## Usage

### 基础类型

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``` |

  private String[] stringArray;
  //其他常用类型二维数组
  private BigDecimal[][] bigDecimalDoubleArray;
  private BigInteger[][] bigIntegerDoubleArray;
  private Date[][] dateDoubleArray;
  private String[][] stringDoubleArray;
  //集合、MAP数组
  private List<Integer>[] listArray;

  //集合、MAP二维数组(内部二维数组)
  private List<Integer[][]>[][] listInnerDoubleArrayDoubleArray;
  private Set<Integer[][]>[][] setInnerDoubleArrayDoubleArray;
  private Map<Integer[][], String[][]>[][] mapInnerDoubleArrayDoubleArray;
  //LIST
  private List<Byte> byteBoxingList;
  private List<Boolean> booleanBoxingList;
  private List<Character> charBoxingList;
  private List<Short> shortBoxingList;
  private List<Integer> integerBoxingList;
  private List<Long> longBoxingList;
  private List<Float> floatBoxingList;
  private List<Double> doubleBoxingList;

  private List<BigInteger[][]> bigIntegerDoubleArrayList;
  private List<Date[][]> dateDoubleArrayList;
  private List<String[][]> stringDoubleArrayList;
  //SET忽略同List
  //MAP
  private Map<String, Integer> basicMap;
  private Map<String[], Integer> keyArrayMap;
  private Map<String, Integer[]> valueArrayMap;
  private Map<String[], Integer[]> keyValueArrayMap;
  private Map<String[][], Integer[][]> keyValueDoubleArrayMap;
  private Map<List<String>, Map<String, Integer>> keyListValueMapMap;
  private Map<List<String>[], Map<String, Integer>[]> keyArrayListValueArrayMapMap;
  //getter setter省略...
}

//调用模拟数据的方法模拟Java对象
BasicBean basicBean = JMockData.mock(BasicBean.class);
```
### 容器类型（LIST,SET,MAP）

```java
@Test
//******注意TypeReference要加{}才能模拟******
public void testTypeRefrence() {
  //模拟基础类型，不建议使用这种方式，参考基础类型章节直接模拟。
  Integer integerNum = JMockData.mock(new TypeReference<Integer>(){});
  Integer[] integerArray = JMockData.mock(new TypeReference<Integer[]>(){});
  //模拟集合
  List<Integer> integerList = JMockData.mock(new TypeReference<List<Integer>>(){});
  //模拟数组集合
  List<Integer[]> integerArrayList = JMockData.mock(new TypeReference<List<Integer[]>>(){});
  //模拟集合数组
  List<Integer>[] integerListArray = JMockData.mock(new TypeReference<List<Integer>[]>(){});
  //模拟集合实体
  List<BasicBean> basicBeanList = JMockData.mock(new TypeReference<List<BasicBean>>(){});
  //各种组合忽略。。。。map同理。下面模拟一个不知道什么类型的map
  Map<List<Map<Integer, String[][]>>, Map<Set<String>, Double[]>> some = JMockData.mock(new TypeReference<Map<List<Map<Integer, String[][]>>, Map<Set<String>, Double[]>>>(){});
}
```

### 更改随机范围以及排除某些不模拟数据的字段
#### 字段支持三种模式匹配，可快速配置：[\*FieldWord\*]、[\*FieldWord]、[FieldWord\*]
```java
MockConfig mockConfig = new MockConfig()
            // 全局配置
            .globalConfig()
            .setEnabledStatic(false);
            .setEnabledPrivate(false);
            .setEnabledPublic(false);
            .setEnabledProtected(false);
            .sizeRange(1,1)
            .charSeed((char) 97, (char) 98)
            .byteRange((byte) 0, Byte.MAX_VALUE)
            .shortRange((short) 0, Short.MAX_VALUE)

// 某些字段（名等于integerNum的字段、包含float的字段、double开头的字段）配置
            .subConfig("integerNum","*float*","double*")
            .intRange(10, 11)
            .floatRange(1.22f, 1.50f)
            .doubleRange(1.50,1.99)

// 某个类的某些字段（long开头的字段、date结尾的字段、包含string的字段）配置。
            .subConfig(BasicBean.class,"long*","*date","*string*")
            .longRange(12, 13)
            .dateRange("2018-11-20", "2018-11-30")
            .stringSeed("SAVED", "REJECT", "APPROVED")
            .sizeRange(1,1)

