我正在使用此库:Java EE Maven项目上的https://github.com/bertrandmartel/speed-test-lib
我遇到了以下异常java.lang.ClassNotFoundException: fr.bmartel.speedtest.inter.ISpeedTestListener from [Module "deployment.vp_speedometer_war_exploded.war:main" from Service Module Loader]
我创建了此类:
public class SpeedTest {
public SpeedTest() {
speedTestSocket = new SpeedTestSocket();
}
public void start() {
//set timeout for download
speedTestSocket.setSocketTimeout(SOCKET_TIMEOUT);
// add a listener to wait for speed examples completion and progress
speedTestSocket.addSpeedTestListener(new ISpeedTestListener() {
public void onProgress(final float percent, final SpeedTestReport downloadReport) {
transfertRateBitSecond = downloadReport.getTransferRateBit(); // + " bit/second";
}
});
speedTestSocket.startDownload(SPEED_TEST_SERVER_URI_DL);
}
我的Servlet看起来像:
public class Servlet extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession();
SpeedTest speedTest = new SpeedTest();
speedTest.start();
session.setAttribute("nbr", speedTest.getTransfertRateBitSecond());
response.sendRedirect("index.jsp");
}
}
它在SpeedTest speedTest = new SpeedTest();
处引发了异常
但是我找不到解决方法...

构建项目时,在“ war”中有我的“ jspeedtest-1.13.1.jar”库。没关系

ISpeedTestListener
是interface,您需要实现其所有方法:
speedTestSocket.addSpeedTestListener(new ISpeedTestListener() {
@Override
public void onCompletion(SpeedTestReport report) {
// do nothing
}
@Override
public void onError(SpeedTestError speedTestError, String
errorMessage) {
// do nothing
}
@Override
public void onProgress(float percent, SpeedTestReport report) {
transfertRateBitSecond = downloadReport.getTransferRateBit(); // + " bit/second";
}
});

我觉得问题正在发展。当我尝试访问我的应用程序时,我得到了...
