What is the purpose of TypeAliasRegistry in Mybatis?

TypeAliasRegistry in MyBatis is a class that manages aliases. Its purpose is to map Java types or class names to short aliases for easier use in MyBatis configuration files.

The TypeAliasRegistry allows you to register aliases by calling its registerAlias method. After registering an alias, we can use this alias in the Mybatis configuration file instead of the full Java type or class name.

Using aliases can make MyBatis configuration files cleaner and reduce duplicate code. Additionally, if our project utilizes many custom Java types, using aliases can make the code more readable and easier to maintain.

In summary, the purpose of the TypeAliasRegistry is to manage and provide alias functionality, making MyBatis configuration files more concise and readable.
