JavaBean转化为Map，List<JavaBean>转化为List<Map>

   /**
     * 将对象转化为map
     *
     * @param bean
     * @param <T>
     * @return
     */
    private <T> Map<String, Object> beanToMap(T bean) {
        Map<String, Object> map = Maps.newHashMap();
        if (bean != null) {
            BeanMap beanMap = BeanMap.create(bean);
            for (Object key : beanMap.keySet()) {
                map.put(key.toString(), beanMap.get(key));
            }
        }
        return map;
    }

    /**
     * 将list<JavaBean>转化为List<Map<String, Object>>
     *
     * @param objList
     * @param <T>
     * @return

    private <T> List<Map<String, Object>> objectsToMaps(List<T> objList) {
        List<Map<String, Object>> list = Lists.newArrayList();
        if (objList != null && objList.size() > 0) {
            Map<String, Object> map = null;
            T bean = null;
            for (int i = 0, size = objList.size(); i < size; i++) {
                bean = objList.get(i);
                map = beanToMap(bean);
                list.add(map);
            }
        }
        return list;
    }

主要就是

通过net.sf.cglib.beans.BeanMap类中的方法，原理几乎都是反射
