Using a Jetty Server with JUnit tests
提问by stevebot
I've been trying to test my web app by starting a Jetty server in the BeforeClass method of my JUnit test case and then using a HttpClient to form request to the server. I get the server to start without any issues, but I keep getting 404's when I try to make a request.
我一直在尝试通过在 JUnit 测试用例的 BeforeClass 方法中启动 Jetty 服务器，然后使用 HttpClient 向服务器发送请求来测试我的 Web 应用程序。我让服务器毫无问题地启动，但是当我尝试发出请求时，我一直收到 404。
The configuration of my server is like the following:
我的服务器配置如下：
public void start() throws Exception {
if (server == null) {
server = new Server(PORT);
server.setStopAtShutdown(true);
wac = new WebAppContext();
wac.setContextPath("/app");
wac.setResourceBase("war");
wac.setClassLoader(this.getClass().getClassLoader());
server.addHandler(wac);
server.start();
}
}
Is there something wrong with my config? The server is running, and I can see that I am hitting it, it just can't find any resources.
我的配置有问题吗？服务器正在运行，我可以看到我正在击中它，它只是找不到任何资源。

You probably need to define this servlet as a resource in your deployment descriptor (web.xml or jetty-web.xml). Just a guess; a 404 indicates that your code isn't running at all, and therefore isn't the problem. The problem is occurring before your code even has a chance to execute.
您可能需要将此 servlet 定义为部署描述符（web.xml 或 jetty-web.xml）中的资源。只是一个猜测；404 表示您的代码根本没有运行，因此不是问题。问题发生在您的代码甚至有机会执行之前。

This is a complete Junit test class that uses jetty:
这是一个使用 jetty 的完整 Junit 测试类：
package test.server;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.webapp.WebAppContext;
public class MockPortalTest {
private Server server;
@Before
public void startServer() throws Exception {
server = new Server(8080);
server.setStopAtShutdown(true);
WebAppContext webAppContext = new WebAppContext();
webAppContext.setContextPath("/app");
webAppContext.setResourceBase("src/main/webapp");
webAppContext.setClassLoader(getClass().getClassLoader());
server.addHandler(webAppContext);
server.start();
}
@Test
public void shouldBePreAuthenticated() throws Exception {
String userId = "invalid";
HttpClient client = new DefaultHttpClient();
HttpGet mockRequest = new HttpGet("http://localhost:8080/app");
mockRequest.setHeader("http-user",userId);
HttpResponse mockResponse = client.execute(mockRequest);
BufferedReader rd = new BufferedReader
(new InputStreamReader(mockResponse.getEntity().getContent()));
// DO YOUR ASSERTIONS
}
@After
public void shutdownServer() throws Exception {
server.stop();
}
}

I started with the code snippet in the first post and then started to fight my way through. The code below finally worked for me:
我从第一篇文章中的代码片段开始，然后开始努力完成。下面的代码终于对我有用：
Server server = new Server(8080);
server.setStopAtShutdown(true);
WebAppContext webAppContext = new WebAppContext();
webAppContext.setContextPath("/app");
webAppContext.setResourceBase("src/main/webapp");
webAppContext.setClassLoader(getClass().getClassLoader());
server.addHandler(webAppContext);
server.start();
URL url = new URL("http://localhost:8080/app/some_call");
URLConnection connection = url.openConnection();
List<String> lines = IOUtils.readLines(connection.getInputStream());
System.out.println(lines.get(0));
POM looks like this:
POM 看起来像这样：
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty</artifactId>
<version>${jetty.version}</version>
</dependency>
<dependency>

<artifactId>jetty-util</artifactId>

<jetty.version>6.1.25</jetty.version>

I think you forgot to set:
我想你忘了设置：
wac.setWar("/path/to/war/file");
Or better, use the constructor:
或者更好的是，使用构造函数：
wac = new WebAppContext("/path/to/war/file", "/app");
