I would advise you to start with the spring-boot, security, jpa, velocity.
By structure:
(1) Main controller - description of the main page front through ModelMap.@RequestMapping(value = "", method = {RequestMethod.GET, RequestMethod.HEAD})
public String MainPage(ModelMap model) {
model.addAttribute("title_page", "Чат сервер");
final User user = securityService.findLoggedIn();
if (user != null) {
model.addAttribute("authuser", user);
}
MainContent(model, domain);
GeneratePageBlock(model, "/site/" + domain + "/pages/main.vm");
return "/site/" + domain + "/index";
}
(2) Registration/repetition control, implementation of interface JpaRepository<User, Long> for the processing of user data where User Interface implementation UserDetails ♪ @Entity
@Table(name = "user")
public class User implements UserDetails {
@Id
@GeneratedValue(generator = "increment")
@GenericGenerator(name = "increment", strategy = "increment")
@Column(name = "id")
private Long id;
@Column(name = "enabled")
private Boolean enabled;
@NotEmpty(message = "Заполните поле")
@Column(name = "username")
private String username;
@NotEmpty(message = "Заполните поле")
@Email(message = "Неверный формат Email")
@Column(name = "email")
private String email;
@NotEmpty(message = "Заполните поле")
@Size(min = 4, message = "Пароль должен содержать минимум {min} символа")
@Column(name = "password")
private String password;
@Transient
private String passwordConfirm;
@Column(name = "roles")
private String roles;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public void setEnabled(Boolean enabled) {
this.enabled = enabled;
}
@Override
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPasswordConfirm() {
return passwordConfirm;
}
public void setPasswordConfirm(String passwordConfirm) {
this.passwordConfirm = passwordConfirm;
}
public String getRoles() {
return roles;
}
public void setRoles(String roles) {
this.roles = roles;
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return enabled;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
if (roles != null) {
if (roles.contains("ADMIN")) {
return AuthorityUtils.createAuthorityList("ROLE_ADMIN", "ROLE_MODERATOR", "ROLE_USER");
} else if (roles.contains("MODERATOR")) {
return AuthorityUtils.createAuthorityList("ROLE_MODERATOR", "ROLE_USER");
}
}
return AuthorityUtils.createAuthorityList("ROLE_USER");
}
}
Example logic of the controller - @RequestMapping(value = "registration", method = RequestMethod.POST)
public String registration(@ModelAttribute("user") User user, BindingResult result,
ModelMap model, HttpServletRequest request) {
model.addAttribute("title_page", "Регистрация - База знаний Lineage 2 Helios");
MainContent(model, domain);
userValidator.validate(user, result);
if (result.hasErrors()) {
GeneratePageBlock(model, "/site/" + domain + "/pages/registration.vm");
return "/site/" + domain + "/index";
}
final User user1 = new User();
user1.setUsername(user.getUsername());
user1.setEmail(user.getEmail());
user1.setPassword(new BCryptPasswordEncoder().encode(user.getPassword()));
user1.setEnabled(false);
user1.setRoles("ROLE_USER");
userService.save(user1);
final User user_saved = userService.findByUsername(user1.getUsername());
eventPublisher.publishEvent(new OnRegistrationCompleteEvent(user_saved, getAppUrl(request)));
model.addAttribute("message", "Регистрация прошла успешно, информация отправлена на Email: " + user.getEmail());
GeneratePageBlock(model, "/site/" + domain + "/pages/registrationSuccessful.vm");
return "/site/" + domain + "/index";
}
