Web application for Vehicle Sales. It's a simple application to demonstrate how to configure Spring MVC. Using Thymeleaf, Ajax, Spring Security, etc.

• No-xml Spring MVC 4 web application for Servlet 3.0 environment
• Thymeleaf, Bootstrap
• JPA 2.0 (Hibernate/HSQLDB/Spring Data JPA)
• JUnit/Mockito
• Spring Security 4.0

To install the archetype in your local repository execute following commands:

    git clone https://github.com/wkrix/Autodealer.git
    cd Autodealer
    mvn clean install

	mvn test tomcat7:run

http://localhost:8080/

username: dummySeller
password: password

• Sending AJAX request with Thymeleaf (I'm using jQuery, I didn't want to use Webflow or Tiles frameworks)

  list_customer.html

          <td>
              <button id="list-vehicles" th:attr="data-vehicle_id=${c.id}" type="button" class="btn btn-info">Info
              </button>
          </td>
          <td>
              <div th:id="resultsBlock+ ${c.id}"></div>
          </td>

   $(document).ready(function () {
          $("body").on("click", "#list-vehicles", function (e) {
              var id = $(this).attr("data-vehicle_id");
              var url = '/vehicle/list_vehicle_block/';
              url = url + id;
              $("#resultsBlock" + id).load(url);
          });
      });

  VehicleController.java

  private static final String VEHICLE_RESULT = LOCATION + "vehicle_result :: vehicleResultList";
  
  @RequestMapping(value = "/list_vehicle_block/{customerId}", method = RequestMethod.GET)
  public String showVehicleList(final Model model, @PathVariable("customerId") final int customerId) {
      model.addAttribute("resultVehicles", vehicleRepository.findByCustomerId(customerId));
      return VEHICLE_RESULT;
  }

• Prevent Brute Force authentication attempts with Spring Security

  AuthenticationFailureListener.java

  @Component
  public class AuthenticationFailureListener implements ApplicationListener<AuthenticationFailureBadCredentialsEvent> {
  
      @Autowired
      private LoginAttemptService loginAttemptService;
  
      @Override
      public void onApplicationEvent(AuthenticationFailureBadCredentialsEvent e) {
          WebAuthenticationDetails auth = (WebAuthenticationDetails) e.getAuthentication().getDetails();
          loginAttemptService.loginFailed(auth.getRemoteAddress());
      }
  }

  AuthenticationSuccessEventListener.java

  @Component
  public class AuthenticationSuccessEventListener implements ApplicationListener<AuthenticationSuccessEvent> {
  
      @Autowired
      private LoginAttemptService loginAttemptService;
  
      @Override
      public void onApplicationEvent(AuthenticationSuccessEvent e) {
          WebAuthenticationDetails auth = (WebAuthenticationDetails) e.getAuthentication().getDetails();
          loginAttemptService.loginSucceeded(auth.getRemoteAddress());
      }
  
  }

  SigninController.java

  ```java
     @RequestMapping(value = "signin")
            public String signin() {
                final String ip = request.getRemoteAddr();
                if (loginAttemptService.isBlocked(ip)) {
                    throw new LoginException("Bad login. IP BAN.");
                }
                return LOCATION;
            }
  ```
  

• Change the user interface language by clicking the country flags

  lang-change.js

       $(document).ready(function () {
           $("#en_flag").on("click", function () {
               updateParam("lang", "en");
           });
           $("#hu_flag").on("click", function () {
               updateParam("lang", "hu");
           });
       });
       
       function updateParam(key, value) {
           var q = String(location.search);
       
           if (q.length > 0) {
               if (q.indexOf(key) > -1) {
                   var regExpPattern = key + "=([a-zA-Z]+)?";
                   var regExp = new RegExp(regExpPattern);
       
                   q = q.replace(regExp, key + "=" + value);
               } else {
                   q += "\u0026" + key + "=" + value;
               }
           } else {
               q += "?" + key + "=" + value;
           }
       
           location.search = q;
   }

  WebAppConfiguration.java

      @Bean
      public LocaleResolver localeResolver() {
          SessionLocaleResolver slr = new SessionLocaleResolver();
          return slr;
      }
  
      @Bean
      public LocaleChangeInterceptor localeChangeInterceptor() {
          LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
          lci.setParamName("lang");
          return lci;
      }
  
      @Override
      public void addInterceptors(InterceptorRegistry registry) {
          registry.addInterceptor(localeChangeInterceptor());
      }

• Sending e-mail messages with Spring by configuring JavaMail API with JavaMailSenderImpl

  MailConfiguration.java

      @Configuration
      @PropertySource("classpath:mail.properties")
      public class MailConfiguration {
      
          @Value("${mail.protocol}")
          private String protocol;
          @Value("${mail.host}")
          private String host;
          @Value("${mail.port}")
          private int port;
          @Value("${mail.smtp.auth}")
          private boolean auth;
          @Value("${mail.smtp.starttls.enable}")
          private boolean starttls;
      
          @Bean
          public JavaMailSender javaMailSender() {
              JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
              Properties mailProperties = new Properties();
              mailProperties.put("mail.smtp.auth", auth);
              mailProperties.put("mail.smtp.starttls.enable", starttls);
              mailSender.setJavaMailProperties(mailProperties);
              mailSender.setHost(host);
              mailSender.setPort(port);
              mailSender.setProtocol(protocol);
              return mailSender;
          }

  EmailService.java

      @Service
      public class EmailService {
          
              @Autowired
              private JavaMailSender mailSender;
          
              @Autowired
              private TemplateEngine templateEngine;
          
              @Autowired
              private HttpServletRequest request;
          
              @Autowired
              private HttpServletResponse response;
          
              @Autowired
              private MessageSource messageSource;
          
              @Autowired
              private Environment environment;
          
              public void sendSimpleMail(final Customer loadedCustomer, final Vehicle vehicle) throws MessagingException {
          
                  // Prepare the evaluation context
                  final Locale locale = RequestContextUtils.getLocale(request);
                  final WebContext ctx = new WebContext(request, response, request.getServletContext(), locale);
                  ctx.setVariable("name", loadedCustomer.getName());
                  ctx.setVariable("sellDate", new Date());
                  ctx.setVariable("vehicleName", vehicle.getVehicleName());
                  ctx.setVariable("vehicleColor", vehicle.getColor());
                  ctx.setVariable("vehicleType", vehicle.getType());
          
                  // Prepare message using a Spring helper
                  final MimeMessage mimeMessage = mailSender.createMimeMessage();
                  final MimeMessageHelper message = new MimeMessageHelper(mimeMessage, "UTF-8");
                  String subject = messageSource.getMessage("email.subject", null, locale);
                  message.setSubject(subject);
                  message.setFrom(environment.getProperty("mail.from"));
                  message.setTo(loadedCustomer.getEmail());
          
                  // Create the HTML body using Thymeleaf
                  final String htmlContent = templateEngine.process("mails/email_simple", ctx);
                  message.setText(htmlContent, true);
          
                  String host = environment.getProperty("mail.host");
                  if (!environment.getProperty("mail.host").equals("")) {
                      // Send email
                      this.mailSender.send(mimeMessage);
                  }
              }
          }

[Note1: No additional services are required in order to start the application. Although you can configure the SMTP server for sending e-mail messages in mail.properties as mail.host.]

[Note2: You can ignore SchemaExport errors. Combination of create-drop and in-memory database produces these for every database object it tries to drop. Reason being that there is not any database objects to remove - DROP statements are executed against empty database. Also with normal permanent database such an errors do come, because Hibernate does not figure out before executing DROP statements does added object exist in database or is it new.]
