在使用 jaxb2marshaller 使用 CDATA 将几个元素编组为 XML 时,我遇到了很大的麻烦。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。我已经使用 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();
}
}
}
在主类中:
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);
}
}
以及一个带有 setter 和 getter 的简单 POJO 类来生成 XML。
我可以在上面的任何地方进行一些更改以生成具有所需 CDATA 属性的 XML 吗?
注意:我已经尝试过 EclipseLink Moxy(@XmlData),它没有与 OXM 集成。我希望在我的代码中不使用第三方 jar 来实现这一点。
