安装

com.github.javafaker

javafaker

0.17.2

使用

随机生成一百个学生及考生分数

学生模型

/*** 测试model 学生

*@authorszhu*/

public class Student implements Comparable{/*** 姓名*/

privateString name;/*** 分数*/

private doublescore;public Student(String name, doublescore) {this.name =name;this.score =score;

}publicString getName() {returnname;

}public voidsetName(String name) {this.name =name;

}public doublegetScore() {returnscore;

}public void setScore(doublescore) {this.score =score;

}

@Overridepublic intcompareTo(Student o) {return Double.compare(this.score, o.score);

}

@OverridepublicString toString() {return "Student{" +

"name='" + name + '\'' +

", score=" + score +

'}';

}

}

2、指定汉语

Faker FAKER = newFaker(Locale.CHINA);

中文姓名

FAKER.name().fullName();1~100之间两位小数数字

FAKER.number().randomDouble(2, 1, 100)

具体如下:

importcom.github.javafaker.Faker;importjava.util.List;importjava.util.Locale;importjava.util.stream.Collectors;importjava.util.stream.Stream;/*** 模型生成工厂

*

*@authorszhu*/

public classModelFactory {/*** faker 指定汉语，默认英语*/

private static Faker FAKER = newFaker(Locale.CHINA);/*** 随机生成一定数量学生

*

*@paramnumber 数量

*@return学生*/

public static List listStudentList(final intnumber) {return Stream.generate(() -> new Student(FAKER.name().fullName(), FAKER.number().randomDouble(2, 1, number))).limit(number).collect(Collectors.toList());

}/*** main函数*/

public static void main(String[] args) throwsException {

listStudentList(100).forEach(System.out::println);

}

}
