Jfinal token blocker alternative implementation to prevent forms from repeating submissions

Most of the operations and jfinal are similar to the original

1. Generate tokens before jumping to view
   

Createtoken ("Jockillertoken", 30*60);

2. Add the hidden fields to the page as follows

<input type= "hidden" name= "Jockillertoken" value= "${jockillertoken}"/>

3. Define the token interceptor, which is the only point of a different place

/** * Prevent form repeat submission * @author JOCKILLER_XUCHG * */public class Tokeninterceptor implements interceptor{@Override public void I Ntercept (Invocation inv) {Boolean token = Com.jfinal.token.TokenManager.validateToken (Inv.getcontroller (), "  Jockillertoken ");  if (!token) {inv.invoke ();  }else{Inv.getcontroller (). RenderText ("Please do not repeat submissions"); } }}

If it is a duplicate commit, the Ajax callback function will accept "Please do not repeat commit"

4. On the action method of the form bar, add

Before (value = {Tokeninterceptor. class})

Test it.
