Jsp和Servlet个人感觉使用起来没有太大区别的，查了一下，说是jsp是Servlet的简化。这说明其本质是一样的，这里简单实现一下jsp和Servlet交互，比较简单，就不多说了，看代码吧。
在src中添加Servlet：
.. code:: java
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;
public class TestServlet extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String strRequest = request.getParameter("test");
if (strRequest != null) {
if ("T".equals(strRequest.trim())) {
request.setAttribute("result11", "你输入的是T，代表正确");
} else if ("F".equals(strRequest.trim())) {
request.setAttribute("result11", "你输入的是F，代表错误");
}
}
//转发
request.getRequestDispatcher("/test.jsp").forward(request, response);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
this.doGet(req, resp);
}
}在WebContent下添加jsp页面test.jsp：
.. code:: html
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
<%
String strResult = (String)request.getAttribute("result11");
if (strResult != null) {
out.println(strResult);
}
%>
<!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=GB18030">
<title>Insert title here</title>
</head>
<body>
<form action="TestServlet">
<input type="text" id="test" name="test">
<input type="submit" value="提交">
</form>
</body>
</html>在WEB-INF下配置web.xml文件：
::
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:javaee="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>TestServlet</servlet-class>
<load-on-startup>5</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/TestServlet</url-pattern>
</servlet-mapping>
</web-app>
