新建.jsp文件,charset和pageEncoding默认是ISO-8859-1,这样的话访问页面时会出现乱码,解决办法:将charset和pageEncoding改为UTF-8(或者GBK/GB2312/GB18030,如果想具体了解几种编码的前世今生可参考另一篇文章:网页编码就是那点事).
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"pageEncoding="ISO-8859-1"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body></body></html>

修改后的代码如下:
<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><script type="text/javascript">alert("中文!");</script>中文!</body></html>

总结：修改编码格式为UTF-8
