Precautions:

1.XStream There are some small bugs, in the definition of the alias in the underscore "_" after the conversion to XML will become "__" This symbol, the underscore problem can be resolved with the following

XStream XStream = new XStream (new Xppdriver (New Xmlfriendlynamecoder ("_-", "_"));

It can also be used as a test class: ReplaceAll ("__", "_"); Replace
