private Claims extractAllClaims(String token){
   return Jwts
             .parser()
             .verifyWith(getSignInKey())
             .build()
             .parseSignedClaims(token)
             .getPayload();
}

private Foo extractFoo(String token){
    Claims claims = extractAllClaims(token);
    return claims.getFoo();
}

private Bar extractBar(String token){
    Claims claims = extractAllClaims(token);
    return claims.getBar();
}

Is the code above or below good practice to extract data and why? Thanks for your contribute!

private Date extractFoo(String token){
    Claims claims = Jwts
                .parser()
                .verifyWith(getSignInKey())
                .build()
                .parseSignedClaims(token)
                .getPayload();
    return claims.getFoo();
}

private Date extractBar(String token){
    Claims claims = Jwts
                .parser()
                .verifyWith(getSignInKey())
                .build()
                .parseSignedClaims(token)
                .getPayload();
    return claims.getBar();
}

On top we will be bearing with jwts’ chain once, but on bottom each time we extract something.
