1、不废话，直接代码如下：
teacher.jsp
<%@ 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>教师管理页面</title>
</head>
<body>
<form action="SetDirectory" method="post">
课程资源目录：<input type="text" name="resourceDirectory"><br>
<input type="submit" value="提交">
</form>
<br>
---------------
<form action="SetDirectory" method="post">
作业提交目录：<input type="text" name="homeworkDirectory"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
SetDerictoryServlet.java
@WebServlet("/SetDirectory")
public class SetDirectoryServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public SetDirectoryServlet() {
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.setContentType("text/html;charset=UTF-8");
String resourceDirectory = request.getParameter("resourceDirectory");
String homeworkDirectory = request.getParameter("homeworkDirectory");
System.out.println(resourceDirectory);
System.out.println(homeworkDirectory);
}
2、解决办法：21行加入
if (resourceDirectory!=null) {
resourceDirectory = new String(resourceDirectory.getBytes("ISO8859-1"), "UTF-8");
}
if (homeworkDirectory!=null) {
homeworkDirectory = new String(homeworkDirectory.getBytes("ISO8859-1"), "UTF-8");
}
<input type="text" >发送请求参数，中文乱码问题
