3 Static Metamodel Generator

	EntityManager em = ...
	CriteriaBuilder criteriaBuilder = em.getCriteriaBuilder();
	
	CriteriaQuery<Employee> criteriaQuery = criteriaBuilder.createQuery(Employee.class);
	Root<Employee> root = criteriaQuery.from(Employee.class);
	root.fetch(Employee_.phoneNumbers, JoinType.LEFT);
	Join<Employee, Department> department = root.join(Employee_.department);
	criteriaQuery.where(criteriaBuilder.equals(department.get(Department_.name), "HR"));
	criteriaQuery.orderBy(criteriaBuilder.asc(root.get(Employee_.id)));
		
	TypedQuery<Employee> query = em.createQuery(criteriaQuery);
	List<Employee> employees = query.getResultList();

To generate static metamodel for managed classes (Entity, MappedSuperclass and Embeddable), add cmobilecom-jpa-processor.jar (which contains an annotation processor) in annotation processor classpath, and pass option -ApersistenceXmlClasspath to the annotation processor.

The following examples for java and android use gradle build.

Java SE/Jakarta EE

configurations {
	processor
}
	
dependencies {
	// annotation processor: generate static metamodel
	processor 'com.cmobilecom:cmobilecom-jpa-processor:2.2.2'
}

// StaticMetamodelGenerator/Enhancer: classpath for loading META-INF/persistence.xml and 
// referenced orm mapping xml files.
def persistenceXmlClasspath = files('src/test/resources').asPath;
	
compileTestJava {
	// annotation processor: generate static metamodel source code which will be
	// added into sourceSet.java.srcDirs
	options.annotationProcessorPath = configurations.processor
	options.compilerArgs << '-ApersistenceXmlClasspath=' + persistenceXmlClasspath
}

Android

configurations {
	processor
}
	
dependencies {
	// annotation processor: generate static metamodel
	processor 'com.cmobilecom:cmobilecom-jpa-processor:2.2.2'
}
	
dependencies {
	// Android does not have javax.annotation that is required to compile generated sources,
	// but it is not needed at runtime.
	compileOnly group: 'javax.annotation', name: 'javax.annotation-api', version: '1.3.2'
	annotationProcessor configurations.processor
}
	
afterEvaluate {
	// StaticMetamodelGenerator/Enhancer: classpath for loading META-INF/persistence.xml and 
	// referenced orm mapping xml files.
	def persistenceXmlClasspath = files('src/androidTest/resources').asPath;

	compileDebugAndroidTestJavaWithJavac {
		options.compilerArgs << '-ApersistenceXmlClasspath=' + persistenceXmlClasspath
	}
}
