在SqlHelper的getAllColumns方法获取所有column时增加Delimiter包裹字段避免和sql保留字段冲突

1

如题。当用在一些设计不完美的数据库上时，会有sql关键字冲突，如果加上 ` 包裹字段，就可以解决此问题。

@abel533,前辈您好! --- 使用您的分页插件时出现了问题.以下是出现的问题和自己的配置以及代码 报错信息  Spring boot的application.properties  改成Javaconfig的方式配置Pagehelper可以注册这个Pagehelper但是调用时依然会报空指针异常,请大神看下是什么原因 代码块:  --- 2017-11-29 00:10:33 更新 采用spring配置SqlSessionFactoryBean获取sessionfactory依然可以,但是仍然报以上的错. pagehelper拦截器  sessionfactory  Springboot启动类  resources下和mybatis相关的只有MBG了  折腾了一晚上实在不知道到底哪里出了问题了,前辈求指导,谢谢您~.~

大神, 请问可以在controller层动态设置pagesize吗?

public PageInfo getAll( City city ) { List countryList = cityService.getAll( city ); return new PageInfo( countryList ); } 比如我想每页显示5条, 在查出list以后, 返回之前设置怎么搞?
