org.apache.jasper.JasperException: /commons/meta.jsp(1,1) PWC5988: Page directive: illegal to have multiple occurrences of contentType with different values
(old: text/html; charset=utf-8, new: text/html;charset=UTF-8)

问题：contentType 有多个值

解决：一个页面引入另一个页面时，contentType 应保持一致。

报错是因为一个页面引入另一个页面contentType不一样
