authenticate the user. To authenticate user using database, we need to implement it and override loadUserByUsername() method. Implement UserDetailsService UserDetailsService loads user authentication and authorization related data. Import class UserInfo implements Serializable 3. ('tarun', '$2a$10$2Y52/hoWr4I5ePxK7D2Pi8q', 'Tarun Singh', 'ROLE_USER', 'India', 1) įind a main class to generate BCrypt password. ('mukesh', '$2a$10$N0eqNiuikWCy9ETQ1rdau.XEELcyEO7kukkfoiNISk/9F7gw6eB0W', 'Mukesh Sharma', 'ROLE_ADMIN', 'India', 1), INSERT INTO `users` (`username`, `password`, `full_name`, `role`, `country`, `enabled`) VALUES Dumping data for table ers: ~2 rows (approximately) (3, 'Spring MVC with Hibernate', 'Spring') INSERT INTO `articles` (`article_id`, `title`, `category`) VALUES Dumping data for table concretepage.articles: ~3 rows (approximately) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=latin1 `article_id` int(5) NOT NULL AUTO_INCREMENT, Dumping structure for table concretepage.articles This section covers annotations that you can use when you test Spring applications. Dumping database structure for concretepageĬREATE DATABASE IF NOT EXISTS `concretepage` Now we will provide complete example step by step. Client will send user credential encoded with Base64 using username:password token in HttpHeaders for every request. In our MVC configuration we will use Jackson2 message converter to indent JSON output. We have integrated BCrypt password encoding with UserDetailsService in our example. For security purpose request should be HTTPS and password should be stored in encoded form in database. ![]() ![]() When the HTTP header request for authentication is received user is authenticated and if an unauthenticated request is received then it is handled by BasicAuthenticationEntryPoint and HTTP status code (401) is sent back with the header information that contains authentication scheme as Basic authentication. To perform header based Basic authentication, we need to use BasicAuthenticationEntryPoint and override its commence() method that will return HTTP status code (401) and authentication scheme as Basic authentication. It will return proper HTTP status code in HTTP header and JSON output in response body. In the controller class we will create methods that will map URL and HTTP method to accept request. Our DAO will use JPA EntityManager to perform database operations. Our service layer will be protected by spring annotation. We will perform create, read, update and delete (CRUD) operation. In our example we will create two demo applications, one with java configuration and other with XML configuration. For authentication we will use Basic authentication scheme using HTTP header. Now running all the tests, all successed.Īt the end, as you can instantly see the most painless way to get access to the authenticated user is by the it all the code written in this post can be found on GitHub.Spring 4We will create a Spring REST web service security application that will be authenticated using JPA with Hibernate and MySQL database. (Take note that we can't use any implementation of UserDetails, for security reasons.). With the second endpoint, we access to the security context by the static method "getContext()", then we cast the Principle to "UserDetails" to obtain more information like expiration, authorities, etc. Securit圜ontext context = Securit圜ontextHolder. The above annotation consents us to inject the current authenticated Userdetails or Principle to the method as a parameter. So let's break it down : UserDetails user With two endpoints : ( "/user" ) public class UserController So first thing, we create a UserController If you would like to start from scratch, you can download the starting code base from springInitializr (we will use security and web dependencies). In this post we are going to see, how to get the current authenticated user, in our spring project, using two different methods so let's start.
