Summary

Implemented generic type support for therootInterface property in MyBatis Generator, addressing issue#1346.

Changes Made:

1. Added utility method inAbstractJavaClientGenerator:

   • processRootInterfaceWithGenerics(): Processes the rootInterface string and replaces generic placeholders (e.g.,<T>,<T extends Entity>) with the actual record type from the introspected table

   • isGenericPlaceholder(): Detects if the generic content is a placeholder (single uppercase letter like T, E, K, V, optionally with "extends" or "super" clause)

2. Updated all three Java client generators:

   • JavaMapperGenerator

   • SimpleJavaClientGenerator

   • DynamicSqlMapperGenerator

3. Updated documentation:

   • Added "Generic Type Support" section to bothjavaClientGenerator.xhtml andtable.xhtml documentation files

4. How It Works:

   • If you specifyrootInterface="BaseMapper<T>", it becomesBaseMapper<com.example.User> for a User table
   • If you specifyrootInterface="BaseMapper<T extends Entity>", it becomesBaseMapper<com.example.User>
   • If you specifyrootInterface="BaseMapper" (no generics), it remains unchanged (backward compatible)
   • If you specifyrootInterface="BaseMapper<com.example.User>" (fully qualified), it's used as-is

Example Usage:

<javaClientGeneratortargetPackage="com.example.mapper"targetProject="src/main/java"type="XMLMAPPER">    <propertyname="rootInterface"value="com.mycompany.BaseMapper&lt;T&gt;"/></javaClientGenerator>

This will generate mapper interfaces like:

publicinterfaceUserMapperextendsBaseMapper<User> {// ...}

Resolves

Closes#1346 - Feature Request : Generics support in javaClientGenerator rootInterface

The implementation is backward compatible and passes all linter checks.
Ready for testing and review.
