What is the method for configuring MyBatis type handler…

MyBatis offers two methods for configuring TypeHandlers: through annotations or XML configurations.

1. Annotation Method:
   Add the @TypeHandler annotation to the field or parameter that requires a TypeHandler, and specify a TypeHandler class. For example:

@TypeHandler(MyTypeHandler.class)
private MyEnum myEnum;

MyTypeHandler is a custom TypeHandler class used for handling specific data type conversion logic.

1. Tags are used to configure TypeHandlers. For example:

<typeHandlers>
    <typeHandler handler="com.example.MyTypeHandler"/>
</typeHandlers>

In this case, com.example.MyTypeHandler is the fully qualified name of a custom TypeHandler class.

Regardless of the method used, it is necessary to implement the TypeHandler interface or extend the TypeReference class, and implement its methods to complete the data type conversion logic.
