jxbrowser错误The Chromium profile directory is already used/locked by another BrowserContext instance

一、问题描述

在JAVA FX中使用jxbrowser，第一次打开一个窗口，然后又打开一个窗口就出现如下错误：

代码如下：

BrowserContextParams params = new BrowserContextParams("D:\\IDEA_work\\javafx\\jxbrowser\\cookie"); BrowserContext context = new BrowserContext(params); Browser browser = new Browser(context); BrowserView view = new BrowserView(browser); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(view, BorderLayout.CENTER); frame.setSize(800, 600); frame.setLocationRelativeTo(null); frame.setVisible(true); browser.loadURL("https://www.baidu.com"); CookieStorage cookieStorage = browser.getCookieStorage(); // Create and add new cookie int oneHourInMilliseconds = ; int microsecondsOffset = 1000; // Cookie will be alive during one hour starting from now long expirationTimeInMicroseconds = (System.currentTimeMillis() + oneHourInMilliseconds) * microsecondsOffset; // cookieStorage.setCookie("http://www.baidu.com", "mycookie", "myvalue", // ".baidu.com", "/", expirationTimeInMicroseconds, false, false); List 
  
    cookies = cookieStorage.getAllCookies(); for (Cookie cookie : cookies) { System.out.println("cookie = " + cookie); }

二、解决方法

这是由于浏览器使用相同配置文件目录造成的，也就是上面的BrowserContext，多次初始化时，使用的都是BrowserContext这一个用的是同一个目录。官网提供了一个解决方法：https://jxbrowser.support.teamdev.com/support/solutions/articles/-creating-browser

多个窗口浏览时，初始化Browser时使用不同的目录就行了。
