We need to produce a 1500+ character article? Wait they say "字数要求：必须写满1500字，不能少于1050字！". So must be at least 1500 Chinese characters? Or words? Likely characters. They also say each paragraph 150-250 words? Wait they say "每段150-250字". That's words? In Chinese, "字" usually means characters, but they also say 1500字 overall. So each paragraph 150-250 characters, and 6-8 paragraphs. That yields total about 900-2000 characters, but they require at least 1500 characters total. So we need 6-8 paragraphs each 150-250 characters, and total at least 1500 characters. So we need maybe 7 paragraphs of ~215 characters each = 1505 characters. That satisfies.
We must not include the title. Just the body. Must be natural, conversational, no AI style. Must not use forbidden words. Must avoid opening with "随着..." etc. So start directly into topic, referencing title maybe indirectly. Must have 6-8 paragraphs, each 150-250 characters. Let's aim for 7 paragraphs of about 220 characters each. That's about 1540 characters total. Let's draft.
Paragraph 1: talk about why lightweight embedded DB is needed, HyperSQL mention.
Paragraph 2: features of HyperSQL, ease of use, no server.
Paragraph 3: performance characteristics, transaction handling.
Paragraph 4: integration examples in Java, Spring Boot.
Paragraph 5: migration from other DBs, compatibility.
Paragraph 6: troubleshooting common issues.
Paragraph 7: conclusion tying back to title.
We need to ensure each paragraph 150-250 characters. Count characters roughly. Let's craft each paragraph about 220 characters.
I'll write paragraphs separated by blank lines.
Now count approximate characters. Let's draft paragraph 1:
"其实，在开发一个小型应用时，往往不想去折腾庞大的数据库服务器。这时候，找一款直接嵌入到程序里的轻量数据库就显得特别重要，而HyperSQL数据库正是这种场景的理想选择。它的核心优势在于不需要额外进程，直接以jar包或源码方式运行，省去很多部署麻烦。"
Let's count characters: I'll count manually (including punctuation).
Paragraph 1 text (including punctuation and spaces? Probably characters are counted including spaces? We'll approximate). Let's count characters without spaces? Chinese characters count each Chinese character, punctuation also counts? Usually "字" counts Chinese characters, but we can approximate length. Let's count characters manually:
"其实，在开发一个小型应用时，往往不想去折腾庞大的数据库服务器。这时候，找一款直接嵌入到程序里的轻量数据库就显得特别重要，而HyperSQL数据库正是这种场景的理想选择。它的核心优势在于不需要额外进程，直接以jar包或源码方式运行，省去很多部署麻烦。"
Let's count Chinese characters (including letters? HyperSQL includes Latin letters, but they count as characters too). Let's count roughly:

Actually we counted up to 121 characters? Let's recount more precisely: I think we overshoot. Anyway it's maybe around 150 characters? Let's approximate it's about 150 characters. But we need each paragraph 150-250 characters. So we need to be longer. Let's add more detail.
Better to write full paragraphs of about 200-220 characters.
I'll craft each paragraph with ~220 characters.
Paragraph 1: maybe 220 characters.
Let's write a longer paragraph:
"其实，在开发一个小型应用时，往往不想去折腾庞大的数据库服务器。这时候，找一款直接嵌入到程序里的轻量数据库就显得特别重要，而HyperSQL数据库正是这种场景的理想选择。它的核心优势在于不需要额外进程，直接以jar包或源码方式运行，省去很多部署麻烦，让你可以把注意力放在业务逻辑上，而不是数据库管理。"
Now count characters: Let's count roughly.

Actually "jar" is three letters, count each: j102 a103 r104, or105 source106? Let's continue: "或"105? Wait we already counted "或" as 105? Let's recount after "直接以". Actually we wrote "直接以jar包或源码方式运行，省去很多部署麻烦，让你可以把注意力放在业务逻辑上，而不是数据库管理。" Let's continue counting.
继续: "直接以" we already counted up to "直"? Actually we counted up to "直" as 99? Let's just continue after "直接以". We'll count from there.
我们已经到 "直接以" characters: "直" (99), "接" (100), "以" (101). Then "jar包" adds j102 a103 r104 包105. Then "或"106, "源码"107? Actually "源"107, "码"108, "方式" maybe "方"109, "式"110. Then "运行" "运"111, "行"112, "，"113, "省"114, "去"115, "很"116, "多"117, "部"118, "署"119, "麻"120, "烦"121, "，"122, "让"123, "你"124, "可"125, "以"126, "把"127, "注"128, "意"129, "力"130, "放"131, "在"132, "业"133, "务"134, "逻"135, "辑"136, "上"137, "，"138, "而"139, "且"140, "不"141, "要"142, "数"143, "据"144, "库"145, "管"146, "理"147, "。"148
So total maybe around 148 characters. That's less than 150. Need each paragraph 150-250 characters. So we need to add more content to reach ~170-180 characters.
We can add more sentences about benefits.
Let's expand paragraph 1 to about 180 characters.
Add: "而且，它兼容标准SQL，支持事务，能够在不改动现有代码的情况下平滑切换。" That's extra characters.
Add that sentence after previous.
Now count extra characters: "而且，它兼容标准SQL，支持事务，能够在不改动现有代码的情况下平滑切换。" Let's count:
且1，2，3，... Actually let's count: "而且"2, "，"1, "它"1, "兼"1, "容"1, "标"1, "准"1, "
