public class XStreamMarshaller extends AbstractMarshaller implements BeanClassLoaderAware, InitializingBean
Implementation of theMarshallerinterface for XStream.By default, XStream does not require any further configuration and can (un)marshal any class on the classpath. As such, it is not recommended to use the
XStreamMarshallerto unmarshal XML from external sources (i.e. the Web), as this can result in security vulnerabilities. If you do use theXStreamMarshallerto unmarshal external XML, set thesupportedClassesandconvertersproperties (possibly using aCatchAllConverter) or override thecustomizeXStream(XStream)method to make sure it only accepts the classes you want it to support.Due to XStream's API, it is required to set the encoding used for writing to OutputStreams. It defaults to
UTF-8.NOTE: XStream is an XML serialization library, not a data binding library. Therefore, it has limited namespace support. As such, it is rather unsuitable for usage within Web Services.
This marshaller requires XStream 1.4.5 or higher, as of Spring 4.3. Note that
XStreamconstruction has been reworked in 4.0, with the stream driver and the class loader getting passed into XStream itself now.- 从以下版本开始:
