Optimizing SpringBoot Startup Time: Reducing Bean Scanning and Initialization Overhead

This article explains how a SpringBoot service that originally took 6‑7 minutes to start was trimmed to about 40 seconds by analysing the run‑listener phases, pinpointing costly bean‑scanning and post‑processor steps, and applying JavaConfig‑based selective component registration and cache auto‑configuration adjustments.

Optimizing SpringBoot Startup Time: Diagnosing Bean Scanning and Initialization Bottlenecks

This article explains how to identify and resolve the severe startup latency of a SpringBoot service by analyzing the SpringApplicationRunListener and BeanPostProcessor stages, narrowing scan packages, manually registering beans with JavaConfig, and handling cache auto‑configuration to reduce launch time from minutes to seconds.
