Question

The content of element type sqlMap must match EMPTY .

初学ibatis，配置Student.xml时，在<sqlMap>一行中出现The content of element type sqlMap must match EMPTY .
代码是：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<sqlMap>

<typeAlias alias="Student" type="com.panda.util.Student"/>

<select id="selectAllStudent" resultClass="Student">
select * from student
</select>

</sqlMap>

Answer 1

从"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">改为

"http://ibatis.apache.org/dtd/sql-map-2.dtd">
