在使用jaxb2marshaller使用CDATA将少数元素编组到XML时,我遇到了很大的困难。我经历过这样的解决方案:
JAXB Marshalling Unmarshalling with CDATA
How to generate CDATA block using JAXB?
但却找不到合适的解决办法。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库实现了以下两个类,并希望生成一个XML,其中很少有元素需要附加CDATA。
import java.util.HashMap;
import java.util.Map;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
@Configuration
public class AppConfig {
@Bean
public Processor getHandler(){
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;
}
} 和
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.springframework.oxm.Marshaller;
import org.springframework.oxm.Unmarshaller;
public class Processor {
private Marshaller marshaller;
private Unmarshaller unmarshalling;
public void setMarshaller(Marshaller marshaller) {
this.marshaller = marshaller;
}
public void setUnmarshaller(Unmarshaller unmarshalling) {
this.unmarshaller = unmarshaller;
}
//Converts Object to XML file
public void objectToXML(String fileName, Object graph) throws IOException {
FileOutputStream fos = null;
try {
fos = new FileOutputStream(fileName);
marshaller.marshal(graph, new StreamResult(fos));
} finally {
fos.close();
}
}
//Converts XML to Java Object
public Object xmlToObject(String fileName) throws IOException {
FileInputStream fis = null;
try {
fis = new FileInputStream(fileName);
return unmarshaller.unmarshal(new StreamSource(fis));
} finally {
fis.close();
}
}
} 主修班:
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setters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带有所需CDATA属性的XML吗?
注意到:我已经尝试过EclipseLink Moxy(@XmlData),它没有与OXM集成。我希望在代码中不使用第三方jar来实现这一点。

找到了用moxy集成的解决方案(找不到其他方法),如果它帮助了需要帮助的人,就在这里发布。
导入moxy依赖项,并在创建bean的同一个包中添加jaxb.properties文件,并使用以下行:
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory并将@XmlCDATA注释放在所需字段上。这将生成带有CDATA节的xml文件。
