Error parsing XML. org.xml.sax.SAXParseException: Element type "sqlMapConfig" must be declared出错解决方法

ibatis出现这个错误需要把头部

<!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

改为

<!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
