我正在尝试使用“mvn jetty： run-war”将我的“Hello world！”servlet部署到Jetty。这是我的项目结构：
这是pom. xml：

App.java：
package com.ekropotin.test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.*;
public class App implements Servlet {
private ServletConfig config;
public void init(ServletConfig config) throws ServletException {
this.config = config;
}
public void destroy() {
}
public ServletConfig getServletConfig() {
return config;
}
public String getServletInfo() {
return "A Simple Servltet";
}
public void service(ServletRequest request, ServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html><head>");
out.println("<title>A Sample Servlet!</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello, World!</h1>");
out.println("</body></html>");
out.close();
}
}
web. xml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>com.ekropotin.test.App</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
</web-app>
问题是，当我运行“mvn jetty： run-war”并在浏览器中打开“0.0.0.0:8080/hello”时，我得到以下内容：
而不是servlet执行结果（“Hello， World！”）。
我已经花了好几天时间想弄清楚我做错了什么。你们是我最后的希望了！
好吧，我终于找到了解决办法。
实际上，我的servlet可以通过以下地址获得：“0.0.0.0:8080/hello/hello”。
