Question

我正在尝试发送一条包含另一个XML的CDATA部分的soap消息，但是我收到了解析错误。我需要将XML数据嵌入CDATA部分。

这是我下面的代码;

import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
import org.apache.axis.AxisFault;

import com.levo.rec.*;

public class REC
{
    public static void main(String args[])
    {
        String mesaj = 
        "<![CDATA[                                                                         " + 
        "   <REC_DATA xmlns=\"http://www.levo.com/REC\">                                   " + 
        "   <RECheader RECID=\"\" REClabel=\"\"/>                                          " + 
        "       <RECattributes>                                                            " + 
        "           <attribute name=\"USERNAME\" value=\"" + userName + "\"/>              " + 
        "           <attribute name=\"DATA\" value=\"" + userData + "\"/>                  " + 
        "       </RECattributes>                                                           " + 
        "   </REC_DATA>                                                                    " + 
        "]]>                                                                               " ;

        try
        {
            y = new RECPortStub();
            y.sendMsg(mesaj);

        } catch (AxisFault e1)
        {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (RemoteException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

“RECPortStub”类的代码如下;

    static
    {

        _initOperationDesc1();
    }

    private static void _initOperationDesc1()
    {
        org.apache.axis.description.OperationDesc oper;
        org.apache.axis.description.ParameterDesc param;
        oper = new org.apache.axis.description.OperationDesc();
        oper.setName("sendMsg");
        param = new org.apache.axis.description.ParameterDesc(
                new javax.xml.namespace.QName("", "inputXMLMessage"),
                org.apache.axis.description.ParameterDesc.IN,
                new javax.xml.namespace.QName(
                        "http://www.w3.org/2001/XMLSchema", "string"),
                java.lang.String.class, false, false);
        oper.addParameter(param);
        oper.setReturnType(new javax.xml.namespace.QName(

        oper.setStyle(org.apache.axis.constants.Style.RPC);
        oper.setUse(org.apache.axis.constants.Use.ENCODED);
        _operations[0] = oper;

    }

Answer 1

注意：我的问题中的xml格式不正确，但我只是用它来测试，如果 Axis 更改＆＃39;＆lt;＆＃39;＆＃39; ＆GT;＆＃39;字符（转义码）转义字符，如＆＃39;＆lt;＆＃39;和＆＃39;＆gt;＆＃39;在XML的 CDATA部分内。

有两种解决方案;

（简易解决方案）使用 SAAJ 代替 Axis 进行SOAP处理。 SAAJ 不会转义CDATA部分内的字符。
重写Axis方法，以便在XML的CDATA部分内，字符按原样传递而不是转义字符。在CDATA部分之外，小于或大于的字符应该由于xml文档而被转义，但是在CDATA部分内，它们应该按原样传递（据我所知）。

将XML嵌入SOAP请求中的CDATA部分时解析错误
