java生成假数据--javafaker

1.前言

在工作中我们总是避免不了需要一些测试数据的支持，可是动辄成千上万条的数据编写起来让我们头痛不已，尤其是一些刁钻的场景还需要“假数据”不那么“假”，因此我们可以使用javafaker来实现假数据的制作。

3.javafaker使用方法

3.1引入包

<dependency>
    <groupId>com.github.javafaker</groupId>
    <artifactId>javafaker</artifactId>
    <version>1.0.2</version>
</dependency>

3.2代码示例

Faker faker = new Faker();		//创建JavaFaker对象

String name = faker.name().fullName(); // Miss Samanta Schmidt
String firstName = faker.name().firstName(); // Emory
String lastName = faker.name().lastName(); // Barton

String streetAddress = faker.address().streetAddress(); // 60018 Sawayn Brooks Suite 449

3.3 根据需要创建不同国家的javafaker对象

Faker faker = new Faker(new Locale("YOUR_LOCALE"));
//示例：如果想使用中国的数据
Faker faker = new Faker(Locale.CHINA);
