According to spring security 5.0 's new feature. They write this.

Spring Security’s PasswordEncoder interface is used to perform a one way transformation of a password to allow the password to be stored securely. Given PasswordEncoder is a one way transformation, it is not intended when the password transformation needs to be two way (i.e. storing credentials used to authenticate to a database). Typically PasswordEncoder is used for storing a password that needs to be compared to a user provided password at the time of authentication.

So i tried this Mutiple HttpSecurity. This s my security configuration. Hope it help you.

@Configuration
@EnableWebSecurity
public class SecurityConfig
{
  private final EdminService edminService;
  public SecurityConfig ( final EdminService edminService ){
    this.edminService=edminService;
  }
  @Bean
  public UserDetailsService userDetailsService() throw Exception {
    UserBuilder users= Users.withDefaultPasswordEncoder;
    InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
    List edminList=this.edminService.findAll();
    for(EdminEntity edmin: edminList){
     manager.createUser(users.username(edmin.getEdminname())
     .password(edmin.getEdminrpass()).roles("EDMIN_ROLE").build());
    }
    return manager;
  }
  @Configuration
  @Order(1)
  public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
    protected void configure(HttpSecurity http) throws Exception {
       http
       .authorizeRequests()
       .antMatchers("/home","/vendor/**","/image/**","/home/**").permitAll()
       .antMatchers("/admin/**").hasRole("EDMIN_ROLE")
       .anyRequest().authenticated()
       .and()
       .formLogin()
       .loginPage("/login")
       .permitAll()
       .defaultSuccessUrl("/home")
       .and()
       .logout()
       .logoutRequestMatcher(new AntPathRequestMatcher("/logout"));}
   }
}
