fastjson Json <-> List<>

起因

json数组,一时间竟然不知道该怎么去解析它了

List转Json

List<Student> students = new ArrayList(); 
String str = JSON.toJSONString(students); 

Json转List

方法一:

String json = ""; //获取的Json数据 
List<Student> students = JSON.parseObject(json,new TypeReference<List<Student>>(){}); 

方法二:

List<Student> students = JSON.parseArray(json,Student.class);
