java - 替换axis2响应

Question

之前，我确实使用 axis 为我的 Web 服务实现了一个处理程序，该处理程序将读取 xml 文件并将其作为响应返回。我的代码如下:

try {
        Message msg = msgContext.getResponseMessage();
        MessageContext context = MessageContext.getCurrentContext();



        InputStream in = this.getClass().getClassLoader().getResourceAsStream("login_rsp_xml");
        if(in==null){

            System.out.println("in is empty!!!");
        }
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory
                .newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(in);
        msg.getSOAPPart().setContent(new DOMSource(doc));
        System.out.println("return file>>"+fileName);

    } catch (Exception e) {
        System.setProperty("req_no", null);
        e.printStackTrace();            
    }

现在，我需要使用 axis2 做同样的事情。有谁知道如何替换 axis2 中的传出响应？我确实尝试将文件转换为字符串并调用 Envelope.setText()，但失败并出现异常“org.apache.axiom.soap.SOAPProcessingException:无法分离 SOAP 正文，SOAP 信封必须有正文! ”。

预先感谢您的帮助/建议。

                .getResourceAsStream(path);

        DocumentBuilderFactory dbFactory = DocumentBuilderFactory

        StringWriter writer = new StringWriter();
        transformer
                .transform(new DOMSource(doc2), new StreamResult(writer));
        String output2 = writer.getBuffer().toString();

        return output2;
    }

    public InvocationResponse invoke(MessageContext msgContext)
            throws AxisFault {
        System.out.println("In Response");


        String content = msgContext.getEnvelope().toString();

        try {

            System.out.println("zzzz>>"+System.getProperty("abc"));         


            msgContext.getEnvelope().setText("abc");
        } catch (Exception e) {
            e.printStackTrace();
        }

        return InvocationResponse.CONTINUE;
    }

    public void revoke(MessageContext msgContext) {

    }


}

如果您要在 SOAP 响应中设置 XML 文件，则必须将其包含在 <![CDATA[]>标签。这是为了防止 XML 文件作为 SOAP 响应的一部分进行处理。请注意，SOAP 还使用 XML 来处理请求和响应。

<![CDATA[
    <?xml version="1.0"?>
    <!-- Your XML -->
]>

按照上面的方法创建 XML 文件并将其设置为 envelope.setText()
