JPA Query Entity not mapped error
提问by mt.uulu
Testing is not passing in the following code. Debugging shows the error is in the creation of the query.
测试未通过以下代码。调试显示错误在于查询的创建。
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Catalog is not mapped [SELECT c FROM Catalog c WHERE c.name = :name]
at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1347)
at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1288)
Entity class:
实体类：
@Entity
@Table(name = "eb_catalog", uniqueConstraints=@UniqueConstraint(columnNames="name"))
public class Catalog implements ICatalog, Serializable {
and the query itself:
和查询本身：
TypedQuery<Catalog> query = em.createQuery(
"SELECT c FROM Catalog c WHERE c.name = :name", Catalog.class)
.setParameter("name", catName);
CTRL + click on Catalog is opening the entity, so the name matches the entity in the query.
CTRL + 单击 Catalog 正在打开实体，因此名称与查询中的实体相匹配。
thanks in advance.
提前致谢。

You may have forgotten to map your entity class in the persistence.xml.
Take a look :)
您可能忘记在persistence.xml. 看一看 ：）
