本文介绍了一个简单的Servlet示例，展示了如何从Servlet接收请求，设置字符编码，并将数据通过setAttribute方法传递给JSP页面。在JSP页面中，通过EL表达式显示了从Servlet传递过来的数据。

servlet——〉jsp

package com.zparkep.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;

@WebServlet("/MyServlet")
public class MyServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;

	public MyServlet() {
		super();
	}

	protected void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		doPost(request, response);
	}

	protected void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		// 设置接收编码格式
		request.setCharacterEncoding("UTF-8");
		// 设置传出编码格式
		response.setCharacterEncoding("UTF-8");



		//重定向
		String user="xiaomimg";
		request.setAttribute("user", user);
	response.sendRedirect("index.jsp");
	
	}
	
}

jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>

${user }
