Mapping query results to Java objects: ResultMap can simplify developers’ data conversion work by mapping query results to properties in Java objects.
To handle duplicate column names in query results, you can use ResultMap to specify mapping rules, preventing unrecognized column names from occurring.
Handling complex mapping relationships: When there are complex association relationships in the query results, ResultMap can be used to define the mapping relationships between multiple tables, achieving complex data mapping.
Customize the mapping rules for query results: ResultMap allows you to customize the mapping rules for query results, including mapping field names and type conversion, achieving flexible data mapping functionality.
Improve query efficiency: By using ResultMap correctly, you can enhance query efficiency, avoid unnecessary data transformation and processing, and optimize query performance.
