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:runhttp://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.]
