XStream

您可以在Wikipedia上了解到此条目的英文信息 XStream Thanks, Wikipedia.

XStream是一个开源(BSD) Java类库，用来将对象序列化成XML、JSON或反序列化为对象。

Features

Ease of use. A high level facade is supplied that simplifies common use cases.
No mappings required. Most objects can be serialized without need for specifying mappings.
Performance. Speed and low memory footprint are a crucial part of the design, making it suitable for large object graphs or systems with high message throughput.
Clean XML. No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
Requires no modifications to objects. Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
Full object graph support. Duplicate references encountered in the object-model will be maintained. Supports circular references.
Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
Customizable conversion strategies. Strategies can be registered allowing customization of how particular types are represented as XML.
Error messages. When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem.
Alternative output format. The modular design allows other output formats. XStream ships currently with JSON support and morphing.

下面是xml与java对象互转的代码。

Xstream  xs = new Xstream();
String xml = xs.toXML(foo);
Foo foo = (Foo)xs.FromXML(xml);

XStream也用Jettison做driver，支持Java对象与JSON的序列化

XStream xstream = new XStream(new JettisonMappedXmlDriver());
