这是主调用
public class TestMain {
public static void main(String[] args) {
StuDao dao=new StudentDaoImpl();
//6.查找student
for (Student student : dao.queryStudent("iFo")) {
System.out.println(student);
}
}
这是所调用的方法：
public List<Student> queryStudent(String stuName) {
List<Student> list=sessionFactory.openSession().selectList("selectStudent",stuName);
return list;
}
这是xml配置
<select id="selectStudent" parameterType="String" resultType="entity.Student">
select * from student where stuName like '%#{stuName}%'
</select>
查询的时候会报

增删改实现着也没啥问题，是不是mybatis相对于ibatis有啥新变动的地方，没有注意到？
------解决方案--------------------
select * from student where stuName like '%#{stuName}%'
这个配置有问题，Mybatis 不能正确换参数。
网上有办法,
改成
select * from student where stuName like CONCAT('%','${stuName}','%' )
或者
select * from student where stuName like '%'||'${stuName}'||'%'
