The ToString () method must be added to the entity.

@Override
Public String toString () {
Return "Student [stu_id=" + stu_id + ", stu_name=" + stu_name
+ ", stu_age=" + Stu_age + ", stu_sex=" + Stu_sex + "]";
}

The ToString () method is automatically generated in the entity before the specific data can be put into the datamap.
