SpringのAOPはログ出力を実現し、記録方法の実行時間
17264 ワード
AOPをよりよく理解するために、実践を行い、AOPでログ出力を実現し、方法の実行時間を記録する.プロジェクト全体構造
プロジェクト概要;プロジェクトはSpringBootの簡単なアクセスモジュールを採用しています.このモジュールのログ出力をAOPで実現し,メソッドの実行時間を記録する.

ここではspringbootガイドパッケージを初めて使用する場合は、ネットワーク速度を具体的に見ると長い場合があることに注意してください.
UserControllerテスト用の制御層
ここまでは実は簡単なアクセスモジュールでいいので、SpringBootの便利なところでもあります.
制御レイヤブロック、レコードリクエストの開始、リクエストの終了
サービス層ブロック、メソッド呼び出しの実行時間、パラメータなどを記録する
