Spring Jpa Repositories - Orm.xml - jpa

Question

I'm working with Spring Jpa Repositories.
I don't want to define my "named queries" in java classes (entities or repositories). I would like to define my "named queries" in different xml files (like orm.xml).
.... XML FILE ....
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence/orm http://xmlns.jcp.org/xml/ns/persistence/orm_2_1.xsd">
<named-query name="MyEntity.findByField1">
<query>
<![CDATA[
SELECT m
FROM MyEntity m
WHERE
m.field1 = :field1
]]>
</query>
</named-query>
</entity-mappings>
.... REPOSITORY CODE ....
public interface MyEntityRepository extends JpaRepository<MyEntity, String>
{
public Optional<MyEntity> findByField1(#Param("field1") String field1);
}
But my repositories are not finding the xml files with my named queries. How do I configure spring-data-jpa to use these xml files? I do not have a persistence.xml.
Thanks!

Since your MyEntity already has field1 property inside using findByField1 as the Repository method name might be confusing. Change the orm.xml as following and place it inside META-INF/orm.xml
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence/orm http://xmlns.jcp.org/xml/ns/persistence/orm_2_1.xsd">
<named-query name="MyEntity.findByField1OrmXml">
<query>
<![CDATA[
SELECT m
FROM MyEntity m
WHERE
m.field1 = :field1
]]>
</query>
</named-query>
</entity-mappings>
And change the Repository as following
public interface MyEntityRepository extends JpaRepository<MyEntity, String>
{
public Optional<MyEntity> findByField1OrmXml(#Param("field1") String field1);
}
