mybatis使用map传递多参数报错:A query was run and no Result Maps were found for the Mapped Statement

在使用mybatis进行多参数传递时,报错:

A query was run and no Result Maps were found for the Mapped Statement 'xx.xx.'.  It's likely that neither a Result Type nor a Result Map was specified.

 

后来发现,原来是没有指定resultMap或resultType

mybatis中的所有查询,都必须返回resultType或者resultMap的值,否则就会报如上错误的。

到此,问题就解决了。

可是我又好奇了,resultMap怎么使用呢?

这就涉及到多表联查

请看下文!
