JaasAuthenticationHandler, SimpleTestUsernamePasswordAuthenticationHandler

public abstract class AbstractUsernamePasswordAuthenticationHandler
extends AbstractPreAndPostProcessingAuthenticationHandler

Abstract class to override supports so that we don't need to duplicate the check for UsernamePasswordCredentials.

Method Summary

protected abstract boolean	authenticateUsernamePasswordInternal(UsernamePasswordCredentials credentials) Abstract convenience method that assumes the credentials passed in are a subclass of UsernamePasswordCredentials.
protected boolean	doAuthentication(Credentials credentials) Method automatically handles conversion to UsernamePasswordCredentials and delegates to abstract authenticateUsernamePasswordInternal so subclasses do not need to cast.
protected PasswordEncoder	getPasswordEncoder() Method to return the PasswordEncoder to be used to encode passwords.
protected PrincipalNameTransformer	getPrincipalNameTransformer()
void	setClassToSupport(java.lang.Class<?> classToSupport) Method to set the class to support.
void	setPasswordEncoder(PasswordEncoder passwordEncoder) Sets the PasswordEncoder to be used with this class.
void	setPrincipalNameTransformer(PrincipalNameTransformer principalNameTransformer)
void	setSupportSubClasses(boolean supportSubClasses) Method to set whether this handler will support subclasses of the supported class.
boolean	supports(Credentials credentials) Method to check if the handler knows how to handle the credentials provided.

Method Detail

doAuthentication

protected final boolean doAuthentication(Credentials credentials)
                                  throws AuthenticationException

Method automatically handles conversion to UsernamePasswordCredentials and delegates to abstract authenticateUsernamePasswordInternal so subclasses do not need to cast.

Specified by:

doAuthentication in class AbstractPreAndPostProcessingAuthenticationHandler

Throws:

AuthenticationException

authenticateUsernamePasswordInternal

protected abstract boolean authenticateUsernamePasswordInternal(UsernamePasswordCredentials credentials)
                                                         throws AuthenticationException

Abstract convenience method that assumes the credentials passed in are a subclass of UsernamePasswordCredentials.

Parameters:

credentials - the credentials representing the Username and Password presented to CAS

Returns:

true if the credentials are authentic, false otherwise.

Throws:

AuthenticationException - if authenticity cannot be determined.

getPasswordEncoder

protected final PasswordEncoder getPasswordEncoder()

Method to return the PasswordEncoder to be used to encode passwords.

Returns:

the PasswordEncoder associated with this class.

getPrincipalNameTransformer

protected final PrincipalNameTransformer getPrincipalNameTransformer()

setClassToSupport

public final void setClassToSupport(java.lang.Class<?> classToSupport)

Method to set the class to support.

Parameters:

classToSupport - the class we want this handler to support explicitly.

setSupportSubClasses

public final void setSupportSubClasses(boolean supportSubClasses)

Method to set whether this handler will support subclasses of the supported class.

Parameters:

supportSubClasses - boolean of whether to support subclasses or not.

setPasswordEncoder

public final void setPasswordEncoder(PasswordEncoder passwordEncoder)

Sets the PasswordEncoder to be used with this class.

Parameters:

passwordEncoder - the PasswordEncoder to use when encoding passwords.

setPrincipalNameTransformer

public final void setPrincipalNameTransformer(PrincipalNameTransformer principalNameTransformer)

supports

public final boolean supports(Credentials credentials)

Description copied from interface: AuthenticationHandler

Method to check if the handler knows how to handle the credentials provided. It may be a simple check of the Credentials class or something more complicated such as scanning the information contained in the Credentials object.

Parameters:

credentials - The credentials to check.

Returns:

true if the credentials are not null and the credentials class is equal to the class defined in classToSupport.
