Spring MVC Security LDAP Authentication Hibernate Authorization Java Config

STEP 1:- To perform database authentication, you have to create tables to store the users and roles detail.

Here are the MySQL scripts to create users and user_roles tables.
  • Table: users
CREATE  TABLE users (
  username VARCHAR(60) NOT NULL ,
  password VARCHAR(60) NOT NULL ,
  enabled TINYINT NOT NULL DEFAULT 1 ,
  PRIMARY KEY (username));

  • Table: user_roles
CREATE TABLE user_roles (
  user_role_id int(11) NOT NULL AUTO_INCREMENT,
  username varchar(60) NOT NULL,
  role varchar(60) NOT NULL,
  PRIMARY KEY (user_role_id),
  UNIQUE KEY uni_username_role (role,username),
  KEY fk_username_idx (username),
  CONSTRAINT fk_username FOREIGN KEY (username) REFERENCES users (username));


  • here is insert script
insert into users values('user','123456',1)
insert into users values('apiuser','123456',1)
insert into users values('admin','123456',1)

insert into user_roles values('user','ROLE_USER')
insert into user_roles values('admin','ROLE_USER')
insert into user_roles values('admin','ROLE_ADMIN')
insert into user_roles values('admin','ROLE_API')
insert into user_roles values('apiuser','ROLE_USER')
insert into user_roles values('apiuser','ROLE_API')

STEP 2:- Open Eclipse and Create Dynamic Web Project named SpringSecurityHrbridLdapJavaConfig

STEP 3:- Make sure you use Target Runtime as Apache Tomcat 7.0 and Dynamic web module version as 3.0..

STEP 4:- copy below jars to WEB-INF/lib folder.
  • antlr-2.7.6.jar

STEP 5:- Create Spring DataSource configuration file.
  • Package: com.tutorialsdesk.config
  • Filename: DataSourceConfig.java
package com.tutorialsdesk.config;

import java.util.Properties;

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBuilder;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
public class DataSourceConfig {

 private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
 private static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
 private static final String PROPERTY_NAME_DATABASE_URL = "db.jdbcurl";
 private static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";

 @Resource
 private Environment env;
 
 @Bean
 public DataSource dataSource() {
 DriverManagerDataSource dataSource = new DriverManagerDataSource();
 dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
 dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
 dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
 dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));
 
 return dataSource;
 }
 
 @Bean
 public SessionFactory sessionFactory() {
 LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource());
 builder.scanPackages("com.tutorialsdesk.model").addProperties(getHibernateProperties());

 return builder.buildSessionFactory();
 }
 
 private Properties getHibernateProperties() {
 Properties prop = new Properties();
 prop.put("hibernate.format_sql", "true");
 prop.put("hibernate.show_sql", "true");
 prop.put("hibernate.connection.pool_size", "5");
 prop.put("hibernate.hbm2ddl.auto", "update");
 prop.put("hibernate.dialect",
"org.hibernate.dialect.SQLServerDialect");
 return prop;
 }
 
 @Bean
 public HibernateTransactionManager transactionManager() {
 return new HibernateTransactionManager(sessionFactory());
 }
 
}

STEP 6:- Create db.properties file under WEB-INF/db.properties.
db.driver=com.mysql.jdbc.Driver
db.jdbcurl=jdbc:mysql://localhost:3306/test
db.username=root
db.password=password

STEP 7:- Create Spring Security configuration fileas below.
  • Package: com.tutorialsdesk.config

org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import
org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import
org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.ldap.userdetails.LdapAuthoritiesPopulator;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 
 @Autowired
 private DataSource dataSource;
 
 @Autowired
 @Qualifier("ldaploginService")
 LdapAuthoritiesPopulator ldapAuthoritiesPopulator;
 
 @Autowired
 public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
 auth.ldapAuthentication()
 .contextSource()
 .ldif("/WEB-INF/conf/users.ldif").root("o=tutorialsdesk")
 //.url("ldap://LDAPURL:PORT/dc=corp,dc=tutorialsdesk,dc=com")
 //.managerDn("CN=Prakash,OU=Service Accounts,OU=Privilege User
Account,DC=corp,DC=tutorialsdesk,DC=com")
 //.managerPassword("Password")
 .and()
 .userSearchFilter("(uid={0})")
 .userSearchBase("ou=users")
 // .userSearchBase("dc=corp,dc=tutorialsdesk,dc=com")
 // .userSearchFilter("(&(objectClass=user)(sAMAccountName={0}))");
 .ldapAuthoritiesPopulator(ldapAuthoritiesPopulator);
 }
 
 @Override
 protected void configure(HttpSecurity http) throws Exception {

 http
 .authorizeRequests()
 .antMatchers("/").permitAll()
 .antMatchers("/home").access("hasRole('ROLE_USER')")
 .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
 .antMatchers("/api/**").access("hasRole('ROLE_ADMIN') or
hasRole('ROLE_API')")
 .and()
 .formLogin()
 .loginProcessingUrl("/login")
 .loginPage("/login")
 .failureUrl("/login?error")
 .defaultSuccessUrl("/home")
 .usernameParameter("username")
 .passwordParameter("password")
 .and()
 .exceptionHandling()
 .accessDeniedPage("/Access_Denied");
 
 }
 
}

STEP 8:- Create a class extends AbstractSecurityWebApplicationInitializer, it will load the springSecurityFilterChain automatically.

 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();
 
 System.out.println("HelloWorldController.getPrincipal()" +
SecurityContextHolder.getContext().getAuthentication().getAuthorities().size());
 
 System.out.println("HelloWorldController.getPrincipal()" +
