  1. Definition of mapping file: The mapper file in MyBatis is used to define the mapping relationship between SQL statements and Java methods, allowing for the separation of data operations and code.<\/li>\n
  2. Dynamic SQL support: MyBatis mapper files allow for the writing of dynamic SQL statements, enabling the assembly of SQL statements based on conditions, which enhances the flexibility and maintainability of SQL statements.<\/li>\n
  3. Parameter mapping: Mapper files support mapping parameters from Java methods to SQL statements, allowing direct use of Java method parameters in SQL statements, simplifying the writing of SQL statements.<\/li>\n
  4. Result mapping: The mapper file supports mapping the results of the SQL query to Java objects, allowing the query results to be directly encapsulated into Java objects, thus simplifying the process of handling and converting data.<\/li>\n
  5. Plugin support: MyBatis mapper files are able to utilize plugins, allowing for the extension of functionalities within the mapper files to achieve more customization options.<\/li>\n
  6. Easy to maintain: separating SQL statements from Java code makes it easier to maintain mapper files, allowing for modifications to SQL statements and Java code as needed without affecting other parts of the code.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
