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.
