实际定位的元素位于id为paramFrame1的frame内，因此您需要在查找元素之前切换此frame:-

System.setProperty("webdriver.chrome.driver", "C:\selenium\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://119.81.222.91:8080/camps/security/Login_FS.html");
WebDriverWait wait = new WebDriverWait(driver, 10);
//First switch to frame with id paramFrame1  
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("paramFrame1"));
//Now find the element
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("user"))).sendKeys("xyz");
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("buttonOK"))).click();
