We need to produce an article around 1500+ characters? Actually must be 1500字 (Chinese characters) meaning words? They said "字数要求：必须写满1500字，不能少于1050字！" So need at least 1500 Chinese characters, not words. But they ask "直接输出正文，不要标题". So just the article body, no title.

Structure: 6-8 natural paragraphs, each 150-250 characters (Chinese characters). So total characters approx 6150=900 up to 8250=2000. But they also require at least 1500 characters overall, cannot be less than 1050. So we need to produce about 1500-1800 characters. Each paragraph 150-250 characters. Let's aim for 7 paragraphs of about 215 characters each => ~1505 characters. Good.

We need natural, conversational tone, like talking to friends. Avoid AI clichés. Use specific details, case examples.

Paragraphs must be 150-250 Chinese characters inclusive each. Let's count approximate characters.

We'll write 7 paragraphs.

Paragraph 1: intro, hook, addressing title.

Paragraph 2: basics of JSP, what you need, simple code example.

Paragraph 3: setting up environment, IDE, Tomcat.

Paragraph 4: common pitfalls, debugging.

Paragraph 5: building a small project, login system.

Paragraph 6: scaling up, using Maven, DB integration.

Paragraph 7: concluding, reflecting on mastery.

We must ensure each paragraph length 150-250 characters. Let's count roughly.

We'll write paragraphs and then count characters.

Now count characters (including punctuation). Let's count manually.

I'll count characters (including Chinese characters, punctuation). Paragraph 1 length approx:

Let's count characters ignoring spaces. Chinese characters plus punctuation count as characters? Usually punctuation counts as characters too. Let's count roughly.

I'll count characters sequentially:

Wait Chinese: "这篇文章就带你从零到能独立搭建站点，再一步步深入实战技巧，用真实案例让你看到「入门到精通」到底是什么感觉。"

So total ~127 characters. That's too short; need 150-250 per paragraph. Need to expand.

We need each paragraph 150-250 characters. So paragraph 1 must be at least 150 characters. Let's expand paragraph 1 to about 180 characters.

Paragraph 1 expanded:

I'll count sequentially:

33? Wait we already have JSP counted as characters individually; but we treat each character including Latin letters as one. Continue.

Let's just approximate length; likely around 180-200 characters. Let's quickly use rough estimate: It's probably about 190 characters. Might be okay.

But we need each paragraph 150-250 characters. So we can keep this as ~190.

Paragraph 2: talk about basics of JSP, syntax, scriptlet, JSP expression, etc.

"JSP的核心在于让HTML和Java代码共生。你会看到<% %>, <%= %>这样的标签，它们让服务器端的逻辑能直接嵌入页面。比如写一个简单的<% out.println("当前时间："+new java.util.Date()); %>，运行后页面会显示当前时间。别怕这些尖括号，它们只是把Java代码偷偷塞进HTML里，像在聊天时把我想法说出来一样自然。掌握这些基本语法，就等于拿到和服务器对话的钥匙。"

Now count characters. Let's approximate length; likely around 180-200 characters.

Paragraph 3: environment setup, IDE, Tomcat, etc.

"搭建开发环境是第一步，别想着一次性装好所有工具就卡住。先下载个轻量级的IDE，比如Eclipse或者IntelliJ IDEA Community版，配上Apache Tomcat 9，就能在本地跑起JSP。把Tomcat的webapps目录当作你的项目根目录，把编写好的 *.jsp文件放进去，启动服务器，打开浏览器访问 http://localhost:8080/就能看到效果。整个过程就像搭积木，一块一块堆起来，别急，慢慢来。"

Paragraph 4: common pitfalls, debugging, session management.

"在实际项目里，最常踩的坑往往是SESSION的管理。很多人写完代
