java - 如何从数据输入字段中获取密码？

Question

WebSecurityConfig类

    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
        @Autowired
        private UserService userSevice;

        @Autowired
        private PasswordEncoder passwordEncoder;

        @Bean
        public PasswordEncoder getPasswordEncoder() {
            return new BCryptPasswordEncoder(8);
        }

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

        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userSevice)
                    .passwordEncoder(passwordEncoder);


        }

    }

用户服务类

    public class UserService implements UserDetailsService  {
        @Autowired
        private UserRepo userRepo;

        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
            User user = userRepo.findByUsername(username);
            System.out.println(username);

            if (user == null) {
                throw new UsernameNotFoundException("User not found");
            }

            return user;
        }
 }

UserDetailsService只显示用户名，但我想要它，这样我仍然可以看到将输入哪个密码，我输入system.out.printl(username)了验证，它显示，而且我不知道如何输出密码。它们取自数据库。提前谢谢。对不起我的英语

HttpServletRequest request =((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
String passwordFromForm = request.getParameter("password");
