我尝试使用@ConstructorResult
@SqlResultSetMapping
将本机SQL查询映射到POJO类,如下所示:
@SqlResultSetMapping(
name = "AnomalieMapping",
classes = @ConstructorResult(
targetClass = Anomalie.class,
columns = {
@ColumnResult(name = "anomalieElement", type = String.class),
@ColumnResult(name = "anomalieType", type = String.class),
@ColumnResult(name = "libelle", type = String.class) }))
public class Anomalie {
private ElementAnomalieEnum anomalieElement;
private TypeAnomalieEnum anomalieType;
private String libelle;
public Anomalie() {
super();
}
public Anomalie(final String libelle, final String anomalieElement, final String anomalieType) {
super();
this.libelle = libelle;
this.anomalieElement = ElementAnomalieEnum.valueOf(StringUtils.stripAccents(anomalieElement.toUpperCase()));
this.anomalieType = TypeAnomalieEnum.valueOf(StringUtils.stripAccents(anomalieType.substring(5).toUpperCase()));
}
//Getters and Setters
}
然后在创建本机查询时使用声明的结果集映射,我通过它的名称引用它:
Query query = entityManager.createNativeQuery(sqlQuery, "AnomalieMapping");
return query.getResultList();
但这对我不起作用我收到以下错误:
org.hibernate.MappingException:未知的SqlResultSetMapping [AnomalieMapping]
这是我在SGBD中执行时我的SQL查询生成的内容:
答案 0 :(得分:0)
这就是我解决问题的方法:
我没有声明@SqlResultSetMapping
注释,而是在orm.xml
文件中将其声明为:
<sql-result-set-mapping name="AnomalieMapping">
<constructor-result target-class="xxx.Anomalie">
<column name="libelle"/>
<column name="anomalieElement"/>
<column name="anomalieType"/>
</constructor-result>
</sql-result-set-mapping>
然后在我的DAO中我得到如下结果:
Query query = entityManager.createNativeQuery(sqlQuery, "AnomalieMapping");
return query.getResultList();
