server.servlet.session.timeout: 30m

@Component

        // 获取当前请求的URL
        String requestUrl = event.getRequest().getRequestURL().toString();
        
        // 根据不同的URL重定向到不同的JSP页面
        if (requestUrl.contains("/page1")) {
            event.getResponse().sendRedirect("/page1.jsp");
        } else if (requestUrl.contains("/page2")) {
            event.getResponse().sendRedirect("/page2.jsp");
        } else {
            event.getResponse().sendRedirect("/default.jsp");
        }
    }
}
