BCryptPasswordEncoder - 编码密码看起来不像BCrypt

我有一个SpringBoot 2.0.1.RELEASE 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;

    }

}

但是当我登录到应用程序时,我在日志文件中收到了此消息:

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

Spring Security在版本5中引入了一些重大更改。其中一个是在哈希中包含用于散列密码的算法。这样可以更轻松地迁移。

密码的一般格式为:

{id}encodedPassword 

作为旁注:如果您将密码存储在数据库中并设置了确切的修复长度,这也可能导致您无意中截断哈希末尾的情况,因为前面的ID是长度散列的增加。

我还将一个项目从Spring Boot 1 / Spring 4迁移到Spring Boot 2 / Spring 5,然后从BCrypt迁移到PBKDF2。

我的密码编码器现在看起来像这样:

public PasswordEncoder passwordEncoder() {
    // This is the ID we use for encoding.
    String currentId = "pbkdf2.2018";

    // List of all encoders we support. Old ones still need to be here for rolling updates
    Map<String, PasswordEncoder> encoders = new HashMap<>();
    encoders.put("bcrypt", new BCryptPasswordEncoder());
    encoders.put(currentId, new Pbkdf2PasswordEncoder(PBKDF2_2018_SECRET, PBKDF2_2018_ITERATIONS, PBKDF2_2018_HASH_WIDTH));

    return new DelegatingPasswordEncoder(currentId, encoders);
}

它还需要更新数据库并为所有当前哈希值添加{bcrypt}前缀(我以前只使用过BCrypt)
