Spring security 3 – How to display login errors ?

Heres how we display different error messages for the different cases of authentication failures like bad credentials, credentials expired etc.

Step 1. Configure an authentication failure handler in the application context.

Step 2. Refer this handler in the form-login node of http namespace configuration.

Step3. Capture the different URL extensions configured in step 1 in the login controller. (The example below uses Spring MVC)

Step 4. Check the attribute error in the JSP and print appropriate message for each case.

Done !
