BCryptPasswordEncoder-编码的密码看起来不像BCrypt

我有一个SpringBoot 2.0.1。发布mvc应用程序,这是我的配置文件

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {


    @Autowired
    private Environment env;


    @Override
    protected void configure(HttpSecurity http) throws Exception {

        final List<String> activeProfiles = Arrays.asList(env.getActiveProfiles());
        if (activeProfiles.contains("dev")) {
            http.csrf().disable();
            http.headers().frameOptions().disable();
        }

        http
                .authorizeRequests()
                .antMatchers(publicMatchers()).permitAll()
                .and()
                .formLogin().loginPage("/login").defaultSuccessUrl("/elcordelaciutat/config")
                .failureUrl("/login?error").permitAll()
                .and()
                .logout().permitAll();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

         PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
         UserDetails userDetails = User.withUsername("elcor")
                  .password(encoder.encode("elcor"))
                  .roles("ADMIN")
                  .build();
         auth.inMemoryAuthentication().withUser(userDetails);

    }


    private String[] publicMatchers() {

         /** Public URLs. */
        final String[] PUBLIC_MATCHERS = {
                "/webjars/**",
                "/css/**",
                "/js/**",
                "/images/**",
                "/",
                "/about/**",
                "/contact/**",
                "/error/**/*",
                "/console/**"
        };

        return PUBLIC_MATCHERS;

    }

}

但当我登录到该应用程序时,我在日志文件中收到了以下消息:

2018-04-11 11:27  [http-nio-5678-exec-7] WARN  o.s.s.c.b.BCryptPasswordEncoder - Encoded password does not look like BCrypt

我无法登录。。。密码正确无误。将我的应用程序从SpringBoot 1更新到SpringBoot 2后,我出现此错误
