安装

<dependency>

<version>0.17.2</version>
</dependency>

 

 
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
* @author szhu
*/
public class Student implements Comparable<Student>{

/**
* 姓名
*/
private String name;


/**
* 分数
*/
private double score;

public Student(String name, double score) {
this.name = name;
this.score = score;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public double getScore() {
return score;
}

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

@Override
public int compareTo(Student o) {
return Double.compare(this.score, o.score);
}

@Override
public String toString() {
return "Student{" +
"name=\'" + name + \'\\'\' +
", score=" + score +
\'}\';
}
} 

 

2、指定汉语

Faker FAKER = new Faker(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:

import com.github.javafaker.Faker;

import java.util.List;
import java.util.Locale;
import java.util.stream.Collectors;
import java.util.stream.Stream;

/**
* 模型生成工厂
*
* @author szhu
*/
public class ModelFactory {
/**
* faker 指定汉语，默认英语
*/
private static Faker FAKER = new Faker(Locale.CHINA);


/**
* 随机生成一定数量学生
*
* @param number 数量
* @return 学生
*/
public static List<Student> listStudentList(final int number) {
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) throws Exception {
listStudentList(100).forEach(System.out::println);
}

} 

 

运行效果如下
