私はSpring/hibernateの使用を始めたばかりです。メソッドがクエリ結果に基づいてブール値を返すように、メソッドに次のクエリを記述しました。
public Boolean getStatus(){
logger.debug("Get Emp Status");
Session session = sessionFactory.getCurrentSession();
String hql = "SELECT ec.IsEnable FROM Employee ec WHERE ec.UID=1";
Query query = session.createQuery(hql);
Boolean result = (Boolean) query.uniqueResult();
return result;
}
従業員エンティティ：
@Entity
@Table (name = "FS_Employee")
public class Employee {
@Id
@GeneratedValue
@Column (name = "UID")
private Integer UID;
@Column (name = "IsEnable")
private Boolean IsEnable;
public Employee(){ }
/**
* @return
*/
public Boolean getIsEnable()
{
return IsEnable;
}
/**
* @param boolean1
*/
public void setIsEnable(Boolean boolean1)
{
IsEnable = boolean1;
}
/*
*sets value of UID
*
* @param Integer
*/
public void setUID(Integer UID){
this.UID = UID;
}
/*
*gets value of UID
*
* @param
*/
public Integer getUID(){
return UID ;
}
}

これは機能せず、次のエラーが発生します。
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.QueryException: could not resolve property: IsEnable of: test.spring.model.Employee [SELECT ec.IsEnable FROM test.spring.model.Employee ec WHERE ec.UID=1]

これに関する助けは大歓迎です。
