表单提交时，获取输入的中文参数时，浏览器会出现中文乱码，这时在表单响应的jsp文件中加入request.setCharacterEncoding("utf-8");即可解决。相关代码如下：
附：表单提交的jsp文件内容：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>测试JSP内置对象</title>
</head>
<body>
<form action="internalObjResult.jsp" method="post">
uname:<input type="text" name="uname"><br/>
pwd:<input type="password" name="pwd"><br/>
hobbies:<input type="text" name="hobby">
<input type="text" name="hobby"><br/>
submit:<input type="submit" name="submit"/>
</form>
</body>
</html>
表单响应的jsp内容如下：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<body>
<%request.setCharacterEncoding("utf-8");//不加此句，浏览器端中文会显示乱码
String uname=request.getParameter("uname");
out.println(uname+"<br>");
Enumeration<?> e=request.getParameterNames();//不加<?>会有警告
while(e.hasMoreElements()){
out.println(e.nextElement()+"<br>");
}
out.println("所有values:"+"<br>");
String[] s=request.getParameterValues("hobby");
for(String temp:s){
out.println(temp+"<br>");
}
