JavaFX執行控件監聽的方法時報錯java.lang.IllegalArgumentException: argument type mismatch

Exception in thread “JavaFX Application Thread” java.lang.IllegalArgumentException: argument type mismatch
之所以出現這個錯誤，是因爲我使用了錯誤的監聽時間，由於默認的監聽事件時ActionEvent，然後監聽的是鼠標的事件，應該使用MouseEvent對象纔對。

FXML代碼
onMouseClicked="#showDateTime" 這裏我們監聽的事鼠標點擊。

  <Button fx:id="loginBtn" layoutX="45.0" layoutY="236.0" mnemonicParsing="false" 
  	onMouseClicked="#showDateTime" 
  	prefHeight="26.0" prefWidth="208.0" 
  	styleClass="login-btn" text="芝麻開門" 
  	textFill="WHITE">
	   <cursor>
	       <Cursor fx:constant="HAND" />
	   </cursor>
	   <font>
	       <Font name="System Bold" size="14.0" />
	   </font>
 </Button>

controller代碼
注意：ActionEvent event

public void showDateTime(ActionEvent event){
        System.out.println("登錄按鈕按下，執行相關邏輯");
        Date now = new Date();
        DateFormat df = new SimpleDateFormat("yyyy-dd-MM HH:mm:ss");
        String dateTimeString = df.format(now);
        datetime.setText(dateTimeString);
    }

**解決辦法：只需將方法的入參ActionEvent替換爲MouseEvent即可。

public void showDateTime(MouseEvent event){
        System.out.println("登錄按鈕按下，執行相關邏輯");
        Date now = new Date();
        DateFormat df = new SimpleDateFormat("yyyy-dd-MM HH:mm:ss");
        String dateTimeString = df.format(now);
        datetime.setText(dateTimeString);
    }
