[MyBatis-Plus] False positive warning on method override in ServiceImpl class

[zhikuigao]

I’m encountering a false positive warning in my MyBatis-Plus ServiceImpl class. The warning appears on the page method override, even though the implementation is correct.

Code example:

@Override
public Page<DeviceCategory> page(QueryPage page, DeviceCategoryQueryReq query) {
    return this.page(page, this.combineQuery(query));
}

The class structure:

• My service interface extends IService<T>
• My implementation class extends BaseDAO<Mapper, Entity> and implements the service interface
• The page method is correctly implemented according to the interface contract

The warning suggests there’s an issue with the method override, but:

1. The method signature matches the interface
2. The generic types are correct
3. The code works correctly at runtime
4. This is a common pattern in MyBatis-Plus applications

Has anyone else encountered this issue? Is there a way to properly suppress this warning without using @SuppressWarnings?

Environment:

• MyBatis-Plus 3.5.2
• Java 8
• Cursor IDE
