org.springframework.security.core.userdetails.UserCache

Provides a cache of {@link UserDetails} objects.

Implementations should provide appropriate methods to set their cache parameters (e.g. time-to-live) and/or force removal of entities before their normal expiration. These are not part of the UserCache interface contract because they vary depending on the type of caching system used (in-memory, disk, cluster, hybrid etc.).

Caching is generally only required in applications which do not maintain server-side state, such as remote clients or web services. The authentication credentials are then presented on each invocation and the overhead of accessing a database or other persistent storage mechanism to validate would be excessive. In this case, you would configure a cache to store the UserDetails information rather than loading it each time. @see org.springframework.security.authentication.dao.AbstractUserDetailsAuthenticationProvider @author Ben Alex

  public static void reauthenticate(final String username, final String password) {
    UserDetailsService userDetailsService = getBean("userDetailsService");
    UserCache userCache = getBean("userCache");


    UserDetails userDetails = userDetailsService.loadUserByUsername(username);
    SecurityContextHolder.getContext().setAuthentication(new UsernamePasswordAuthenticationToken(
        userDetails, password == null ? userDetails.getPassword() : password, userDetails.getAuthorities()));
    userCache.removeUserFromCache(username);
  }
