JSP and MySQL connection
######################################################################################################################################################################################################################################################################################################## ################################
Chinese problem:
When JSP and MySQL are connected, you must add:
<% @ Page ContentType = "Text / HTML; Charset = GB2312"%>
If you are the form of your form, you should add:
JDBC: mysql: //127.0.0.1: 3306 / Publish? useunicode = true & characterencoding = GBK "and
<% Request.SetCharacterencoding ("GBK");%>
