4.导出excel文件总结：
（1）所需jar包：
（2）exportExcel()方法：
这个方法使用与生成文件名和sheet名（即列表名），设置map是为了接收查询条件的。
其中调用了argMap()方法，是用来添加查询条件用于限制结果集的；
调用findAllObject()方法，是用来查找满足条件的对象的，将所有满足条件的对象放入list中；
然后调用了生成excel文件并触发下载的generateExcel()方法。
（3）argMap(Map<String,Object> map)方法：
此方法用于将页面中需要查询的条件及search_username和search_password放入map集合中封装起来。
（4）findAllObject(Map<String, Object> map)方法：
此方法通过封装好的查询条件：map中的值来拼装出hql语句，然后通过调用find() 方法来查找出，所有符合此条件查询的对象放入list集合中。
（5）generateExcel(list,excelName, sheetName)方法：
此方法用于创建excel文件，生成成功后触发下载。
