lts-admin 日志/节点上下线日志搜索弹出错误对话框问题 #434
Description
lts-admin登入后台后，点击日志/节点上下线日志菜单，默认无条件搜索正常，但是当节点组输入某个字符串时，点击搜索，则会弹出一个错误展示层，经过查看日志记录，发现是lts-admin的一个sql bug。
错误代码坐标：com.github.ltsopensource.admin.access.mysql.MysqlBackendNodeOnOfflineLogAccess#buildWhereSql 99行。
报错信息：
com.github.ltsopensource.store.jdbc.exception.JdbcException: Select SQL Error:
SELECT

FROM
`lts_admin_node_onoffline_log`
WHERE
GROUP = ?
AND event = ?

错误原因：
查询语句有个字段名group，但这个是个sql关键字，所以翻译后的sql无法被正确解析，故而报错。
解决方案：
第99行，
将 .andOnNotEmpty("group = ?", request.getGroup())
改为 .andOnNotEmpty("`group` = ?", request.getGroup())即可。
