我想在JSP中创建数组
<?php
$lang = array();
$lang['PAGE_TITLE'] = 'My website page title';
$lang['HEADER_TITLE'] = 'My website header title';
$lang['SITE_NAME'] = 'My Website';
$lang['SLOGAN'] = 'My slogan here';
$lang['HEADING'] = 'My Heading';
echo $lang['SITE_NAME']; // print words "My Website"
?>
我像这样尝试在 JSP 中。
<%
String[] lang;
lang["PAGE_TITLE"] = "My website page title";
lang["HEADER_TITLE"] = "My website header title";
lang["SITE_NAME"] = "My Website";
lang["SLOGAN"] = "My slogan here";
lang["HEADING"] = "My Heading";
out.println(lang["SITE_NAME"]); // print words "My Website"
%>
此错误，无法将 int 转换为字符串帮我谢谢，我想像PHP中的代码数组一样调用数组JSP。
我认为您应该使用与以下内容相同的Map<String,String>：
Map<String, String> lang = new HashMap<String, String>();
lang.put("PAGE_TITLE", "My website page title");
lang.put("HEADER_TITLE","My website header title");
lang.put("SITE_NAME","My Website");
lang.put("SLOGAN", "My slogan here");
lang.put("HEADING","My Heading");
out.println(lang.get("SITE_NAME"));
