我想修改传出的 SOAP 请求。 我想从信封的正文中删除 2 个 xml 节点。 我设法设置了一个拦截器并将消息的生成字符串值设置为端点。
但是,以下代码似乎无法正常工作,因为传出消息未按预期进行编辑。有没有人有关于如何执行此操作的一些代码或想法?
public class MyOutInterceptor extends AbstractSoapInterceptor {
public MyOutInterceptor() {
super(Phase.SEND);
}
public void handleMessage(SoapMessage message) throws Fault {
// Get message content for dirty editing...
StringWriter writer = new StringWriter();
CachedOutputStream cos = (CachedOutputStream)message.getContent(OutputStream.class);
InputStream inputStream = cos.getInputStream();
IOUtils.copy(inputStream, writer, "UTF-8");
String content = writer.toString();
// remove the substrings from envelope...
content = content.replace("<idJustification>0</idJustification>", "");
content = content.replace("<indicRdv>false</indicRdv>", "");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
outputStream.write(content.getBytes(Charset.forName("UTF-8")));
message.setContent(OutputStream.class, outputStream);
}
最佳答案
根据第一条评论,我创建了一个抽象类,可以轻松用于更改整个肥皂信封。
以防万一有人想要现成的代码部分。
