tomcat-servlet 练习一则

先看下目录结构：
(该目录在tomcat/webapps/下面,ch1是项目名)

├───ch1
│   └───WEB-INF
│       │   web.xml
│       │   
│       └───classes
│               Ch1Servlet.class

1.2web.xml

<?xml version="1.0" encoding="utf-8" ?>
<web-app xmlns="http:/java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
	version="2.4">
	
	<servlet>
		<servlet-name>Chapter1 Servlet</servlet-name>
		<servlet-class>Ch1Servlet</servlet-class>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>Chapter1 Servlet</servlet-name>
		<url-pattern>/time</url-pattern>
	</servlet-mapping>
</web-app>

2.3 Ch1Servlet.java

(Ch1Servlet.class 是由Ch1Servlet.java 编译而来的)
(编译命令：javac -class d: omcatlibServlet-api.jar -d classes src/Ch1Servlet.java)
(这条命令会在当前目录classes文件夹下生成Ch1Servlet.class)

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class Ch1Servlet extends HttpServlet {
	public void doGet(HttpServletRequest reque, HttpServletResponse response) throws IOException {
		PrintWriter out = response.getWriter();
		java.util.Date today = new java.util.Date();
		out.println("<html>" +
			"<body>" +
			"<h1 align=center>HF's chapter1</h1>" +
			"<br>" + today + "</body></html>");
	}
}

2.4 启动并访问 localhost:8088/ch1/time

端口是你tomat配置文件中设置的。
ch1 是你在tomcat/webapps中创建的项目文件夹名。
time 是你在web.xml中指定的访问路径。

有了计划记得推动，不要原地踏步。
