Java Error: Not Authorized to Invoke 'save' Method in GoodsTypeController

This error message indicates that the 'save' method in the 'GoodsTypeController' class is not accessible or authorized to be invoked.

Possible reasons for this error could be:

1. The method is declared as private or protected, and therefore cannot be accessed from outside the class.
2. The method is declared with restricted access modifiers, such as 'default' access or 'protected' access, and is being accessed from a different package or class that does not have the required access level.
3. The method is part of a different module or library that is not imported or included in the current project setup.

To resolve this issue, you need to ensure that the 'save' method in the 'GoodsTypeController' class has the appropriate access modifiers (e.g., public), and that it is accessible from the class or package where it is being invoked. Additionally, make sure that all required dependencies or modules are properly included and imported in your project.
