对象拷贝、实体转Map

实体转Map返回map对象：

import org.springframework.cglib.beans.BeanMap;
BeanMap.create(entityObj);

借助springframework对象拷贝

import org.springframework.beans.BeanUtils;

public class Utils {

    /**
     * 对象拷贝
     *
     * @param source 源对象
     * @param target 希望拷贝成为的类型
     * @param <T>    任意object
     * @return 拷贝后的新对象
     */
    public static <T> T copyProperties(Object source, Class<T> target) {
        if (target == null) {
            return null;
        }
        T targetInstance = null;
        try {
            targetInstance = target.newInstance();
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (source == null) {
            return targetInstance;
        }
        BeanUtils.copyProperties(source, targetInstance);
        return targetInstance;
    }
}
