如何从Dashboard JFrame的TextArea读取数据到main类并执行任务？

解决方案

核心需求实现步骤

  • 从TextArea提取链接数据并按5行分组
  • 启动浏览器打开链接，通过Selenium实现元素等待与点击
  • 在独立线程中执行耗时操作，避免阻塞Swing事件调度线程（EDT）
  • 通过SwingUtilities.invokeLater同步更新表格UI

依赖准备

需要引入Selenium依赖（以Maven为例）：

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.15.0</version>
</dependency>

修改后的Dashboard代码

        SwingUtilities.invokeLater(() -> {
            new Dashboard().setVisible(true);
        });
    }
}

Main类实现 

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

import java.time.Duration;

public class Main {
    public static void handleLink(String url) {
        WebDriver driver = new ChromeDriver();
        try {
            // 1. 打开链接
            driver.get(url);

            // 2. 等待第一个可点击元素并点击（示例选择器，需替换为实际元素选择器）
            WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
            WebElement firstElement = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.first-btn")));
            firstElement.click();

            // 3. 带try-catch的Thread.sleep
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
                System.err.println("睡眠被中断: " + e.getMessage());
            }

            // 4. 等待第二个可点击元素并点击（示例选择器，需替换为实际元素选择器）
            WebElement secondElement = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.second-btn")));
            secondElement.click();

            // 可添加额外操作，如等待页面加载完成
            Thread.sleep(1000);
        } catch (Exception e) {
            System.err.println("处理链接时出错: " + url + ", 错误信息: " + e.getMessage());
        } finally {
            // 关闭浏览器
            driver.quit();
        }
    }
}

关键说明

  1. 线程处理：所有耗时的浏览器操作都放在独立线程中执行，避免阻塞Swing的EDT，防止界面卡顿。
  2. UI更新：通过SwingUtilities.invokeLater确保所有表格UI更新操作在EDT中执行，符合Swing的线程安全要求。
  3. 元素等待：使用Selenium的WebDriverWait结合ExpectedConditions.elementToBeClickable实现可靠的元素等待，比单纯的Thread.sleep更稳定。
  4. 停止控制：通过volatile boolean isRunning变量控制循环执行，实现Stop按钮的终止功能。
