ani*_*710 8 java spring marshalling jaxb2-maven-plugin spring-boot
我使用jaxb2marshaller将少量元素用CDATA封送到XML时遇到了大麻烦.我已经完成了以下解决方案:
还有更多,但找不到合适的解决方案.他们要么告诉切换到旧的JAXB实现,要么使用MOXY.但是,这不是我的要求.我使用OXM库在下面实现了两个类,并希望生成一个XML,其中很少有元素需要附加CDATA.

Processor handler= new Processor();
handler.setMarshaller(getCastorMarshaller());
handler.setUnmarshaller(getCastorMarshaller());
return handler;
}
@Bean
public Jaxb2Marshaller getCastorMarshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setPackagesToScan("com.pom.dom.whatever.model");
Map<String,Object> map = new HashMap<String,Object>();
map.put("jaxb.formatted.output", true);
jaxb2Marshaller.setMarshallerProperties(map);
return jaxb2Marshaller;
}

在主类:
generateXML(){
public void generateCheckXML(ReportDTO repDTO, String fileName){
AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext();
ctx.register(AppConfig.class);
ctx.refresh();
Processor processor = ctx.getBean(Processor.class);
ObjectFactory objectFactory = new ObjectFactory();
TRIMSInterface trimsInterface = objectFactory.createTRIMSInterface();
// setters
processor.objectToXML(fileName,trimsInterface);
}

和一个带有setter和getter的简单POJO类来生成XML.
我可以在上面的任何地方做一些更改来生成具有所需CDATA属性的XML吗?
注意:我已经尝试过EclipseLink Moxy(@XmlData),但它没有与OXM集成.我希望在我的代码中不使用第三方jar来实现它.
找到了 moxy 集成的解决方案(找不到任何其他方法),如果它可以帮助有需要的人,请在此处发布。
导入 moxy 依赖项并在使用以下行创建 bean 的同一包中添加 jaxb.properties 文件:
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

并 @XmlCDATA在必填字段上添加注释。这生成了带有 CDATA 部分的 xml 文件。
