spring - 将用户保存在数据库中，Spring Security 注册表单

Question

我正在学习 Spring Security。无法保存注册用户（如果他至少在注册，因为我不知道）

网络安全配置：

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/", "/registration").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
                .logout()
                .permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userService)
                .passwordEncoder(NoOpPasswordEncoder.getInstance());
    }

用户实体：

@Entity
@Getter
@Setter
@ToString
@EqualsAndHashCode(of = "id")
public class User implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String username;
    private String password;
    @ElementCollection(targetClass = Role.class, fetch = FetchType.EAGER)
    @CollectionTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"))
    @Enumerated(EnumType.STRING)
    Set<Role> roles;
    ...constructors
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return getRoles();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

控制器：

    @GetMapping("/registration")
    public String registration(){

        return "registration";
    }
    @PostMapping("/registration")
    public String addUser(User user, Map<String, Object> model) {
        User userFromDb = userRepository.findByUsername(user.getUsername());
        if (userFromDb != null) {
            model.put("message", "User exists!");
            return "registration";
        }
        user.setRoles(Collections.singleton(Role.USER));
        userRepository.save(user);

        return "redirect:/login";

百里香叶：你好：

<form th:action="@{/logout}" method="post">
    <input type="submit" value="Sign Out"/>
</form>

登录：

<div th:if="${param.error}">
    Invalid username and password.
</div>
<div th:if="${param.logout}">
    You have been logged out.
</div>
<form th:action="@{/login}" method="post">
    <div><label> User Name : <input type="text" name="username"/> </label></div>
    <div><label> Password: <input type="password" name="password"/> </label></div>
    <div><input type="submit" value="Sign In"/></div>
</form>

登记：

<form action="/login" method="post">
    <div><label>User Name: <input type="text" name="username"></label></div>
    <div><label>Password: <input type="text" name="username"></label></div>
    <div><input type="submit" value="Sign in"></div>
</form>
<a href="/registration">Add new User</a>

我不知道我必须在哪里修复（在表单的前端或后端） 我的注册表到底发生了什么以及如何添加“保存用户”？

如果可能的话，我想知道，thymeleaf/freemaker/mustache 和我必须使用哪一个之间有什么区别？
