com.thoughtworks.xstream.converters.ConversionExcepti

XStream xstream = new XStream(new JettisonMappedXmlDriver());
xstream.alias("teachers", List.class);
String json =
"{'teachers': [ {'id': 1, 'name': 'Rose'}, { 'id': 3, 'name': 'Tony' } ]}";
System.out.println(xstream.fromXML(json));


上面的代码报告一个错误：
