Javaはjavaxを使用する.mail.JArメールの送信と添付ファイルの送信を許可


Javaはウェブページの开発において绝大な优位を占めているため、ウェブ端のリーダーとして、例えばメールの送信やメールの送信などが必然となり、サイバーセキュリティの再セキュリティはアカウントのセキュリティレベルをもっと高くする必要があります!そのため、これらは開発者にとって身につけなければならないスキルになります!私はずっと开発者として、开発の过程の中でどれだけの难题に出会うことを恐れないで、それを解决する勇気と决心があるかどうか、ここで多く学ぶことが肝心になって、1つのプログラム猿の発展の重要な中の重さになりました!よし、おしゃべりはここまでにして、実際のことをしなさい.
ある開発者がある程度働くと、対象に向かう思考はずっと彼の老子の中で囲まれています!だから私たちはまずメールの定数クラス、実体クラス、ツールクラスなどをカプセル化して、継承するべき継承をします!コードが来た、目を大きく開けて:

メールを送るときに欠かせないメールのタイトルやメールの内容は、メールとして広く使われているものとしてカプセル化されています.では、メールボックスのログインクラスを見てみましょう.

必要な定数クラスが入ってくるはずです
