Aujourd'hui, j'ai regardé la corrélation des nombres aléatoires,J'ai trouvé cette classe par inadvertance.

Ça a l'air super,Il y a un héritage.SecurityRandom,Encore.ThreadLocalMots,A - t - il les caractéristiques des deux,Est devenu un combinateur?
Voyons voir.
Voyons d'abord comment il génère des nombres aléatoires
@Override
public int nextInt() {
return random().nextInt();
}
Suivi,On dirait.randomL'approche est qu'elle est au cœur.
private static Random random() {
return PlatformDependent.threadLocalRandom();
}
PlatformDependent- Oui.nettyEn bas,On en reparlera plus tard.
Suivi
public static Random threadLocalRandom() {
return RANDOM_PROVIDER.current();
}
Suivi
private interface ThreadLocalRandomProvider {
Random current();
}
Suivi,Oh, mon Dieu.~
C'est ici. , À l'origine, le rez - de - chaussée était ThreadLocalRandomOh là là!,Pas démodéjdk7Et plus,AvecjdkLa façon dont.
static {
if (javaVersion() >= 7) {
RANDOM_PROVIDER = new ThreadLocalRandomProvider() {
@Override
@SuppressJava6Requirement(reason = "Usage guarded by java version check")
public Random current() {
return java.util.concurrent.ThreadLocalRandom.current();
}
};
} else {
RANDOM_PROVIDER = new ThreadLocalRandomProvider() {
@Override
public Random current() {
return ThreadLocalRandom.current();
}
};
}
J'ai regardé.nettyEtjdkEn basThreadLocalRandomMode de réalisation,Il y a encore une grande différence, Si vous êtes intéressé, allez voir par vous - même .
J'ai regardé en arrièreThreadLocalInsecureRandomPas encore.publicDécoré,Ce n'est rien.,La classe est finie..
