Question

java怎么将json对象转换成json数组

Answer 1

1、需要json的相关jar包

2、设置json格式字符串：

String str="{\"student\":[{\"name\":\"leilei\",\"age\":23},{\"name\":\"leilei02\",\"age\":23}]}";

3、建立相应的类：

public class StudentList {
List<Student> student;
public List<Student> getStudent() {
return student;
}

public void setStudent(List<Student> student) {
this.student = student;
}
}

public class Student {
private String name;
private int age;
//private StudentClass studentClass;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}

4、测试程序

import java.util.List;
import org.codehaus.jackson.map.ObjectMapper;
