<%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8"%>
<%
Locale locale = request.getLocale();

Calendar calendar = Calendar.getInstance(locale);

int hour = calendar.get(Calendar.HOUR_OF_DAY);

String greeting = "";

if (hour <= 6) {
    greeting = "凌晨好，您该睡觉了。良好的睡眠是美好一天的开始。";
} else if (hour <= 9) {
    greeting = "早上好。早餐应该注意营养。";
} else if (hour <= 12) {
    greeting = "上午好。工作时注意保护眼睛。";
} else if (hour <= 18) {
    greeting = "下午好。小心工作中打瞌睡。";
} else if (hour <= 24) {
    greeting = "晚上好。放松一下自己，好好休息。睡觉不要太晚啊~~";
} else {

}

欢迎页面











<%= greeting %>

jsp的页面在Eclipse下写的，启动tomcat，然后用Eclipse的浏览器访问（http://localhost:8080/jsp/greeting.jsp）

报错
type Exception report
message /greeting.jsp (line: 2, column: 9) quote symbol expected
