XStream Framework Use

Original address: http://www.cnblogs.com/hoojo/archive/2011/04/22/2025197.html

XStream Frame

XStream can easily convert Java objects and XML documents to each other, and can modify a particular attribute and node name, and also support the conversion of JSON;

There is an introduction to json-lib this framework, online blog: http://www.cnblogs.com/hoojo/archive/2011/04/21/2023805.html

And the Jackson Framework, online blog: http://www.cnblogs.com/hoojo/archive/2011/04/22/2024628.html

They all support JSON perfectly, but support for XML is not very good. The description of the Java object is limited to a certain extent, and the XML is not fully represented in the description of the Java object. This will introduce XStream's perfect support for JSON and XML. XStream is not only very friendly to the conversion of XML, but also provides annotation annotations, which can be used to describe XML nodes and attributes in JavaBean. As well as JSON support, the conversion can be done with only the relevant jsondriver.

First, the preparatory work

1, download the jar package, and official resources

XStream's jar download address:

Https://nexus.codehaus.org/content/repositories/releases/com/thoughtworks/xstream/xstream-distribution/1.3.1/ Xstream-distribution-1.3.1-bin.zip

The official example is full, official reference example: http://xstream.codehaus.org/tutorial.html

Add the Xstream-1.3.1.jar file to the project, you can start the following work; the required jar is as follows:
