我已经使用 Apache CXF wsdl2java 工具生成了 Web 服务客户端。它工作正常，但在一种方法中，我必须发送包含特殊字符的字符串。生成的客户端使用转义字符。我不要那个。我想将字符串放在 "<[!CDATA[ ]]>" 块中。我可以在代码中手动添加“<[!CDATA[]]>”——这不会是一个问题，但我不知道如何关闭 cachracter 转义。有没有人有这样的问题？如何以最简单的方式解决它？

[编辑]：丹尼尔库尔普回答后，我这样做了：

我写了拦截器：

public class CDATAInterceptor extends AbstractPhaseInterceptor<Message> {

    public CDATAInterceptor(String phase) {
        super(phase);
    }

    public void handleMessage(Message message) {
        XMLStreamWriter writer = (XMLStreamWriter) message.getContent(XMLStreamWriter.class);
        if (writer != null && !(writer instanceof MyXmlWriter)) {
            message.setContent(XMLStreamWriter.class, new MyXmlWriter(writer));
        }
    }
}

我已将它添加到任何可能的阶段（以防万一 - 我可能应该放入 MARSHAL 或 PRE_MARSHAL）。这是我如何添加拦截器的代码：

MyService service = new MyService(new URL(http://my_url_adress?wsdl));
proxy = service.getMyServiceSoap12();
Client client = ClientProxy.getClient(proxy);

client.getOutInterceptors().add(new CDATAInterceptor(Phase.INVOKE));
client.getOutInterceptors().add(new CDATAInterceptor(Phase.MARSHAL));
client.getOutInterceptors().add(new CDATAInterceptor(Phase.MARSHAL_ENDING));
client.getOutInterceptors().add(new CDATAInterceptor(Phase.POST_INVOKE));
client.getOutInterceptors().add(new CDATAInterceptor(Phase.POST_LOGICAL));
client.getOutInterceptors().add(new CDATAInterceptor(Phase.POST_LOGICAL_ENDING));
...

这是 MyXmlWriter 类代码：

public class MyXmlWriter implements XMLStreamWriter {

    protected XMLStreamWriter originalXmlWriter;

    public MyXmlWriter(XMLStreamWriter originalXmlWriter) {
        this.originalXmlWriter = originalXmlWriter;
    }

    public void writeStartElement(String localName) throws XMLStreamException {
        this.originalXmlWriter.writeStartElement(localName);
    }

    public void writeStartElement(String namespaceURI, String localName) throws XMLStreamException {
        this.originalXmlWriter.writeStartElement(namespaceURI, localName);
    }

    public void writeStartElement(String prefix, String localName, String namespaceURI) throws XMLStreamException {
        this.originalXmlWriter.writeStartElement(prefix, localName, namespaceURI);
    }

    public void writeEmptyElement(String namespaceURI, String localName) throws XMLStreamException {
        this.originalXmlWriter.writeEmptyElement(namespaceURI, localName);
    }

    public void writeEmptyElement(String prefix, String localName, String namespaceURI) throws XMLStreamException {
        this.originalXmlWriter.writeEmptyElement(prefix, localName, namespaceURI);
    }

    public void writeEmptyElement(String localName) throws XMLStreamException {
        this.originalXmlWriter.writeEmptyElement(localName);
    }

    public void writeEndElement() throws XMLStreamException {
        this.originalXmlWriter.writeEndElement();
    }

    public void writeEndDocument() throws XMLStreamException {
        this.originalXmlWriter.writeEndDocument();
    }

    public void close() throws XMLStreamException {
        this.originalXmlWriter.close();
    }

    public void flush() throws XMLStreamException {
        this.originalXmlWriter.flush();
    }

    public void writeAttribute(String localName, String value) throws XMLStreamException {
        this.originalXmlWriter.writeAttribute(localName, value);
    }

    public void writeAttribute(String prefix, String namespaceURI, String localName, String value) throws XMLStreamException {
        this.originalXmlWriter.writeAttribute(prefix, namespaceURI, localName, value);
    }

    public void writeAttribute(String namespaceURI, String localName, String value) throws XMLStreamException {
        this.originalXmlWriter.writeAttribute(namespaceURI, localName, value);
    }

    public void writeNamespace(String prefix, String namespaceURI) throws XMLStreamException {
        this.originalXmlWriter.writeNamespace(prefix, namespaceURI);
    }

    public void writeDefaultNamespace(String namespaceURI) throws XMLStreamException {
        this.originalXmlWriter.writeDefaultNamespace(namespaceURI);
    }

    public void writeComment(String data) throws XMLStreamException {
        this.originalXmlWriter.writeComment(data);
    }

    public void writeProcessingInstruction(String target) throws XMLStreamException {
        this.originalXmlWriter.writeProcessingInstruction(target);
    }

    public void writeProcessingInstruction(String target, String data) throws XMLStreamException {
        this.originalXmlWriter.writeProcessingInstruction(target, data);
    }

    public void writeCData(String data) throws XMLStreamException {
        this.originalXmlWriter.writeCData(data);
    }

    public void writeDTD(String dtd) throws XMLStreamException {
        this.originalXmlWriter.writeDTD(dtd);
    }

    public void writeEntityRef(String name) throws XMLStreamException {
        this.originalXmlWriter.writeEntityRef(name);
    }

    public void writeStartDocument() throws XMLStreamException {
        this.originalXmlWriter.writeStartDocument();
    }

    public void writeStartDocument(String version) throws XMLStreamException {
        this.originalXmlWriter.writeStartDocument(version);
    }

    public void writeStartDocument(String encoding, String version) throws XMLStreamException {
        this.originalXmlWriter.writeStartDocument(encoding, version);
    }

    public void writeCharacters(String text) throws XMLStreamException {
        this.originalXmlWriter.writeCData(text);
    }

    public void writeCharacters(char[] text, int start, int len) throws XMLStreamException {
        this.originalXmlWriter.writeCData(String.copyValueOf(text, len, len));
    }

    public String getPrefix(String uri) throws XMLStreamException {
        return this.originalXmlWriter.getPrefix(uri);
    }

    public void setPrefix(String prefix, String uri) throws XMLStreamException {
        this.originalXmlWriter.setPrefix(prefix, uri);
    }

    public void setDefaultNamespace(String uri) throws XMLStreamException {
        this.originalXmlWriter.setDefaultNamespace(uri);
    }

    public void setNamespaceContext(NamespaceContext context) throws XMLStreamException {
        this.originalXmlWriter.setNamespaceContext(context);
    }

    public NamespaceContext getNamespaceContext() {
        return this.originalXmlWriter.getNamespaceContext();
    }

    public Object getProperty(String name) throws IllegalArgumentException {
        return this.originalXmlWriter.getProperty(name);
    }
}

这不起作用。我一直在调试以检查它是如何工作的，我注意到 MyXmlWriter.writeCharacters(...) 方法几乎从未使用过。输出消息仍然有转义字符，而不是在 CDATA 中。

[Edit2]：我刚刚发现我必须添加行：

message.put("disable.outputstream.optimization", Boolean.TRUE);

唯一的方法是编写一个拦截器，从消息中获取 XMLStreamWriter，用一个新的 XMLStreamWriter 包装它，该 XMLStreamWriter 将覆盖字符方法并调用委托 cdata 方法而不是字符。
