Java2JPA是一个Java类库可以方便的从基本的Java对象来创建JPA映射。
示例代码：
Java2JpaMappingGeneratorjava2JpaMappingGenerator=newJava2JpaMappingGenerator();java2JpaMappingGenerator.setRenderJpaMappingForClassStrategy(newRenderJpaMappingForClassStrategyDefaultImpl());JpaMappingRendererDefaultImpljpaMappingRenderer=newJpaMappingRendererDefaultImpl("target/META-INF/orm.xml");java2JpaMappingGenerator.setJpaMappingRenderer(jpaMappingRenderer);java2JpaMappingGenerator.generateJpaMappingsForPackages("com.test.model");jpaMappingRenderer.createMappedFiles();
