java - 将 JAXB 元素编码为 SOAP 处理转义字符

Question

我正在尝试将 JAXB 元素编码到 SOAPBody 包装器中，我能够转义 JAXB 中的编码字符，但是当我将其编码到 SOAP 文档中时，它不会转义这些 xml 字符。任何帮助。提前致谢。

而且我的项目很小，我们没有使用任何外部包，尝试在开放的 jdk 中执行此操作。

         package test;

        import java.io.File;
        import java.io.IOException;
        import java.io.OutputStreamWriter;
        import java.io.UnsupportedEncodingException;
        import java.io.Writer;

        import javax.xml.bind.JAXBContext;
        import javax.xml.bind.JAXBException;
        import javax.xml.bind.Marshaller;
        import javax.xml.soap.MessageFactory;
        import javax.xml.soap.SOAPBody;
        import javax.xml.soap.SOAPEnvelope;
        import javax.xml.soap.SOAPException;
        import javax.xml.soap.SOAPMessage;
        import javax.xml.soap.SOAPPart;

        import com.sun.xml.internal.bind.marshaller.CharacterEscapeHandler;

        public class JAXBExample {
            public static void main(String[] args) throws SOAPException, IOException {

                Customer customer = new Customer();
                customer.setId(100);
                customer.setName("Hel..<..lo");
                customer.setAge(29);

                try {

                    MessageFactory messageFactory = MessageFactory.newInstance();
                    SOAPMessage soapMessage = messageFactory.createMessage();
                    SOAPPart soapPart = soapMessage.getSOAPPart();
                    SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
                    SOAPBody soapBody = soapEnvelope.getBody();
                    JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
                    Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
                    // jaxbMarshaller.setProperty(CharacterEscapeHandler.class.getName(), new CustomCharacterEscapeHandler());
                    jaxbMarshaller.setProperty("com.sun.xml.internal.bind.characterEscapeHandler",
                            new CharacterEscapeHandler() {
                                public void escape(char[] ch, int start, int length, boolean isAttVal, Writer writer)
                                        throws IOException {
                                    writer.write(ch, start, length);
                                }
                            });


                    // output pretty printed
                    jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
                    jaxbMarshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");

                    jaxbMarshaller.marshal(customer, System.out);
                    jaxbMarshaller.marshal(customer, soapBody);
                    soapMessage.saveChanges();
                    soapMessage.writeTo(System.out);

                }
                catch (JAXBException e) {
                    e.printStackTrace();
                }

            }
        }


 // result just with jaxb ***
    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <customer id="100">
        <payload><![CDATA[Hel..<..lo]]></payload>
        <age>29</age>
        <name>Hel..<..lo</name>
    </customer>
// result jaxb wrapped into SOAPbody***
    <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/>
    <SOAP-ENV:Body>
    <customer id="100">
    <payload>&lt;![CDATA[Hel..&lt;..lo]]&gt;</payload><age>29</age><name>Hel..&lt;..lo</name></customer>
    </SOAP-ENV:Body></SOAP-ENV:Envelope>

我通过使用 jaxbMarshaller 修复了这个问题，如下所示

 jaxbMarshaller.marshal(elem, soapBody);

其中elem是JAXBElement
