Exception Handler For MFE_Refactoring Project's Rest Services

Abstract

• The exception handler structure of micro service projects need to be error-descriptive.

• Users shouldn't see application errors or application exceptions.

• Let's think of a scenario: A process needs to go through 4 micro-services, respectively. When it encounters an error in the 3rd micro service or throws an exception, this error needs to be moved backwards properly, and its important to detect which micro-services has an error and when.

• For this reason, Exception Output object includes timestamp, API, error-code, and whoAmI variables. Variables use front-end (presentation) layer.

• A pop-up similar to the one below can be used.
