在JUnit测试中运行Jettys ServletTester

Question

我正在尝试在JUnit测试中运行Jettys ServletTester。我首先创建了一个简单的HelloServlet来测试设置，但是当我尝试请求servlet时，我得到一个IllegalAccessException。以下是我到目前为止的情况：

我的单元测试

@Before
public void setUp() throws Exception {
    tester = new ServletTester();
    tester.setContextPath("/context");
    tester.addServlet(HelloServlet.class, "/hello/*");
    tester.start();
}

@After
public void tearDown() throws Exception {
    tester.stop();
}

@Test
public void testDefaultServlet() throws Exception {
    HttpTester request = new HttpTester();
    request.setMethod("GET");
    request.setHeader("Host","127.0.0.1");
    request.setURI("/context/hello/info");
    request.setVersion("HTTP/1.0");

    HttpTester response = new HttpTester();
    response.parse(tester.getResponses(request.generate()));

    assertNull(response.getMethod());
    assertEquals(200,response.getStatus());
    assertEquals("<h1>Hello Servlet</h1>",response.getContent());
}

我的HelloServlet

这个servlet与单元测试在同一个文件中定义，因为我希望它可以用于jetty的初始设置。一切运行后，我会删除它（或者保留它，但它会保留在单元测试中）。

更新这个servlet是在单元测试中定义的，因为它只是作为jetty服务器本身的配置测试。但是jetty无法访问它，并且在将它移动到公共类和文件后，一切都按预期工作。请参阅评论。

class HelloServlet extends HttpServlet {
    @Override
    public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        PrintWriter out = resp.getWriter();
        out.println("Hello, World!");
        out.flush();
    }
}

我的例外......

很奇怪，因为我从http://docs.codehaus.org/display/JETTY/ServletTester几乎直接得到了这个例子。在junit测试中嵌入式jetty servlet容器的任何想法或可能的实例？

您的HelloServlet必须作为公共类实现：

public class HelloServlet extends HttpServlet { ... }
