XStream Framework

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

Previous Json-lib this framework, online blog: http://www.cnblogs.com/hoojo/archive/2011/04/21/2023805.html

And Jackson this 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. To some extent, the description of the Java object is limited, and the XML is not fully embodied in the description of the Java object. Here's how XStream's best support for JSON and XML is covered. XStream is not only very friendly to the transformation of XML, but also provides annotation annotations, which can be used to describe XML nodes and attributes in JavaBean. and also support for JSON, you can complete the conversion simply by providing the relevant jsondriver.

First, preparatory work

1, download jar package, and official resources

XStream 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 and you can start the work below; the required jar is as follows:
