如何使用Spring Security自动注销

如何使用安全配置。我希望下面的配置：将工作。

applicationContext.xml

 --namespace-> xmlns:security="http://www.springframework.org/schema/security"        <security:logout invalidate-session="true"  success-handler-ref="Logout"  logout-url="/logout.html" />        </security:http>

web.xml

 <session-config>        <session-timeout> 30        </session-timeout>    </session-config>

而他们，您需要编写自己的，因为success-handler-ref =“ Logout”是
用于注销的自定义处理程序：
Logout @Component

public class Logout extends SimpleUrlLogoutSuccessHandler {    @Override    public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {        if (authentication != null) { // do something         }        setDefaultTargetUrl("/login");        super.onLogoutSuccess(request, response, authentication);}}
