Gson解析数组和list容器

 

使用Gson解析首先需要加入架包文件：gson-2.2.4.jar

 

定义一个类Student:

public class Student {

String name="xiao";

String sex="男";

}

定义Java文件：

public class ListToGson {

public static void main(String[] args) {

Student[] people= new Student[]{new Student(),new Student(),new Student()};

ArrayList<Student> list = new ArrayList<Student>();

list.add(new Student());

list.add(new Student());

list.add(new Student());

String json = new Gson().toJson(list);

String peoples = new Gson().toJson(people);

System.out.println(json);

System.out.println(peoples);

}
}

运行结果如下：

对list解析：[{"name":"xiao","sex":"男"},{"name":"xiao","sex":"男"},{"name":"xiao","sex":"男"}]

对数组解析：[{"name":"xiao","sex":"男"},{"name":"xiao","sex":"男"},{"name":"xiao","sex":"男"}]
