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！
