为什么Jetty 9.x中的ServletTester如此之慢？

Jetty的ServletTester对于测试Servlet应用程序非常有用.我之前使用过Jetty 6的ServletTester,它运行得很好.

例如:

Jetty 6.x

的pom.xml

  org.mortbay.jetty
  jetty-servlet-tester
  6.1.26
  test

SampleServletTest.java

package example;
import org.junit.Test;
import static org.hamcrest.CoreMatchers.*;
import static org.junit.Assert.*;
import org.mortbay.jetty.testing.HttpTester;
import org.mortbay.jetty.testing.ServletTester;

public class SampleServletTest {

    @Test
    public void testDoGet() throws Exception {
        ServletTester tester = new ServletTester();
        tester.addServlet(SampleServlet.class, "/index");
        tester.start();

        HttpTester request = new HttpTester();
        request.setMethod("GET");
        request.setHeader("Host", "tester"); // should be "tester"
        request.setURI("/index");
        request.setVersion("HTTP/1.1");
        request.setContent("");

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

        assertThat(response.getStatus(), is(equalTo(200)));
    }
}

Jetty 9.x

ServletTester的API在Jetty 9.x中得到了很大改进.

的pom.xml

    org.eclipse.jetty
    jetty-servlet
    9.0.7.v20131107
    test

SampleServletTest.java

package example;
import org.junit.Test;
import static org.hamcrest.CoreMatchers.*;
import static org.junit.Assert.*;
import org.eclipse.jetty.http.HttpTester;
import org.eclipse.jetty.servlet.ServletTester;

public class SampleServletTest {

    @Test
    public void testDoGet() throws Exception {
        ServletTester tester = new ServletTester();
        tester.addServlet(SampleServlet.class, "/index");
        tester.start();

        HttpTester.Request request = HttpTester.newRequest();
        request.setMethod("GET");
        request.setHeader("Host", "tester"); // should be "tester"
        request.setURI("/index");
        request.setVersion("HTTP/1.1");
        request.setContent("");

        HttpTester.Response response = HttpTester.parseResponse(tester.getResponses(request.generate()));

        assertThat(response.getStatus(), is(equalTo(200)));
    }
}

新的API看起来非常酷,但不幸的是上面的代码运行得很慢......这段代码每次运行需要10秒.你相信吗？

有没有人知道这个问题？如果这只是我的错误,这是一个非常好的消息.
