我正在尝试部署我的“Hello world!”使用“mvn jetty:run-war”对Jetty进行servlet。 这是我的项目结构:

这是pom.xml:

</build>

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();
    }
}

的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,当我在浏览器中运行“mvn jetty:run-war”并打开“0.0.0.0:8080/hello”时,我得到以下内容:

而不是servlet执行结果(“Hello,World!”)。

我花了几天时间试图弄清楚我做错了什么。你是我最后的希望!

答案 0 :(得分:3)

好吧,最后我找到了解决方案。

实际上我的servlet可以通过以下地址获得:“0.0.0.0:8080/hello/hello”。
