实现步骤：
（1）创建servlet browserserver
（2）调用httpservletrequest对象的getservername()方法获取服务器名称
（3）调用httpservletrequest对象的getserverport()方法获取服务器端口
（4）首先调用getservletcontext()方法获取servletcontext对象，然后调用servletcontext对象的getserverinfo()方法获取服务器环境信息名称、版本信息
（5）利用httpservletresponse对象的printwriter将信息显示到页面
package example.servlet;
import java.io.ioexception;
import java.io.printwriter;
import javax.servlet.servletcontext;
import javax.servlet.servletexception;
import javax.servlet.annotation.webservlet;
import javax.servlet.http.httpservlet;
import javax.servlet.http.httpservletrequest;
import javax.servlet.http.httpservletresponse;
/**
* servlet implementation class browserserver
*/
@webservlet("/browserserver")
public class browserserver extends httpservlet {
private static final long serialversionuid = 1l;
protected void processrequest(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
response.setcontenttype("text/html;charset=utf-8");
printwriter out=response.getwriter();
servletcontext context=getservletcontext();
out.println("<html>");
out.println("<head>");
out.println("<title>服务器信息</title>");
out.println("</head>");
out.println("<body>");
out.println("<h3>服务器名称："+request.getservername()+"</h3>");
out.println("<h3>服务器端口："+request.getserverport()+"</h3>");
out.println("<h3>"+context.getserverinfo()+"</h3>");
out.println("</body>");
out.println("<html>");
out.close();
}
protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
processrequest(request,response);
}
protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
processrequest(request,response);
}
}
