Page directive must not have multiple occurrences of pageencoding

一个jsp文件中不能同时出现两个

pageEncoding

关键词

例如以下的都是错误的:

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1" pageEncoding="GBK"%>

或者这样的:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@page language="java" pageEncoding="UTF-8"%>
