先下载依赖的相关JAR包：http://sourceforge.net/projects/htmlunit/files/
示例1：获取javaeye网站的title

import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

    public static void getHomeTile() throws FailingHttpStatusCodeException, MalformedURLException, IOException{
        final WebClient webClient = new WebClient();
        final HtmlPage htmlPage = webClient.getPage("http://www.javaeye.com");
        System.out.println(htmlPage.getTitleText());
        System.out.println(htmlPage.getTextContent());

    }

可以看见打印出：JavaEye Java编程 Spring框架 AJAX技术 Agile敏捷软件开发 ruby on rails实践 - JavaEye做最棒的软件开发交流社区
和javaeye首页的title属性一样
示例二：获取一个特定的浏览器版本

public void homePage_Firefox() throws Exception {
    final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_2);
    final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net");
    assertEquals("HtmlUnit - Welcome to HtmlUnit", page.getTitleText());
}

示例三：获取特定ID的DIV或者锚链接

public void getElements() throws Exception {
    final WebClient webClient = new WebClient();
    final HtmlPage page = webClient.getPage("http://some_url");
    final HtmlDivision div = page.getHtmlElementById("some_div_id");
    final HtmlAnchor anchor = page.getAnchorByName("anchor_name");
}

实例四：模拟页面提交一个form

public void submittingForm() throws Exception {
    final WebClient webClient = new WebClient();

    // Get the first page
    final HtmlPage page1 = webClient.getPage("http://some_url");

    // Get the form that we are dealing with and within that form,
    // find the submit button and the field that we want to change.
    final HtmlForm form = page1.getFormByName("myform");

    final HtmlSubmitInput button = form.getInputByName("submitbutton");
    final HtmlTextInput textField = form.getInputByName("userid");

    // Change the value of the text field
    textField.setValueAttribute("root");

    // Now submit the form by clicking the button and get back the second page.
    final HtmlPage page2 = button.click();
}
