sqlmapclient.queryForList("selectAllStudents",studentList)中返回总是NULL

Question

sqlmapclient = com.ibatis.sqlmap.client.SqlMapClientBuilder.buildSqlMapClient(reader);
if(sqlmapclient!=null){
System.out.println("1226t762");}
reader.close();
public List<Student> queryAllStudent() {
List<Student> studentList = null;
try {
sqlmapclient.queryForList("selectAllStudents",studentList);

if(studentList==null){
System.out.println("12222");}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return studentList;
} 我用PLSQL SELECT *可以得到结果  但是 在IBATIS里面studentList老是返回的是BULL怎么回事啊
