1. **Analyze the Request:** * **Role:** Course editor for GetFromCode. * **Target Audience:** Developers needing source code, tutorials, and actionable engineering references. * **Tone:** Engineering-oriented, structural, reuse-focused, no marketing fluff. * **Angle:** Tech stack, project structure, reusable modules, learning path (comparing to practical use, not just watching). * **Hard Requirements:** * Only write a guide/intro, don't list full file directories, don't list zip/mp4 filenames. * No cliches: "Course recommends", "Skills harvest", "Employment development", "Industry experts carefully crafted", "Complete learning path from beginner to advanced". * Don't claim to be AI, don't mention other site names. * Simplified Chinese. * Output HTML fragment using `
`, `
`, `
`, `
`. No ``/``. * Length: 500-800 Chinese characters (excluding punctuation and English). No padding. * Structure: 2-3 subheadings, each a clear paragraph. * Must include: Problem solved, suitable foundation, suggested first sections, independent capabilities after learning, how materials support practice. * Don't repeat the full course title verbatim. Be specific to the topic (Activiti5 + OA). * Filter out non-IT prefixes if combining titles (not strictly needed here, but keep focus on IT). * Use clues only to understand the topic (Activiti5 workflow + enterprise OA). Don't copy filenames like `21到35节.rar`. 2. **Deconstruct the Course Content:** * *Topic:* Activiti5 workflow + Enterprise Collaborative OA system. * *Tech Stack:* Activiti5, Spring data JPA, Spring Boot/Maven (implied by typical Activiti5 projects), database design, framework setup. * *Modules:* Org structure (departments, users), auth (login), pagination, workflow integration. * *Structure:* 1-20 (Intro, DB design, framework, login, org management, pagination), 21-35 (Workflow core, task handling, etc.), 36-51 (Advanced OA features, integration). 3. **Drafting - Section by Section:** * **Subheading 1: Problem Solved & Foundation** * *Idea:* Why build this? It solves the gap between workflow engine and daily OA tasks. What's the prerequisite? Needs basic Java, Spring, and DB knowledge. * *Drafting (Mental):* 这门课解决的是企业级应用中流程审批与日常办公脱节的问题。很多开发者会用到流程引擎，但不会把它集成到完整的OA业务流里。适合有一定Java后端基础，了解Spring生态和数据库设计的开发者。 * **Subheading 2: Suggested First Sections & Independent Capabilities** * *Idea:* Start with the foundation (DB, framework, login). What can you do after? Build a complete OA system with approvals, org management, etc. * *Drafting (Mental):* 建议先看数据库设计、框架搭建和用户登录这三块，打好地基。学完能独立搭建一个具备部门管理、用户增删查改、登录鉴权以及基于Activiti5的流程审批的协同办公系统。 * **Subheading 3: Materials & Practice** * *Idea:* How to use the materials? Code + Docs + PPT. How does it help practice? Step-by-step project building, reusable modules. * *Drafting (Mental):* 资料包包含完整的项目代码、配套文档与PPT，配合课程分阶段讲解，边学边改。从表结构设计到工作流节点配置，每个模块都拆分为可复用的工程组件，开发者可以直接对照代码修改现有项目，快速落地审批流与业务流的结合。 4. **Refining and Formatting (HTML & Character Count):** * *Subheading 1:*
