最近在学习servlet。刚开始时，按照案例一行一行的敲代码。不过，出问题了。
hello1.html
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="UTF-8"> 5 </head> 6 <body style="font-size:24px"> 7 <form action="hello1" method="get"> 8 Name:<input name="name"><br /> 9 Content Me:<br /> 10 QQ<input type="checkbox" name="contact" value="qq" /> 11 Tel<input type="checkbox" name="contact" value="tel" /> 12 WeChat<input type="checkbox" name="contact" value="wechat" /> 13 <br /> 14 <input type="submit" value="OK" /> 15 </form> 16 </body> 17 </html>
web.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://xmlns.jcp.org/xml/ns/javaee" 4 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 5 http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 6 id="WebApp_ID" version="3.1"> 7 <servlet> 8 <servlet-name>hello1Servlet</servlet-name> 9 <servlet-class>unitTwo.Hello1Servlet</servlet-class> 10 </servlet> 11 <servlet-mapping> 12 <servlet-name>hello1Servlet</servlet-name> 13 <url-pattern>/hello1</url-pattern> 14 </servlet-mapping> 15 </web-app>
Hello1Servlet.java
1 package unitTwo; 2 3 import java.io.IOException; 4 import java.io.PrintWriter; 5 6 import javax.servlet.ServletException; 7 import javax.servlet.http.HttpServlet; 8 import javax.servlet.http.HttpServletRequest; 9 import javax.servlet.http.HttpServletResponse; 10 11 public class Hello1Servlet extends HttpServlet { 12 /** 13 * 14 */ 15 private static final long serialVersionUID = 1L; 16 17 protected void service(HttpServletRequest request, HttpServletResponse response) 18 throws ServletException, IOException { 19 PrintWriter out = response.getWriter(); 20 String name = request.getParameter("name"); 21 out.println("<h1>Hello, " + name + "</h1>"); 22 String[] contacts = request.getParameterValues("contact"); 23 if (contacts != null) { 24 out.print("<h1>Contact Information: </h1>"); 25 for (String info : contacts) { 26 out.print("<h1>" + info + "</h1>"); 27 } 28 } 29 out.close(); 30 } 31 }
运行在TOMCAT v8.0上，结果是，在Eclipse EE上运行时，正常显示，但是到了浏览器上，就出问题了，显示为未找到该网页，应该是错误404。
至于原因，首先归结于在Eclipse EE上服务开启受到了限制，然后关了Eclipse EE，用命令重启服务，结果还是错误。
纠结了一天了，决定先将问题写下来，待深入些再来解决。
或者希望有大神能降临，轻轻松松的将这个问题秒杀。
