您需要执行javascript：

WebElement span = driver.findElement(By.className("mat-option-text"));
JavascriptExecutor jse = (JavascriptExecutor)driver;
String spanText = jse.executeScript("return arguments[0].childNodes[0].text", span);

文本位于文本节点内。因此，要检索文本，必须为 visibilityOfElementLocated() 您可以使用以下任一定位器策略： cssSelector :

System.out.println(((JavascriptExecutor)driver).executeScript("return arguments[0].firstChild.textContent;", new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("span.mat-option-text")))).toString());
``` `xpath` :

System.out.println(((JavascriptExecutor)driver).executeScript("return arguments[0].firstChild.textContent;", new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//span[@class='mat-option-text']")))).toString());
