/**
 * map to bean
 * 转换过程中，由于属性的类型不同，需要分别转换。
 * java 反射机制，转换过程中属性的类型默认都是 String 类型，否则会抛出异常，而 BeanUtils 项目，做了大量转换工作，比 java 反射机制好用
 * BeanUtils 的 populate 方法，对 Date 属性转换，支持不好，需要自己编写转换器
 *
 * @param map  待转换的 map
 * @param bean 满足 bean 格式，且需要有无参的构造方法; bean 属性的名字应该和 map 的 key 相同
 * @throws IllegalAccessException
 * @throws InvocationTargetException
