How can I add my own logout handler to LogoutFilter in spring-security ? Thanks!
The following solution works for me and may be helpful:
Extend the SimpleUrlLogoutSuccessHandler or implement the LogoutHandler:
public class LogoutSuccessHandler extends SimpleUrlLogoutSuccessHandler {
// Just for setting the default target URL
public LogoutSuccessHandler(String defaultTargetURL) {
this.setDefaultTargetUrl(defaultTargetURL);
}
@Override
public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
// do whatever you want
super.onLogoutSuccess(request, response, authentication);
}
}
Add to your Spring Security Configuration:
<security:logout logout-url="/logout" success-handler-ref="logoutSuccessHandler" />
<bean id="logoutSuccessHandler" class="your.package.name.LogoutSuccessHandler" >
<constructor-arg value="/putInYourDefaultTargetURLhere" />
</bean>
See the answer in this post in the Spring Security Forum:
<beans:bean id="logoutFilter" class="org.springframework.security.ui.logout.LogoutFilter">
<custom-filter position="LOGOUT_FILTER"/>
<beans:constructor-arg index="0" value="/logout.jsp"/>
<beans:constructor-arg index="1">
<beans:list>
<beans:ref bean="securityContextLogoutHandler"/>
<beans:ref bean="myLogoutHandler"/>
</beans:list>
</beans:constructor-arg>
</beans:bean>
<beans:bean id="securityContextLogoutHandler" class="org.springframework.security.ui.logout.SecurityContextLogoutHandler"/>
<beans:bean id="myLogoutHandler" class="com.whatever.CustomLogoutHandler">
<beans:property name="userCache" ref="userCache"/>
</beans:bean>
public class CustomLogoutHandler implements LogoutHandler {
private UserCache userCache;
public void logout(final HttpServletRequest request, final HttpServletResponse response, final Authentication authentication) {
// ....
}
@Required
public void setUserCache(final UserCache userCache) {
this.userCache = userCache;
}
}
