OXM绝对适合您!
Jaxb2Marshaller的简单Java配置如下所示:
//...import java.util.HashMap;import org.springframework.oxm.jaxb.Jaxb2Marshaller;//...@Configurationpublic class MyConfigClass { @Bean public Jaxb2Marshaller jaxb2Marshaller() { Jaxb2Marshaller marshaller = new Jaxb2Marshaller(); marshaller.setClassesToBeBound(new Class[]{//all the classes the context needs to know aboutorg.kaushik.xsds.All.class,org.kaushik.xsds.Of.class,org.kaushik.xsds.Your.class,org.kaushik.xsds.Classes.class }); // "alternative/additiona - ly": // marshaller.setContextPath(<jaxb.context-file>) // marshaller.setPackagesToScan({"com.foo", "com.baz", "com.bar"}); marshaller.setMarshallerProperties(new HashMap<String, Object>() {{ put(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, true); // set more properties here... }}); return marshaller; }}
在您的Application / Service类中,您可以采用以下方式:
import java.io.InputStream;import java.io.StringWriter;import javax.xml.bind.JAXBException;import javax.xml.transform.Result;import javax.xml.transform.stream.StreamResult;import javax.xml.transform.stream.StreamSource;import org.springframework.oxm.jaxb.Jaxb2Marshaller;@Componentpublic class MyMarshallerWrapper { // you would rather: @Autowired private Jaxb2Marshaller marshaller; // than: // JAXBContext jc = JAXBContext.newInstance(User.class); // Marshaller marshaller = jc.createMarshaller(); // marshalls one object (of your bound classes) into a String. public <T> String marshallXml(final T obj) throws JAXBException { StringWriter sw = new StringWriter(); Result result = new StreamResult(sw); marshaller.marshal(obj, result); return sw.toString(); } // (tries to) unmarshall(s) an InputStream to the desired object. @SuppressWarnings("unchecked") public <T> T unmarshallXml(final InputStream xml) throws JAXBException { return (T) marshaller.unmarshal(new StreamSource(xml)); }}
