我正在嘗試讓一個簡單的嵌入式 tomcat10.1.0-M11示例正常作業，但是localhost refused to connect當我轉到http://localhost:8080/aa. 還沒有 StackOverflow 標簽embedded-tomcat-10。
這是我的代碼：
import jakarta.servlet.ServletException;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import org.apache.catalina.Context;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.startup.Tomcat;
public class App {
public static void main(String[] args) throws LifecycleException {
Tomcat tomcat = new Tomcat();
tomcat.setBaseDir("temp");
tomcat.setPort(8080);
String contextPath = "";
String docBase = new File(".").getAbsolutePath();
Context context = tomcat.addContext(contextPath, docBase);
class SampleServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
PrintWriter writer = resp.getWriter();
writer.println("<html><title>Welcome</title><body>");
writer.println("<h1>Have a Great Day!</h1>");
writer.println("</body></html>");
}
}
String servletName = "SampleServlet";
String urlPattern = "/aa";
tomcat.addServlet(contextPath, servletName, new SampleServlet());
context.addServletMappingDecoded(urlPattern, servletName);
tomcat.start();
tomcat.getServer().await();
}
}

更新
我瀏覽了每一個版本，我發現這個錯誤是在版本中引入的，9.0.0.M4從那以后就再也沒有解決過。任何較新的版本都會使這個示例變得無用。
uj5u.com熱心網友回復：
我添加了 2 個解決方案，您可以選擇任何人，因此您的最終主要功能將如下所示：
public static void main(String[] args) throws LifecycleException {
Tomcat tomcat = new Tomcat();
tomcat.setBaseDir("temp");
// Solution 1
//tomcat.setPort(8080);
//tomcat.getConnector();
// Solution 2, make server listen on 2 ports
Connector connector1 = tomcat.getConnector();
connector1.setPort(8080);
Connector connector2 = new Connector();
connector2.setPort(8090);
String contextPath = "";
String docBase = new File(".").getAbsolutePath();
Context context = tomcat.addContext(contextPath, docBase);
class SampleServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
PrintWriter writer = resp.getWriter();
writer.println("<html><title>Welcome</title><body>");
writer.println("<h1>Have a Great Day!</h1>");
writer.println("</body></html>");
}
}
String servletName = "SampleServlet";
String urlPattern = "/aa";
tomcat.addServlet(contextPath, servletName, new SampleServlet());
context.addServletMappingDecoded(urlPattern, servletName);
tomcat.start();
tomcat.getService().addConnector(connector1);
tomcat.getService().addConnector(connector2);
tomcat.getServer().await();
}
uj5u.com熱心網友回復：
如this question中所述，您需要添加一個連接器，可以這樣完成：
...
tomcat.setPort(8080);
tomcat.getConnector();
...
