Result Map In Mybatis. Create POJO objects according to the database field as far as possible to avoid the processing of complex results. Resultmap deals with one to many many to one is the key and difficult point.
Result Maps are the answer that MyBatis provides to this problem. In MyBatis when a query is select ed for mapping the return type can be either resultType or resultMap which is a direct representation of the return type while resultMap is a reference to the external ResultMap but resultType and resultMap cannot exist simultaneously. Im triying to work with conditional in my resultmaps but I think that.
Modifier and Type Class and Description.
Once the result map is defined we can refer these from several SELECT statements. This helps to improve general performance but especially performance of caching and nested result mapping ie. In mapperxml two resultMap include the same content or one resultMap include other resultMap. In mapperxml two resultMap include the same content or one resultMap include other resultMap.
