私はSpring RESTコントローラのアドバイスを適用しようとしているので、を@Configurationに、@Aspectのクラスを@ComponentScanに含めました。Spring AOPのアドバイスに引数を渡すと、実行時に例外が発生する
次のコードで作業しています。
@Pointcut("execution(* com.abc.api..controller.*.*(..))")
public static void controllers() {
}
@Before("controllers()")
public void startLogging() {
System.out.println("Here we go.");
}
コントローラメソッドは最初の引数としてHttpSessionを受けています。私はアドバイスでそのセッションを取得したい。だから私は次のことを試みた。
@Pointcut("execution(* com.abc.api..controller.*.*(..))")
public static void controllers() {}
@Pointcut("controllers() && args(session) ")
public static void sessionedController(HttpSession session) {}
@Before("sessionedController(session)")
public void startLogging(HttpSession session) {
System.out.println("Here we are");
}
ただし、起動時にこの例外が発生します。

これはなぜ失敗しているのか、問題の解決方法はわかりません。私もthese docsを調べたが、何も見つけられなかった。
私はそれを解決するために私を案内してください。
