public LogoutConfigurer()

Creates a new instance

Method Detail

addLogoutHandler

public LogoutConfigurer<H> addLogoutHandler(LogoutHandler logoutHandler)

Adds a LogoutHandler. SecurityContextLogoutHandler and LogoutSuccessEventPublishingLogoutHandler are added as last LogoutHandler instances by default.

Parameters:

logoutHandler - the LogoutHandler to add

Returns:

the LogoutConfigurer for further customization

clearAuthentication

public LogoutConfigurer<H> clearAuthentication(boolean clearAuthentication)

Specifies if SecurityContextLogoutHandler should clear the Authentication at the time of logout.

Parameters:

clearAuthentication - true SecurityContextLogoutHandler should clear the Authentication (default), or false otherwise.

Returns:

the LogoutConfigurer for further customization

invalidateHttpSession

public LogoutConfigurer<H> invalidateHttpSession(boolean invalidateHttpSession)

Configures SecurityContextLogoutHandler to invalidate the HttpSession at the time of logout.

Parameters:

invalidateHttpSession - true if the HttpSession should be invalidated (default), or false otherwise.

Returns:

the LogoutConfigurer for further customization

logoutUrl

public LogoutConfigurer<H> logoutUrl(java.lang.String logoutUrl)

The URL that triggers log out to occur (default is "/logout"). If CSRF protection is enabled (default), then the request must also be a POST. This means that by default POST "/logout" is required to trigger a log out. If CSRF protection is disabled, then any HTTP method is allowed.

It is considered best practice to use an HTTP POST on any action that changes state (i.e. log out) to protect against CSRF attacks. If you really want to use an HTTP GET, you can use logoutRequestMatcher(new AntPathRequestMatcher(logoutUrl, "GET"));

Parameters:

logoutUrl - the URL that will invoke logout.

Returns:

the LogoutConfigurer for further customization

See Also:

logoutRequestMatcher(RequestMatcher), HttpSecurity.csrf()

logoutRequestMatcher

public LogoutConfigurer<H> logoutRequestMatcher(RequestMatcher logoutRequestMatcher)

The RequestMatcher that triggers log out to occur. In most circumstances users will use logoutUrl(String) which helps enforce good practices.

Parameters:

logoutRequestMatcher - the RequestMatcher used to determine if logout should occur.

Returns:

the LogoutConfigurer for further customization

See Also:

logoutUrl(String)

logoutSuccessUrl

public LogoutConfigurer<H> logoutSuccessUrl(java.lang.String logoutSuccessUrl)

The URL to redirect to after logout has occurred. The default is "/login?logout". This is a shortcut for invoking logoutSuccessHandler(LogoutSuccessHandler) with a SimpleUrlLogoutSuccessHandler.

Parameters:

logoutSuccessUrl - the URL to redirect to after logout occurred

Returns:

the LogoutConfigurer for further customization

permitAll

public LogoutConfigurer<H> permitAll()

A shortcut for permitAll(boolean) with true as an argument.

Returns:

the LogoutConfigurer for further customizations

deleteCookies

public LogoutConfigurer<H> deleteCookies(java.lang.String... cookieNamesToClear)

Allows specifying the names of cookies to be removed on logout success. This is a shortcut to easily invoke addLogoutHandler(LogoutHandler) with a CookieClearingLogoutHandler.

Parameters:

cookieNamesToClear - the names of cookies to be removed on logout success.

Returns:

the LogoutConfigurer for further customization

logoutSuccessHandler

public LogoutConfigurer<H> logoutSuccessHandler(LogoutSuccessHandler logoutSuccessHandler)

Sets the LogoutSuccessHandler to use. If this is specified, logoutSuccessUrl(String) is ignored.

Parameters:

logoutSuccessHandler - the LogoutSuccessHandler to use after a user has been logged out.

Returns:

the LogoutConfigurer for further customizations

defaultLogoutSuccessHandlerFor

public LogoutConfigurer<H> defaultLogoutSuccessHandlerFor(LogoutSuccessHandler handler,
                                                          RequestMatcher preferredMatcher)

Sets a default LogoutSuccessHandler to be used which prefers being invoked for the provided RequestMatcher. If no LogoutSuccessHandler is specified a SimpleUrlLogoutSuccessHandler will be used. If any default LogoutSuccessHandler instances are configured, then a DelegatingLogoutSuccessHandler will be used that defaults to a SimpleUrlLogoutSuccessHandler.

Parameters:

handler - the LogoutSuccessHandler to use

preferredMatcher - the RequestMatcher for this default LogoutSuccessHandler

Returns:

the LogoutConfigurer for further customizations

permitAll

public LogoutConfigurer<H> permitAll(boolean permitAll)

Grants access to the logoutSuccessUrl(String) and the logoutUrl(String) for every user.

Parameters:

permitAll - if true grants access, else nothing is done

Returns:

the LogoutConfigurer for further customization.

init

public void init(H http)

Description copied from interface: SecurityConfigurer

Initialize the SecurityBuilder. Here only shared state should be created and modified, but not properties on the SecurityBuilder used for building the object. This ensures that the SecurityConfigurer.configure(SecurityBuilder) method uses the correct shared objects when building. Configurers should be applied here.

Specified by:

init in interface SecurityConfigurer<DefaultSecurityFilterChain,H extends HttpSecurityBuilder<H>>

Overrides:

init in class SecurityConfigurerAdapter<DefaultSecurityFilterChain,H extends HttpSecurityBuilder<H>>

configure

public void configure(H http)
               throws java.lang.Exception

Description copied from interface: SecurityConfigurer

Configure the SecurityBuilder by setting the necessary properties on the SecurityBuilder.

Specified by:

configure in interface SecurityConfigurer<DefaultSecurityFilterChain,H extends HttpSecurityBuilder<H>>

Overrides:

configure in class SecurityConfigurerAdapter<DefaultSecurityFilterChain,H extends HttpSecurityBuilder<H>>

Throws:

java.lang.Exception
