Avoid Hidden Performance Landmines: 7 Common Spring Boot Production Pitfalls

The article identifies seven common performance killers in Spring Boot production—N+1 queries, unbounded thread pools, excessive logging, oversized response bodies, missing indexes, synchronous external API calls, and serial API invocations—and provides concrete code‑level solutions such as eager fetching, custom thread pools, lazy logging, DTOs, index creation, timeout configuration, and CompletableFuture parallelism.

Spring Boot @Async in Production: From Default Pitfalls to Thread Pool Governance

This article details Spring Boot @Async production pitfalls including unbounded thread creation, context loss, swallowed exceptions, and OOM risks, then provides concrete solutions: explicit ThreadPoolTaskExecutor configuration with bounded queues, TaskDecorator for MDC/TraceId/SecurityContext propagation, global exception handling, CompletableFuture orchestration without blocking, and monitoring with dynamic tuning to prevent thread leaks and OOM.

Mastering SpringBoot @Async: Thread‑Pool Configuration, Pitfalls, and Best Practices

The article explains why @Async, the most used async solution in SpringBoot, often causes OOM, missing trace IDs, silent failures, and task avalanches, and then walks through the underlying AOP mechanism, thread‑pool choices, timeout handling, context propagation, transaction interactions, monitoring, and dynamic tuning.

Efficient Large-Scale Data Export in SpringBoot: Parallel EasyExcel to Multiple Files and ZIP Download

The article demonstrates how to avoid blocking SpringBoot services during massive Excel exports by splitting data, using CompletableFuture with a ThreadPoolTaskExecutor to generate multiple Excel files concurrently via EasyExcel, then compressing them into a ZIP for client download, including full code and resource‑cleanup details.

Mastering Spring Boot Thread Pools: From Default Config to Custom Solutions

This article explains how Spring Boot automatically configures a ThreadPoolTaskExecutor for @Async and @Scheduled, shows the default parameters introduced in version 2.1, demonstrates how to inspect and customize them, compares the default executor with SimpleAsyncTaskExecutor, and provides code examples for using @Async, injecting the executor, and defining a custom thread pool to avoid resource‑exhaustion issues.
