I. Introduction

When developing microservices using Spring Boot, it is often necessary to handle system errors and exceptions. In real business scenarios, once a project goes online, unexpected situations inevitably arise during use. At such times, it is essential to enhance the error handling mechanisms at the code level with the framework’s support. Common scenarios include coding errors, database query errors, third-party API invocation errors, and uncaught exceptions. This article will provide a detailed introduction on how to utilize Spring Boot’s exception handling mechanisms more reasonably in microservices development.

II. Spring Boot Exception Overview

2.1 Spring Boot Exception Definitions

In a Spring Boot application, exceptions refer to events that disrupt the normal program flow during execution. Spring Boot provides a robust mechanism for managing and handling these exceptions, ensuring that the application responds in a controlled manner when errors occur and communicates effectively with users.
