总得来说,单个参数不用说,多个参数不是通过具体的Entity就是通过Map。
Q:能不能用逗号隔开传递parameterType="java.lang.String,java.lang.String"?

More:When you say interface I hope you mean your mapper interface. If so
you just need to name your parameters with the @Param annotation.
This will then place the parameters into a map for you. You can
actually just leave off the parameterType attribute it you want. It
is not check nor enforced. I like to use them just to be able to see
what is coming in. "map" should still work for you.
parameterType不是必须出现在XML的语句里的,它既不用来检查什么也不是强制的关键字,完全可以抛弃不写。
要想传两个参数,只需要用@Param修饰一下参数的名字,底层框架就会把他们封装到"map"类型里了(也就是说你都不用自己搞什么new XXMap()的工作)。
本人也用代码验证过了,超过1个参数,必须得用@Param修饰一下(并且得给参数指定一个与在XML中使用时相同的名字)。
