Configuring Logout in Spring Security

We will change the applicationContext-security.xml of our login example, to configure logout.
we will add logout tag in the http Section.

<http auto-config="true" access-denied-page="/deniedPage.jsp">
    <intercept-url pattern="/securePage**" access="ROLE_ADMIN" />
    <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />
    <form-login login-processing-url="/j_spring_security_check"
                login-page="/login.jsp"
                default-target-url="/securePage.jsp"
                authentication-failure-url="/login.jsp" />
    <logout    logout-url="/j_spring_security_logout" invalidate-session="true" logout-success-url="/login.jsp" />
</http>

It is obvious from the configuration that session will be invalidated and login page will be displayed after logout.
