Redirect user to login page on timeout Spring Secu

问题:

I am using Spring Core version 4.1.6 and Spring security 4.0.1.

I want to redirect user to login page on timeout.

So far after some research, I implemented ApplicationListener<HttpSessionDestroyedEvent> and I can now successfully intercept timeouts and logouts.

I have HttpSessionDestroyedEvent object in onApplicationEvent function. This object dont seem to have any method from where I can redirect user or return login model object. My question is how can I redirect user to login page?

I have seen this url but it doesn't intercepts timeouts. My question is more focused towards timeouts.

There are several approaches for this. first you can use spring security auto config in your applicationContext.xml by setting login-page it will automatically redirect not logged-in users reaching secured routes (like /userReged/**) to that certain login-page :

<security:http auto-config="true">
    <security:intercept-url pattern="/admin/**" access="ROLE_ADMIN"/>
    <security:intercept-url pattern="/userReged/**" access="ROLE_USER"/>
    <security:form-login
            login-page="/"
            default-target-url="/somePage"
            authentication-failure-url="/user/logfailed?error"
            username-parameter="userName"
            password-parameter="userPassword" />
    <security:logout
            logout-success-url="/?logout"/>
</security:http>

one other way is to check user being logged-in in your controller manually in specific route :

@RequestMapping("/somePage")
public String getSomePage(Model model, HttpServletRequest request) {

    Principal principal = request.getUserPrincipal();
    if (principal != null) {

        User activeUser = userService.getUserByPhone(principal.getName());
        // ...

    } else { // user is not authenticated
        System.out.println("user is not authenticated to proceed the somePage!!!!!!!");
        return "redirect:/";
    }
}

In order to set timeout for spring security you can put this in your web.xml :

<session-config>
    <session-timeout>
        1440
        <!--mins-->
    </session-timeout>
</session-config>

now if you want to redirect clients on exact timeout you can refresh the page automatically in client side in some intervals.
