使用fastjsonlist和String互转

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

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

List<Student> students = JSON.parseArray(json,Student.class); 
Student 对象要实现Serializable接口
import java.io.Serializable;  
public class Student implements Serializable{ }
