java - 正则表达式

Question

我有一些代码:

String url1 = "http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/cart.workflow:ShowCart?shopping-menu-s...";
String url2 = "shop.lenovo.com/(.*)/en_US/cart";

Pattern p = Pattern.compile(url2);
Matcher m = p.matcher(url1);

但是 m.matches() 对我来说返回 false。为什么？

Answer 1

请尝试这个而不是您的代码

    String url1 = "http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/cart.workflow:ShowCart?shopping-menu-s...";

    String subS1 = "shop.lenovo.com/";
    Pattern p1 = Pattern.compile(subS1);
    Matcher match1 = p1.matcher(url1);

    String subS2 = "en_US/cart";
    Pattern p2 = Pattern.compile(subS2);
    Matcher match2 = p2.matcher(url1);

    if (match1.find() && match2.find())
    {
        // Whatever you like
    }
