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 4 预览版深度解析：虚拟线程优先架构的全面变革

Deep Dive into Spring Boot 4 Preview: Comprehensive Shift to Virtual Thread-First Architecture

| iDev Tech | 2026-07-10T18:49:44

Spring Boot 4 首个预览版发布，引入虚拟线程优先架构、声明式 HTTP 客户端增强、GraalVM 原生镜像零配置支持和全新的结构化并发模型。本文深度解析关键新特性及迁移策略。

Spring Boot 4's first preview introduces virtual thread-first architecture, enhanced declarative HTTP clients, zero-config GraalVM native image support, and a new structured concurrency model. This article provides a deep dive into key features and migration strategies.

Spring Boot 4：拥抱虚拟线程的新时代2026年9月，Spring 团队发布了 Spring Boot 4.0 的首个里程碑预览版（M1）。这是自 Spring Boot 3.0 以来最大的架构升级，核心变化是全面转向虚拟线程优先（Virtual Thread-First）架构。虚拟线程优先架构Spring Boot 4 默认使用 Project Loom 的虚拟线程作为请求处理线程。传统的 Tomcat 线程池配置将被标记为 @Deprecated。新的执行模型意味着每个 HTTP 请求都运行在轻量级虚拟线程上，消除了线程池大小瓶颈。在基准测试中，相同硬件上的并发处理能力提升了约 8 倍。结构化并发 API引入 @Scoped 注解，自动管理任务组的生命周期新的 TaskScope API 替代 CompletableFuture 复杂链式调用异常传播自动追踪到父任务上下文，调试体验大幅提升与 Spring Security 上下文无缝集成，虚拟线程间自动传播认证信息GraalVM 原生镜像零配置Spring Boot 4 终于实现了原生编译的零配置目标。通过新的编译时元数据生成器，绝大多数 Spring 应用无需手动编写 reflect-config.json 即可成功编译为原生镜像。启动时间从传统 JVM 的2-5秒缩短到50-200毫秒。迁移建议从 Spring Boot 3.x 迁移需注意：ThreadLocal 使用需改为 ScopedValue；自定义线程池需审查兼容性；第三方库需确认虚拟线程支持状态。Spring 团队承诺提供自动化迁移扫描工具。

Spring Boot 4: Embracing the Virtual Thread EraIn September 2026, the Spring team released the first milestone preview (M1) of Spring Boot 4.0. This represents the most significant architectural upgrade since Spring Boot 3.0, with the core change being a comprehensive shift to a virtual thread-first architecture.Virtual Thread-First ArchitectureSpring Boot 4 defaults to using Project Loom's virtual threads for request processing. Traditional Tomcat thread pool configurations are marked @Deprecated. The new execution model means each HTTP request runs on a lightweight virtual thread, eliminating thread pool size bottlenecks. Benchmarks show approximately 8x improvement in concurrent processing capacity on identical hardware.Structured Concurrency APIIntroduction of @Scoped annotation for automatic task group lifecycle managementNew TaskScope API replaces complex CompletableFuture chain callsException propagation automatically traced to parent task context, dramatically improving debuggingSeamless integration with Spring Security context, automatically propagating authentication across virtual threadsZero-Config GraalVM Native ImagesSpring Boot 4 finally achieves zero-configuration native compilation. Through a new compile-time metadata generator, the vast majority of Spring applications can be compiled to native images without manually writing reflect-config.json. Startup time drops from 2-5 seconds on traditional JVM to 50-200 milliseconds.Migration RecommendationsMigrating from Spring Boot 3.x requires attention to: replacing ThreadLocal with ScopedValue; reviewing custom thread pool compatibility; confirming third-party library virtual thread support. The Spring team promises an automated migration scanning tool.
