示例1: processId
import javax.persistence.GeneratedValue; //导入方法依赖的package包/类
private static void processId(
PropertyHolder propertyHolder,
PropertyData inferredData,
SimpleValue idValue,
HashMap<String, IdGenerator> classGenerators,
boolean isIdentifierMapper,
Mappings mappings) {
if ( isIdentifierMapper ) {
throw new AnnotationException(
"@IdClass class should not have @Id nor @EmbeddedId properties: "
+ BinderHelper.getPath( propertyHolder, inferredData )
);
}
XClass returnedClass = inferredData.getClassOrElement();
XProperty property = inferredData.getProperty();
//clone classGenerator and override with local values
HashMap<String, IdGenerator> localGenerators = ( HashMap<String, IdGenerator> ) classGenerators.clone();
localGenerators.putAll( buildLocalGenerators( property, mappings ) );
//manage composite related metadata
//guess if its a component and find id data access (property, field etc)
final boolean isComponent = returnedClass.isAnnotationPresent( Embeddable.class )
|| property.isAnnotationPresent( EmbeddedId.class );
GeneratedValue generatedValue = property.getAnnotation( GeneratedValue.class );
String generatorType = generatedValue != null ?
generatorType( generatedValue.strategy(), mappings ) :
"assigned";
String generatorName = generatedValue != null ?
generatedValue.generator() :
BinderHelper.ANNOTATION_STRING_DEFAULT;
if ( isComponent ) {
generatorType = "assigned";
} //a component must not have any generator
BinderHelper.makeIdGenerator( idValue, generatorType, generatorName, mappings, localGenerators );
if ( LOG.isTraceEnabled() ) {
LOG.tracev( "Bind {0} on {1}", ( isComponent ? "@EmbeddedId" : "@Id" ), inferredData.getPropertyName() );
}
