Add

import org.apache.ibatis.annotations.Mapper;

@Mapper
@DS("source1")
public interface UserMapper {

    @Select("select user_name, count(1) from user group by user_name")
    Map<String, Integer> getUserCountByName();
}

After hot reload, execute the newly added UserMapper#getUserCountByName to use the source1 data source.

Modify

import org.apache.ibatis.annotations.Mapper;

@Mapper
@DS("source1") 
@DS("source2") 
public interface UserMapper {

    @Select("select user_name, count(1) from user group by user_name")
    Map<String, Integer> getUserCountByName();
}

After hot reload, execute the newly added UserMapper#getUserCountByName to switch from source1 to source2 data source.
