项目目录下配置web.xml

<servlet-name>hello</servlet-name>//设一个servlet的名称

<servlet-class>test.canquick.eniac.demo.ServletDemo</servlet-class>//对应的servlet.clss文件

</servlet>

<servlet-mapping>

<servlet-name>hello</servlet-name>//设置对应配置好的servlet的名称

<url-pattern>/helloServlet</url-pattern>//访问路径

http://localhost:xx端口/helloServlet 就可以访问此servlet

</servlet-mapping>

ServletDemo.java类:

package test.canquick.eniac.demo;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class ServletDemo extends HttpServlet {

public void doGet(HttpServletRequest hsrq,HttpServletResponse hsrs) throws IOException{

hsrs.setCharacterEncoding("UTF-8");

PrintWriter out = hsrs.getWriter();

out.println("<html>");

out.println("<head>");

out.println("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">");

out.println("<title>123456</title>");

out.println("</head>");

out.println("<body><h1>d标s题d</h1></body>");

out.println("</html>");

out.close();

}
