将JAXB元素编组为SOAP处理转义字符

标签： java soap encoding jaxb saaj

我试图将JAXB元素编组为SOAPBody包装器，我能够对JAXB中的编码字符进行转义，但是当我将其编组为SOAP文档时，它并没有转义这些xml字符。需要任何帮助。 >

我的项目很小，我们没有使用任何外部软件包，而是尝试在开放的jdk中进行此操作。 

         package test;

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

                    SOAPEnvelope soapEnvelope = soapPart.getEnvelope();

                                        throws IOException {
                                    writer.write(ch, start, length);
                                }

jsonObj.forEach(async(data)=>{ try { var result = await collections.collection('studentData').find({rollNumber:parseInt(data.rollNumber)}).toArray() console.log('--------data---------') if (result[0]) { course.push(result[0].course) branch.push(result[0].branch) console.log('-------- entry object ----------') await collections.collection('something').insertOne(something,(err,res)=>{if (err){console.log(err)}else {console.log('inserted')}}) } else { console.log('not inserted') } } catch (e) { console.log(e) } } ) var title = 'Result is out' var body = 'Result of' + reqs.body.company console.log('-------------branch and course--------------') console.log(branch) console.log(course) 和Marshaller.JAXB_ENCODING属性仅在编组到流时有效，而在编组到DOM时无效。如果希望在最终结果中使用CDATA节，最好让JAXB正常封送数据，然后再对DOM进行后处理，将文本节点更改为所需的CDATA节。

您可以使用Apache StringEscapeUtils。由于我不知道您的客户类别是什么样子，因此我仅构建一个简单的示例，请参见下面的类别。结果看起来像这样：

soapMessage.writeTo（System.out）; 

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Header/>
    <SOAP-ENV:Body>&amp;lt;?xml version=&amp;quot;1.0&amp;quot; encoding=&amp;quot;UTF-8&amp;quot; standalone=&amp;quot;yes&amp;quot;?&amp;gt;
            &amp;lt;customer&amp;gt;
            &amp;lt;id&amp;gt;123&amp;amp;lt;&amp;amp;gt;&amp;amp;amp;g&amp;lt;/id&amp;gt;
            &amp;lt;name&amp;gt;Hello&amp;lt;/name&amp;gt;
            &amp;lt;lastname&amp;gt;World*+;:-&amp;amp;lt;&amp;amp;gt;&amp;amp;amp;%$&amp;lt;/lastname&amp;gt;
            &amp;lt;/customer&amp;gt;
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

System.out.println（StringEscapeUtils.unescapeXml（soapBody.getValue（）））; 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <customer>
    <id>123&lt;&gt;&amp;g</id>
    <name>Hello</name>
    <lastname>World*+;:-&lt;&gt;&amp;%$</lastname>
</customer>

好吧，如果没有apache转义工具，那么（丑陋的）解决方法如何。 基本上，您将其编组两次，然后切下所需的部分并将其直接设置在肥皂主体上，请参见下面的示例。

soapMessage.writeTo（System.out）; 

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Header/>
    <SOAP-ENV:Body>&amp;lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&amp;gt;
        &amp;lt;customer&amp;gt;
        &amp;lt;id&amp;gt;Hello &amp;amp;lt;&amp;amp;gt;&amp;amp;amp;g World*+;:-&amp;amp;lt;&amp;amp;gt;&amp;amp;amp;%$&amp;lt;/id&amp;gt;
        &amp;lt;/customer&amp;gt;
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Main.java 

public class Main {
    private static final Logger log = LogManager.getLogger(Main.class);

    public static void main(String[] args) {
        try {
            Customer customer = new Customer().setID("Hello <>&g World*+;:-<>&%$");
            String xml = marshall(new Workaround().setID(marshall(customer)));
            xml = xml.substring(0, xml.indexOf("</id>"));
            xml = xml.substring(xml.indexOf("<id>") + 4);
            System.out.println("\r\n\r\nxml:\r\n" + xml);


            MessageFactory messageFactory = MessageFactory.newInstance();
            SOAPMessage soapMessage = messageFactory.createMessage();
            SOAPPart soapPart = soapMessage.getSOAPPart();
            SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
            SOAPBody soapBody = soapEnvelope.getBody();
            soapBody.setValue(xml);

            System.out.println("\r\n\r\nsoap:");
            soapMessage.writeTo(System.out);
        } catch (Exception e) {
            log.error("no! ", e);
        }

        log.info("stop");
    }

    public static String marshall(Object o) throws Exception {
        System.out.println("-------------------");
        StringWriter sw = new StringWriter();
        JAXBContext jaxbContext = JAXBContext.newInstance(o.getClass());
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        jaxbMarshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
        jaxbMarshaller.marshal(o, System.out);
        jaxbMarshaller.marshal(o, sw);

        return sw.toString();
    }
}

Customer.java 

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="customer")
@XmlAccessorType(XmlAccessType.FIELD)
public class Customer {
    @XmlElement(name="id")
    private String id;

    public String getID() {
        return this.id;
    }

    public Customer setID(String value) {
        this.id = value;
        return this;
    }
}

替代方法.java 

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="workaround")
@XmlAccessorType(XmlAccessType.FIELD)
public class Workaround {
    @XmlElement(name="id")
    private String id;

    public String getID() {
        return this.id;
    }

    public Workaround setID(String value) {
        this.id = value;
        return this;
    }
}
