Jackson可以轻松的将Java对象转换成json对象和xml文档，同样也可以将json、xml转换成Java对象。可以参考：
Jackson 框架，轻易转换JSON
首先需要下载包：jackson-databind-2.0.5.jar jackson-annotations-2.0.5.jar jackson-core-2.0.5.jar，网址在：http://wiki.fasterxml.com/JacksonDownload
custom.json:
{
"country":"USA",
"countryInfo":{"golden":40,"silver":23,"copper":33,"tank":1},
"countryDetail":[
{"id":"no","header":"号码","fieldIndex":"no","sortOrder":null,"printable":true},
{"id":"name","header":"姓名","fieldIndex":"name","sortOrder":null,"printable":true},
{"id":"total","header":"总成绩","fieldIndex":"total","sortOrder":null,"printable":true},
{"id":"detail","header":"详细信息","fieldIndex":"detail","sortOrder":null,"printable":true}
],
"orgood":true}
