Page directive: illegal to have multiple occurrences of contentType with different values问题解决

question:

page directive: illegal to have multiple occurrences of contenttype with different values 

(old: text/html; charset=utf-8, new: text/html;charset=utf-8) 

analysis：

出现这个的原因是这两个的contenttype设置不一致所导致的。 

当一个jsp include 另一个jsp时contenttype不一致的时候就会报这个错误。 

案发现场

当前jsp <%@ page contenttype="text/html;charset=utf-8" language="java" %> 

被include的jsp <%@ page contenttype="text/html;charset=utf-8" language="java" %> 

本次报错是因为utf-8和utf-8所导致的。

answer：

把当前的jsp和被引入的jsp的contenttype设置一样就行。 

都改成一样就ok了 

<%@ page contenttype="text/html;charset=utf-8" language="java" %>
