如果我要查找的元素没有唯一的id，那我肯定要查找一堆元素出来，譬如用findElements(By.className)，这个时候的话要显式等待应该怎么办？还是用“presenceOfElementLocated()” 吗？

public class BasePage {

    public WebDriver driver;

    public BasePage() {
    }

    public BasePage(WebDriver driver) {
        this.driver = driver;
    }

    public WebElement getElement(String key) {
        return new WebDriverWait(driver, 5)
                .until(ExpectedConditions.presenceOfElementLocated(this.getByLocal(key)));
//        return driver.findElement(this.getByLocal(key));
    }

// 老师请看这里！！！
    public List<WebElement> getElements(String key){
        return (List<WebElement>) new WebDriverWait(driver, 5)
                .until(ExpectedConditions.presenceOfElementLocated(this.getByLocal(key)));
//        return driver.findElements(this.getByLocal(key));
    }

    public By getByLocal(String key) {
        String locator = HandlePropertiesFile.getValues(key);
        String locateBy = locator.split(">")[0];
        String locateValue = locator.split(">")[1];
        if (locateBy.equals("id")) {
            return By.id(locateValue);
        } else if (locateBy.equals("name")) {
            return By.name(locateValue);
        } else if (locateBy.equals("className")) {
            return By.className(locateValue);
        } else if (locateBy.equals("xpath")) {
            return By.xpath(locateValue);
        } else if (locateBy.equals("tagName")) {
            return By.tagName(locateValue);
        } else if (locateBy.equals("linkText")) {
            return By.linkText(locateValue);
        } else if (locateBy.equals("cssSelector")) {
            return By.cssSelector(locateValue);
        } else {
            return null;
        }
    }

}
