servlet 课堂小测试
1.使用servlet创建一百个连接
2.创建一个表格，基行和偶行颜色不一样
3.添加图片
首先我们
附上java代码：
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.imageio.ImageIO;
public class Yemian extends GenericServlet{
public void service(ServletRequest reques,ServletResponse response)
throws ServletException,IOException{
PrintWriter out = response.getWriter();
out.println("<html><head><title>lianjie</title></head><body>");
for(int i = 0;i<100;i++){
out.println("<table border='4'>");
if(i%2==0){
out.println("<tr><td bgcolor='red'><a href='http://www.baidu.com' target='_blank'>baidu</a></td><td>111</td><td>222</td></tr>");
}else{
out.println("<tr><td bgcolor='blue'><a href='http://www.baidu.com' target='_blank'>baidu</a></td><td>111</td><td>222</td></tr>");
}
out.println("</table>");
}
for(int j = 0;j<10;j++){
out.println("<img src='1.jpg'>");
}
out.println("</body>");
out.println("</html>");
}
}
附上XML代码：
<web-app>
<servlet>
<servlet-name>yemian</servlet-name>
<servlet-class> //此名字要与类名对应
Yemian
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>yemian</servlet-name>
<url-pattern>/hello123</url-pattern> //伪链接
</servlet-mapping>
</web-app>
效果图：
