jsp调用servlet的方法：首先在js里面写一个调用servlet的事件；然后利用“”标签的“onload”调用这个事件，来实现jsp页面调用servlett即可。
本篇文章使用方法：先在js里面写一个调用servlet的事件（可以利用ajax），然后利用<body>标签的onload调用这个事件。
来进行jsp页面调用servlet的目的。
推荐课程：java教程。
代码如下：
jsp文件代码如下：
<%@ page language="java" contenttype="text/html; charset=utf-8" pageencoding="utf-8"%><!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd"><html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"><title>insert title here</title> <script type="text/javascript" src="http://www.daimajiayuan.com/download/jquery/jquery-1.10.2.min.js"></script> <script type="text/javascript" src="http://cdn.bootcss.com/bootstrap-select/2.0.0-beta1/js/bootstrap-select.js"></script> <link rel="stylesheet" type="text/css" href="http://cdn.bootcss.com/bootstrap-select/2.0.0-beta1/css/bootstrap-select.css"> <!-- 3.0 --> <link href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"> <script src="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script> <!-- 2.3.2 <link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"> <script src="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.js"></script> --> <script type="text/javascript"> function a(){ $.ajax({ url:loaddataservlet,//servlet文件的名称 type:get, success:function(e){ alert(servlet调用成功！); } }); } </script> </head><body onload="a()"></body></html>
servlet文件代码如下：
package com.servlet;import java.io.ioexception;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 loaddataservlet */@webservlet(urlpatterns = /loaddataservlet,loadonstartup = 1)public class loaddataservlet extends httpservlet { private static final long serialversionuid = 1l; /** * @see httpservlet#httpservlet() */ public loaddataservlet() { super(); // todo auto-generated constructor stub } /** * @see httpservlet#doget(httpservletrequest request, httpservletresponse response) */ protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception { // todo auto-generated method stub response.getwriter().append(served at: ).append(request.getcontextpath()); } /** * @see httpservlet#dopost(httpservletrequest request, httpservletresponse response) */ protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception { // todo auto-generated method stub doget(request, response); }}