// 全局配置
            .globalConfig()
            // 排除所有包含list/set/map字符的字段。表达式不区分大小写。
            .excludes("*List*","*Set*","*Map*")
            // 排除所有Array开头/Boxing结尾的字段。表达式不区分大小写。
            .excludes(BasicBean.class,"*Array","Boxing*");
    BasicBean basicBean = JMockData.mock(BasicBean.class, mockConfig);
```

## 高级特性
### 设置小数位数
```java
 public void testDecimalScaleMock() {
    MockConfig mockConfig = new MockConfig()
            .doubleRange(-1.1d,9999.99999d)
            .floatRange(-1.11111f,9999.99999f)
            .decimalScale(3) // 设置小数位数为3，默认是2
            .globalConfig();
    JMockData.mock(BigDecimal.class,mockConfig);
  }
 ```

### 根据正则模拟数据
#### 支持\w \W \d \D \s \S
#### 支持\[0-9a-zA-Z\] \[abc123_\]
#### 支持{n} {n,} {n,m}
#### 支持 * + . ?
#### 不支持其他，如() ^ $ | \n \t \cx \b \B \f 等等

```java

/**
    * 根据正则模拟数据
    * 正则优先于其他规则
    */
   @Test
   public void testRegexMock() {
     MockConfig mockConfig = new MockConfig()
                 // 随机段落字符串
                 .stringRegex("I'am a nice man\\.And I'll just scribble the characters, like：[a-z]{2}-[0-9]{2}-[abc123]{2}-\\w{2}-\\d{2}@\\s{1}-\\S{1}\\.?-.")
                 // 邮箱
                 .subConfig(RegexTestDataBean.class,"userEmail")
                 .stringRegex("[a-z0-9]{5,15}\\@\\w{3,5}\\.[a-z]{2,3}")
                 // 用户名规则
                 .subConfig(RegexTestDataBean.class,"userName")
                 .stringRegex("[a-zA-Z_]{1}[a-z0-9_]{5,15}")
                 // 年龄
                 .subConfig(RegexTestDataBean.class,"userAge")
                 .numberRegex("[1-9]{1}\\d?")
                 // 用户现金
                 .subConfig(RegexTestDataBean.class,"userMoney")
                 .numberRegex("[1-9]{2}\\.\\d?")
                 // 用户的得分
                 .subConfig(RegexTestDataBean.class,"userScore")
                 .numberRegex("[1-9]{1}\\d{1}")
                 // 用户身价
                 .subConfig(RegexTestDataBean.class,"userValue")
                 .numberRegex("[1-9]{1}\\d{3,8}")
                 .globalConfig();

}

```

### 循环依赖

```java
public class AXB {
  private BXA BXA;
  private String name;
  //getter setter省略...
}
public class BXA {
  private AXB AXB;
  private String name;
  //getter setter省略...
}
@Test
public void testCircular() {
   AXB axb = JMockData.mock(AXB.class);
   AXB circularAxb = axb.getBXA().getAXB();
   assertSame(axb, circularAxb);
}
```

### 自依赖

```java
public class SelfRefData {

private Integer id;
  private String name;
  private SelfRefData parent;
  private Map<SelfRefData, SelfRefData> parentMap;
  private SelfRefData[] parentArray;
  private List<SelfRefData> list;
  private List<SelfRefData[]> listArray;
  private List<List<SelfRefData[]>> listListArray;
  private List<SelfRefData>[] arrayList;

private SelfRefData[][][] data;
  private Map<SelfRefData, SelfRefData[]> mapArray;
  private Map<SelfRefData, List<SelfRefData>> mapList;
  private Map<SelfRefData, List<SelfRefData[]>> mapListArray;
  //getter setter省略...
}
@Test
public void testSelf() {
   SelfRefData selfRefData = JMockData.mock(SelfRefData.class);
   assertSame(selfRefData.getParent(), selfRefData);
}
```

### 泛型继承

```java
//定义一个泛型父类
public class GenericData<A, B, C> {
  private A a;
  private B b;
  private C c;
  private A[] aArray;
  private List<B> bList;
  private Map<A, B> map;
  private List<C>[] cArray;
  private Map<Map<A, B>, List<C>>[] d;
  //getter setter省略...
}

@Test
public void testGenericData() {
    GenericData<Integer, String, BasicBean> genericData = JMockData.mock(new TypeReference<GenericData<Integer, String, BasicBean>>() {});
    assertNotNull(genericData);
  }
```

### 自定义Mocker类注册

```java
MockConfig mockConfig = new MockConfig()
            .registerMocker(Mocker mocker, Class<T>... clazzs)

```

### 定义BeanMocker拦截器
##### 通过实现接口BeanMockerInterceptor实现模拟bean时拦截功能，改变模拟行为
#### 拦截器返回值类型说明:
- 返回InterceptType.UNMOCK 不模拟, 排除此字段的模拟
- 返回InterceptType.MOCK 自动模拟
- 其他返回值，作为field的值通过反射注入

```java
MockConfig mockConfig = new MockConfig()
           .registerBeanMockerInterceptor(new BeanMockerInterceptor() {...}) // 全局拦截
           .registerBeanMockerInterceptor(SimpleBean.class,new BeanMockerInterceptor<SimpleBean>() {...})// 类型拦截

```
