关于将对象列表直接转为json数组
代码如下:
import java.util.ArrayList; import java.util.List; import com.google.gson.Gson; public class JsonTest { public static void main(String[] args) { Person p1 =new Person("1", "zhangsan"); Person p2 =new Person("2", "lisi"); List<Person> list = new ArrayList<Person>(); list.add(p1); list.add(p2); Gson gson = new Gson(); String result = gson.toJson(list); System.out.println(result);//[{"id":"1","name":"zhangsan"},{"id":"2","name":"lisi"}] } } class Person{ private String id; private String name; public Person(String id, String name) { this.id = id; this.name = name; } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
