+     *               某个角色权限的人，可以在此处进行账户选择，根据实例化参数的不同来区分
+     *    举例：     选择某个工厂的一个账户，需要这么实例化：FormAccountSelect form = new FormAccountSelect("分厂示例一",1,1,null)
+     *               选择某个角色的一个账户，需要这么实例化：FormAccountSelect form = new FormAccountSelect("2487f33a8f22408ca4bbca5456a7eecb",1,1,null)
+     *               两者区分的条件是判断字符串的长度是否大于等于16
+     *               如果允许选择所有的账户的一个账户，需要这么实例化：FormAccountSelect form = new FormAccountSelect("",1,1,null)
+     *               当然也支持选择多个账户，直至选择完成所有的账户
