【工具包】测试实体对象一键生成

介绍

根据传入的对象类生成对象，并随机赋值

嗯就是闲的蛋疼

使用方式

1.准备个实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserType {
    private int aid;//	权限ID
    private String aName;//权限名
}

2.使用类

@Test
public void text05() {
    Object o = DataUtils.textUtils(Car.class);
    System.out.println(o);
}

3.结果

工具方法源码

    //测试工具
    public static <T> Object textUtils(Class<T> clazz) {
        T t = null;
        try {
            Constructor<T> c = clazz.getConstructor();
            t = c.newInstance();
            Field[] declaredFields = clazz.getDeclaredFields();
            for (Field field : declaredFields) {
                PropertyDescriptor pd = new PropertyDescriptor(field.getName(), clazz);
                Method getWriteMethod = pd.getWriteMethod();
                Class<?>[] parameterTypes = getWriteMethod.getParameterTypes();
                if (parameterTypes.length == 1) {
                    String typeName = parameterTypes[0].getSimpleName();
                    if (typeName.equals("int")) {
                        getWriteMethod.invoke(t, (int) (Math.random() * 10));
                    }
                    if (typeName.equals("float")) {
                        getWriteMethod.invoke(t, 10.00f);
                    }
                    if (typeName.equals("String")) {
                        getWriteMethod.invoke(t, "text" + (int) (Math.random() * 10));
                    }
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return t;
    }
