# Masking

Masking is now applied by the MessageConverter when a Controller returns a response, rather than by the DAO-to-DBMS layer. The former MyBatis interceptor `<plugin interceptor="com.x2bee.common.base.masking.MybatisMaskingInterceptor"/>` has been removed.

Use `@MaskString(type = MaskingType.NAME_EN)` on response DTO fields. For project-specific behavior, extend `MaskingUtils`, override `getValue`, register the custom bean, and configure `masking.utils.bean` in `application.yml`.
