How to logout user(not current) by login?

Question

I have 2 roles in my system: user and admin

admin can logout any user by name.

How can I do this? I need something like this:

service.logoutUser(anotherUserName)

config looks like this:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers
                 ....
                .formLogin()
                .loginProcessingUrl("/api/login")
                .successHandler(authenticationSuccessHandler)
                .failureHandler(new SimpleUrlAuthenticationFailureHandler())
                .and()
            .rememberMe()
                .key("...")
                .rememberMeCookieName("...")
                .userDetailsService(userDetailsService)
                .and()
            .csrf()
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
                .and()
            .logout()
                .deleteCookies("JSESSIONID")
                .logoutUrl("/logout")
                .logoutSuccessHandler(new HttpStatusReturningLogoutSuccessHandler())
                .permitAll();

Something like this:

import org.springframework.security.core.userdetails.User;
...
...
Set<SimpleGrantedAuthority> userRoles = new HashSet<>();
userRoles.add(new SimpleGrantedAuthority("ROLE_USER"));
User user = new User(anotherUserName, "", userRoles);
List<SessionInformation> sessions = sessionRegistry.getAllSessions(u, false);

for(SessionInformation info : infos) {
   info.expireNow();
}
