spring mybatis - Failed to parse mapping resource

I made a boardContentMap in clubMapper.xml, but I don't know why they can't find it.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in ServletContext resource [/WEB-INF/spring/root-context.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [C:\workspace_springProject.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\controller\WEB-INF\classes\mappers\clubMapper.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'boardContentMap'. Cause: java.lang.ClassNotFoundException: Cannot find class: boardContentMap
