测试:
String sql = "SELECT NAME as {per.name} from PERSON per";
SQLQuery sqlQuery = session.createSQLQuery(sql);
sqlQuery.addEntity("per", Person.class);
List<Person> persons = sqlQuery.list();
for (Person person : persons) {
System.err.println(person.getName());
}
Person类
@Entity
public class Person {
private Integer pno;
private String name;
private String email;
private Integer age;
private Date birthDate;
private String yourName;
@Transient
public String getYourName() {
return yourName;
}
public void setYourName(String yourName) {
this.yourName = yourName;
}
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public Integer getPno() {
return pno;
