I was just about to submit a patch to the tapestry-acegi plugin app to use a
slightly different approach. My take on it is that the acegi module is
missing a utility class that would allow a user to be logged in:
1. In the AppModule, I contribute a LoginHelper service (the one I think
that should be in the tapestry-acegi plugin)
public static LoginHelper
buildLoginHelper(@InjectService("MySaltSource") SaltSourceService
saltSource,
PasswordEncoder encrypter , AuthenticationManager authManager) {
return new AcegiLoginHelper(authManager,saltSource,encrypter);
}
2. This is the login helper :
public class AcegiLoginHelper implements LoginHelper {
private final SaltSource saltSource;
private final PasswordEncoder encrypter;
private final AuthenticationManager authManager;
public AcegiLoginHelper(AuthenticationManager authManager, SaltSource
saltSource, PasswordEncoder encrypter) {
this.saltSource = saltSource;
this.encrypter = encrypter;
this.authManager = authManager;
}
public String encryptPassword(UserLogin userDetails, String plainTxtPwd)
{
return encrypter.encodePassword(plainTxtPwd,
saltSource.getSalt(userDetails));
}
public void authenticateUser(String username, String plainTxtPwd) {
UsernamePasswordAuthenticationToken authRequest = new
UsernamePasswordAuthenticationToken(username, plainTxtPwd);
try {
Authentication authentication =
authManager.authenticate(authRequest);
SecurityContextHolder.getContext().setAuthentication(authentication);
} catch (BadCredentialsException e) {
LOG.info("Failed login by user '" + username + "'.");
} catch (AuthenticationException e) {
LOG.error("Could not authenticate a user", e);
} catch (RuntimeException e) {
LOG.error(e);
e.printStackTrace();
throw e;
}
}
}
3. In the page that needs to perform the login, inject the login helper and
do something like:
loginHelper.authenticateUser(regInfo.getUsername(),
regInfo.getPassword());
For all of this, you don't need to use the tapestry-acegi plugin, it should
work with any Acegi setup, assuming that you use Salt. If you don't use
salt, customize for your needs.
