大文字と大文字と小文字の区別デバッグ時の環境変数の名前

Question

デバッグセッションと起動セッションの間に次のような異なる動作が発生する可能性はありますか？

eclipse-debugとmaven-runでは、すべての環境変数を大文字で取得しますが、eclipse-runではWindowsで定義されたものが残ります。

@Test 
public void testEnvironmentVariables() { 
    ArrayList<String> keys = new ArrayList<>(System.getenv().keySet()); 
    Collections.sort(keys); 
    System.out.println(keys); 
}

Answer 1

あなたはJPDAを使用してデバッグされていません。 JPDAを使用すると、Systemで使用されているのとまったく同じHashMapが表示されます。キーの順序が異なるため、2つの異なるVM実行を使用する必要があります。これは100％Javaデバッグではありません。

異なる2つのプロセスでは、環境変数の前にsystem-propertyを使用することで、実行に異なる名前を付けることができます。
