CodePudding user response:

ResultType should write the corresponding full path names such as: com. Test. Dao. The User

CodePudding user response:

Try to BaseResultMap

CodePudding user response:

ResultMap to configure the corresponding entity class full name of the class rather than the full name of the class Mapper

CodePudding user response:

But I is a set of return is the List, not a class, write the full path is also one of the error

CodePudding user response:

You are to return to a List The data? Change the map to the map package path
The map - & gt; Java. Util. The Map

In the MAO package path is an error,

CodePudding user response:

# # # Cause: org. Apache. Ibatis. Builder. IncompleteElementException: Could not find the result map. Org. Fkit mapper. UserMapper.

I estimate is written resultMap="org. Fkit. Mapper. UserMapper", should use the resultType="org. Fkit. Mapper. UserMapper"

You still put your code up to look at it

CodePudding user response:

ResultType="map" said returns a map object
Do the key using the column name, value is the value - & gt;

& lt; ! - according to the class id of the class - & gt;
