小弟我的第一个Servlet
在Web工程下面的src下面新建一个包com.xiao.servlet
再new一个class文件HellWorldServlet.java
内容：
package com.xiao.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorldServlet extends HttpServlet{
@Override
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<html><head><title>Hello World Sample</title></head>");
out.println("<body><h1>Hello World: " + new Date()+ "</h1></body></html>");
System.out.println(new Date());
out.flush();
}
}
再配置web.xml文件：
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>com.xiao.servlet.HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
保存重新启动Tomcat
在浏览器地址栏输入：http://localhost:8080/test/HelloWorld
显示结果和http://localhost:8080/test/HelloWorld.jsp差不多。
