Error with cookie-value when adding a new Spring Session

Question

In my Spring Boot 1.4 based application I use Spring Session to store session data in the database with JDBC.

This works fine

Answer 1

Function cookie cannot encode properly the value with space also french signs and so on. I solve this problem with URLEncoder.encode(String arg0, Encoding version) here I used UTF-8. Here the method I created!

private static void setCookie( HttpServletResponse response, String nom, String valeur, int maxAge )throws IOException { 
    Cookie cookie = new Cookie( nom, URLEncoder.encode( valeur, "UTF-8" ) );
    cookie.setMaxAge( maxAge );
    response.addCookie( cookie );
}
