这是我的带有 servlet 类的 java 文件。它以名称 MyServlet.java 保存，类文件也是如此。
这是 xml 文件:
<web-app>
<servlet>
<servlet-name>demoo</servlet-name>
<servlet-class>MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>demoo</servlet-name>
<url-pattern>/demo</url-pattern>
</servlet-mapping>
</web-app>
我已将文件夹设为 WEB-INF，然后是类... WEB-INF 还包含.xml 文件
但是当我尝试运行 servlet 时，它说找不到资源 ps- 我已经在寻找名称为 :demo 的 servlet
localhost:8081/s1/demo* s1 是 war 文件 *
a html file in the war file seems to run fine on the server though.

最佳答案
使用以下代码，删除您的 web.xml，重新编译并部署您的网络应用
import javax.servlet.*;
import java.io.*;
import javax.servlet.annotation.WebServlet;
@WebServlet(name = "MyServlet", urlPatterns = {"/demo"})
public class MyServlet implements Servlet {
public void init(ServletConfig con) {
}
public void service(ServletRequest req, ServletResponse res) throws IOException, ServletException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
String s = "blah";
String s1 = "blah";
out.println("<html><body>");
if ((s.equals(req.getParameter("firstname"))) && (s1.equals(req.getParameter("lastname")))) {
out.println("passwords match");
} else {
out.println("password and name combo does not match");
}
out.println("</body></html>");
}
public void destroy() {
}
public ServletConfig getServletConfig() {
return null;
}
public String getServletInfo() {
return null;
}
}
关于java - 缺少 tomcat 资源，servlet 未运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19469232/
