Solve the problem

The original page is included with the contentType inconsistent @page directive contains pages inside, carefully check the first line of the two @page file that contains the page is:

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

Included page:

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

Sure enough, contentType the content inside is not the same, the two files @page contents of the first row of the change to be consistent, then the implementation of the program, run by.

Suggest

Recommended to replace the whole amount in the project: all jsp pages plus @page header content value to be consistent.
