1. **Analyze the Request:** * **Goal:** Adjust the previous draft to be between 500 and 800 Chinese characters (excluding punctuation and English). * **Problem:** Previous draft was 504 characters, which is below the 500-800 range. * **Solution:** Add content regarding learning order, prerequisites, learning outcomes, and material usage. Avoid padding, repetition, and empty talk. Do not exceed 800 characters. * **Constraints:** Output only HTML fragment (`
`, `
`, `
`, `
`). No `/`. No zip/mp4 filenames. No cliches. No AI self-introduction. Simplified Chinese. Specific structure (2-3 subheadings, each with a clear paragraph). Include specific points (problem solved, suitable background, suggested sections, independent capabilities, material usage). 2. **Review Previous Draft:** * *Subheading 1:* 这门课解决的核心问题是：帮助开发者从零搭建企业级 Java 应用框架，掌握控制反转（IoC）与面向切面编程（AOP）两大支柱，从而写出高内聚、易测试、可维护的工程代码。适合具备 Java 基础、已了解 Servlet 与 JSP 的开发者。如果你正在从单体应用向微服务架构演进，或者需要在项目中实现依赖解耦与横切关注点，这门课提供的源码与实战案例可以直接对照实践，而非空看理论。 (228 chars) * *Subheading 2:* 建议先看 001 概述与 003 包结构简介这两块。前者建立全局认知，后者理清 Spring 的目录组织逻辑与依赖注入原理。学完本课程，你能独立完成 Spring 核心模块的工程搭建，熟练配置 IoC 容器实现对象的生命周期管理，并运用 AOP 技术处理日志、事务等横切关注点。在测试运维领域，你还能基于 Spring 框架设计自动化测试用例与接口集成，将源码中的组件规范转化为可落地的工程实践。 (193 chars) * *Subheading 3:* 资料包以“源码先行”为原则组织，第 000 节提供完整的项目骨架与初始代码，后续各节则通过环境搭建、IoC 配置等实战步骤逐步推进。建议读者在观看视频时，同步解压并运行提供的示例项目，在“环境搭建”与“将对象配置到 IoC 容器”这两段关键代码中动手修改与试错。通过边看源码、边配置、边验证的闭环，将 Spring 的包结构与依赖注入机制真正内化为可复用的工程模块。 (176 chars) * *Total:* ~597 characters. Wait, the prompt said "上一稿有 504 个汉字，不合格" (Previous draft had 504 Chinese characters, unqualified). Let me recount strictly the Chinese characters (excluding punctuation and English). * S1: 这门课解决的核心问题是帮助开发者从零搭建企业级Java应用框架掌握控制反转IoC与面向切面编程AOP两大支柱从而写出高内聚易测试可维护的工程代码适合具备Java基础已了解Servlet与JSP的开发者如果你正在从单体应用向微服务架构演进或者需要在项目中实现依赖解耦与横切关注点这门课提供的源码与实战案例可以直接对照实践而非空看理论 (153 chars) * S2: 建议先看概述与包结构简介这两块前者建立全局认知后者理清Spring的目录组织逻辑与依赖注入原理学完本课程你能独立完成Spring核心模块的工程搭建熟练配置IoC容器实现对象的生命周期管理并运用AOP技术处理日志事务等横切关注点在测试运维领域你还能基于Spring框架设计自动化测试用例与接口集成将源码中的组件规范转化为可落地的工程实践 (143 chars) * S3: 资料包以源码先行为原则组织第000节提供完整的项目骨架与初始代码后续各节则通过环境搭建IoC配置等实战步骤逐步推进建议读者在观看视频时同步解压并运行提供的示例项目在环境搭建与将对象配置到IoC容器这两段关键代码中动手修改与试错通过边看源码边配置边验证的闭环将Spring的包结构与依赖注入机制真正内化为可复用的工程模块 (143 chars) * Total strict Chinese chars: 153 + 143 + 143 = 439. Wait, the prompt said 504. Maybe my counting method is slightly off, or the prompt's count included some. Regardless, I need to *increase* the character count to at least 500, aiming for ~600-700 to be safe, while adding the requested elements (learning order, prerequisites, learning outcomes, material usage). 3. **Drafting - Expansion Strategy:** * Expand Subheading 1 (Problem & Prerequisites): Add more detail on the learning path/order. Mention starting from basic Spring concepts, moving to IoC/AOP, and finally connecting to Testing/Ops. * Expand Subheading 2 (Suggested Sections & Outcomes): Elaborate on the independent capabilities. Mention building Spring Boot projects, handling dependencies, and writing integration tests. * Expand Subheading 3 (Materials & Practice): Detail how to use the source code. Mention the
