Xstream Ignore Unknown Elements


For this kind of work a data binding tool such as XMLBeans is appropriate. Hibernate Envers is an optional dependency for XStream and it is automatically supported by XStream's Hibernate package when the proxy collection types of Envers are available on the classpath.

You can enable CGLIB support with: XStream xstream = new XStream() { protected MapperWrapper wrapMapper(MapperWrapper next) { return new CGLIBMapper(next); } }; xstream.registerConverter(new CGLIBEnhancedConverter(xstream.getMapper(), xstream.getReflectionProvider())); CGLIBEnhancedConverter fails at initialization with ExceptionInInitializerError http://helpsbs.com/not-working/xstream-alias-example.html

By configuring the XStream with the XStream.addImplicitCollection(), XStream.addImplicitArray(), and XStream.addImplicitMap() methods it is possible to keep the elements directly as child of the class and the surrounding tag for the container Well, no, the JSON is valid! A reflection based converter will now ignore any unknown XML elements (i.e. forumItem.setPostedDate( SearchDataUtils.convertStringToDate(post.getPostedDate(),"yyyy-MM-dd hh:mm:ss")); forumItem.setUpdateDate(

Xstream Ignore Unknown Elements

Use XStream to transfer your objects into XML. When serializing to JSON or XML with xstream-1.3 I have trouble omitting fields from the output. Why is there no SaxReader? My parser claims the � character to be invalid, but it was written with XStream!

XStream maps Java class names and field names to XML tags or attributes. The resulting XML is now what we have expected: 15 If you let XStream process the annotations of a type, it will also process all annotations of the related Attributes The client may asks for the type tag and the importance flag to be an attribute inside the message tag, as follows: firstPart secondPart 1154097812245 All Xstream Implicit Collection The only issue i have is that if the xml response by a third party by chance have an element in our case like which we were not aware of xstream

Now instead of String our object is populated with Date instance. @xstreamomitfield Suddenly the deserialization of my (serializable) lambda expression fails! Therefore it contains class files targeting different JDKs. In consequence it is possible to adjust the processed XML manually to inject arbitrary objects into the deserialized object graph.

a TreeSet with a Comparator) cannot be restored, since the comparator was already omitted at serialization time. Xstream Alias Not Working If a field is removed from the class, deserializing an old version that contains the field will cause an exception. Which versions of Jettison are supported? I added @XStreamAsAttribute to add xmlns as an attribute .


Therefore XStream can handle quite any class, especially the ones referred as POJO (Plain Old Java Object). asked 4 years ago viewed 10300 times active 2 years ago Upcoming Events 2016 Community Moderator Election ends in 6 days Blog How We Make Money at Stack Overflow: 2016 Edition Xstream Ignore Unknown Elements I realize there is an omitField method but that seems only to be for the serialization side of things.

XStream has no control over this information and how it is used by native functionality in the JDK. Since XStream verison 1.4.7 it does no longer handle an EventHandler automatically. Such referenced can exist though for persisted streams when a type is added as immutable in later versions. My parser claims a control character to be invalid, but it was written with XStream! Xstream Annotations

Serialization fails with NoSuchMethodError: net.sf.cglib.proxy.Enhancer.isEnhanced(Ljava/lang/Class;)Z XStream uses this method to detect a CGLIB-enhanced proxy. JavaScript does not know about integer values. Therefore we need to tell XStream to read the annotations from this type: public static void main(String[] args) { XStream stream = new XStream(); xstream.processAnnotations(RendezvousMessage.class); RendezvousMessage msg = new RendezvousMessage(15); System.out.println(stream.toXML(msg)); http://helpsbs.com/not-working/xstream-annotations.html I cannot get omitField to ignore a field upon > deserialization. > > Here is a test program which demonstrates my confusion: > > public class XStreamOmitTest { >

Depending on the use case it is fortunate to use specialized converters for own types, mapper implementations that control naming of things more globally or use specialized writers to influence the Xstream Namespace Dom4JDrivernoDriver turns off DOCTYPE processing to suppress handling of external entities with SAX reader in use.

Can immutable types be referenced?

Reply ↓ Ankit Dhingra on May 31, 2012 at 6:01 AM said: The omit method will work only when you know which fields are extra. But exactly in this case the developer knows very well the elements to ignore and that's where he can use the omitField method. > Or would this violate too many of The alias mechanism described above is implemented as such a mapper that can be configured. Xstream Optional Element However, the nodep version contains a copy of the ASM classes with private packages and will therefore not raise class incompatibilities at all.

This is especially true when running XStream in an applet. Note, that you cannot use your own objects, you have to use what is generated. in this mode a StreamException is thrown. Check This Out A character of value 0 is not valid as part of XML according the XML specification (see version 1.0 or 1.1), neither directly nor as character entity nor within CDATA.

Which JVMs allow XStream to operate in enhanced mode? Example Look at the following stylesheet: It is used here to remove the age of the How much memory does XStream consume?
