推荐答案

作为单元测试的解决方案：

The solution as a unit test:

public void testURL() throws Exception {
    String strUrl = "http://stackoverflow.com/about";

    try {
        URL url = new URL(strUrl);
        HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
        urlConn.connect();

        assertEquals(HttpURLConnection.HTTP_OK, urlConn.getResponseCode());
    } catch (IOException e) {
        System.err.println("Error creating HTTP connection");
        e.printStackTrace();
        throw e;
    }
}
