Jmockdta是一款实现模拟JAVA类型或对象的实例化并随机初始化对象的数据的工具框架。
The plugin of Jmockdata what through random algorithm mock java data.
Jmockdata插件通过随机算法模拟Java数据.
- 支持丰富多样的数据类型模拟，包括：Java基本类型、字符串、枚举、日期、数组、多维数组、集合[List|Set|Map]、枚举、Java对象等
- 支持通过正则表达式反向模拟数据
- 支持泛型
- 支持继承
- 支持循环依赖、自依赖(手动开启enabledCircle)
- 支持忽略字段
- 支持改变mockConfig来自定义模拟数据策略
- 支持自定义Mocker类
- 支持JDK1.8+

支持以下基础类型直接模拟
| 描述 | 类型 |
|---|---|
| 基础类型 | byte boolean char short int long float double |
| 包装类型包装 | Byte Boolean Character Short Integer Long Float Double |
| 常用类型 | BigDecimal BigInteger Date LocalDateTime LocalDate LocalTime java.sql.Timestamp String Enum |
| 多维数组 | 以上所有类型的多维数组 如：int[] int[][] int[][][] .... etc. |
//基本类型模拟
int intNum = JMockData.mock(int.class);
int[] intArray = JMockData.mock(int[].class);
Integer integer = JMockData.mock(Integer.class);
Integer[] integerArray = JMockData.mock(Integer[].class);
//常用类型模拟
BigDecimal bigDecimal = JMockData.mock(BigDecimal.class);
BigInteger bigInteger = JMockData.mock(BigInteger.class);
Date date = JMockData.mock(Date.class);
String str = JMockData.mock(String.class);模拟bean，被模拟的数据最好是plain bean，通过反射给属性赋值。
支持模拟继承而来的属性。
