于是我在MYSQL终端执行：
SET character_set_client = GB2312;
SET character_set_connection = GB2312;
SET character_set_database = GB2312;
SET character_set_results = GB2312;
SET character_set_server = GB2312;
SET collation_connection = GB2312_bin;
SET collation_database = GB2312_bin;
SET collation_server = GB2312_bin;
结果还是乱码！
另外，在JSP页面显示中文也是乱码！！
