    @SupportedAnnotationTypes({"jakarta.persistence.Entity","jakarta.persistence.Embeddable","jakarta.persistence.MappedSuperclass"})

public class AnnotationProcessor6
extends AbstractProcessor
    Annotation processing tool generates source code for a meta-model class given the annotated source code of persistent entity.

    This tool is invoked during compilation for JDK6 compiler if

    • OpenJPA and JPA libraries are available in the compiler classpath and
    • Annotation Processor option -Aopenjpa.metamodel=true is specified.

    Usage
    $ javac -classpath path/to/openjpa-all.jar -Aopenjpa.metamodel=true mypackage/MyEntity.java
    will generate source code for canonical meta-model class mypackage.MyEntity_.java. The source code is generated relative to the directory specified in -s option of javac compiler and defaulted to the current directory.

    The Annotation Processor also recognizes the following options (none of them are mandatory):

    -Aopenjpa.log={log level}The logging level. Default is WARN. Permissible values are TRACE, INFO, WARN or ERROR.
    -Aopenjpa.source={n} Java source version of the generated code. Default is 6.
    -Aopenjpa.naming={class name} fully-qualified name of a class implementing org.apache.openjpa.meta.MetaDataFactory that determines the name of a meta-class given the name of the original persistent Java entity class. Defaults to org.apache.openjpa.persistence.PersistenceMetaDataFactory which appends a underscore character (_) to the original Java class name.
    -Aopenjpa.header={url} A url whose content will appear as comment header to the generated file(s). Recognizes special value ASL for Apache Source License header as comment. By default adds a OpenJPA proprietary text.
