I'm not technical. Can I work with iDev?

Absolutely. Most of our clients are non-technical. Just tell us what you want the end result to look like — we handle all the technical details.

How much does it cost to hire iDev?

We quote individually based on project scope and complexity. Initial consultation is completely free — we give you a clear quote after understanding your needs. No fit, no charge.

How big is the iDev team?

A few core members, each capable of delivering full-stack independently. We flexibly assign people based on project scale and can run multiple projects simultaneously.

What happens after project delivery?

We provide complete code and documentation at handover. For ongoing feature development or maintenance, we offer monthly or per-project arrangements. Most clients choose long-term collaboration.

What if I'm not satisfied with the project midway?

We confirm with you at every stage before moving forward. If the direction is off, we adjust immediately. If it truly can't continue, completed work is settled normally and all code is yours.

我完全不懂技术，能合作吗？

当然可以。我们的大部分客户都不是技术背景。你只需要告诉我们你想要什么效果，技术实现的事情完全由我们来处理。

费用大概是多少？

根据项目复杂度和功能范围单独报价。初次沟通完全免费，我们会在了解需求后给出明确报价，合适再开始，不合适不收费。

团队有几个人？

核心团队几个人，都是能独立交付的全栈开发者。根据项目规模灵活安排人手，可以同时推进多个项目，不用等排期。

项目做完以后怎么维护？

交付时会提供完整的代码和文档。后续如果需要功能迭代或维护，可以按月或按次合作。大部分客户选择了长期合作。

做到一半不满意怎么办？

每个阶段交付前都会和你确认。如果方向不对，我们及时调整。如果实在无法继续，已完成的部分正常结算，代码归你。

Spring Boot 3.3中虚拟线程的正确使用姿势

Alex Chen | 2026-08-26T18:48:26 | Java, Spring Boot

虚拟线程是Java 21的重大特性，Spring Boot 3.3提供了开箱即用的支持。

## 什么是虚拟线程 Virtual Threads 是 Java 21 引入的轻量级线程。 ## 启用 ```yaml spring: threads: virtual: enabled: true ``` ## 性能对比 | 指标 | 平台线程 | 虚拟线程 | |------|---------|--------| | 并发 | 200 | 10,000+ | | P99 | 450ms | 120ms | | 吞吐量 | 1.2k/s | 4.8k/s | ## 陷阱 1. 避免 synchronized，用 ReentrantLock 2. 不要池化虚拟线程 3. ThreadLocal 要谨慎
