Oracle Java 要收費了，我們決定不當冤大頭，全面改用其他免費的JDK/JRE替代方案！

Oracle Java 要收費了，我們決定不當冤大頭，全面改用其他免費的JDK/JRE替代方案。

為了省下每年 3,000 萬的「冤枉錢」，軟體JDK/JRE要大換血了！

1. 發生了什麼事？（為什麼要換？）
原本我們用的 Java 軟體（想像成一種電腦必備的引擎），收費方式突然「坐地起價」。

• 以前： 有幾台電腦用，就付幾台的錢（大約 100 萬）。
• 現在： 只要公司有一個員工，就要付一份錢。不管你有沒有用到，Oracle 公司都要收費。
• 結果： 費率從 100 萬暴漲到 3,000 萬！這對銀行來說太不划算。

2. 我們的對策是什麼？
既然這家店變成了「黑店」，我們決定全行集體「換一家店」。
我們會把所有 Oracle 公司的 Java 軟體通通刪除，換成功能一樣，但收費合理、甚至免費的其他合法軟體（例如 IBM 或 Azul 提供的版本）。

3. 這會影響到誰？

• 工程師與相關單位： 必須在期限內動手把舊引擎拆掉，換上新引擎。
• 一般大眾/客戶： 銀行這麼做是為了節省營運成本，把錢花在更有意義的地方。只要換得好，系統運作不會受影響，大家可以放心。

4. 為什麼要這麼急？
因為如果沒換掉又被抓到在使用，會產生法律賠償問題（授權不合法），而且舊的版本如果沒付錢就無法更新，會有被駭客攻擊的風險。

一句話總結：
「因為 Oracle 變太貴，Oracle Java 要收費了，快快全面改用其他好用又免費的JDK/JRE軟體，請大家配合在時間內完成更換，確保系統安全又省錢！」

📢 軟體更換懶人包：告別 Oracle，迎接新 Java！

簡單來說，我們要執行的動作就是：「刪除舊軟體、安裝新替代品、確認設定正確」。

1. 為什麼要選這些軟體？

這三家（Adoptium, Azul, Amazon）都是目前全球最穩定的 Java 引擎。它們就像是「不同品牌的汽油」，雖然廠牌不同，但都能讓你的車（系統）正常跑，而且通通合法且更便宜/免費。

2. 我該選哪一個？（指南建議）

• 一般人首選： Eclipse Adoptium (Temurin)。它是社群公認最穩定的標準。https://adoptium.net/temurin/releases/?version=8
• 需要特殊舊版本： Azul Zulu。如果你的舊系統一定要用 Java 8 或更老版本，選它最穩。Azul Zulu Builds of OpenJDK https://www.azul.com/downloads/
• 雲端或大企業愛用： Amazon Corretto。亞馬遜出品，非常耐操。https://aws.amazon.com/corretto/
• 依照發行版選擇：
  • IBM SDK (Semeru): 若行內已有大量 IBM 中間件（如 WebSphere），此版本相容性最佳。https://www.ibm.com/support/pages/java-sdk-downloads
  • Azul Zulu: 提供商業級支援（Support），且對於舊版 Java (如 Java 6, 7) 的維護支援較廣，適合有遺留系統（Legacy）的單位。Azul Zulu Builds of OpenJDK https://www.azul.com/downloads/
  • Eclipse Temurin (Adoptium): 免費開源的首選，適合無須原廠商業支援的開發環境。https://adoptium.net/temurin/releases/?version=8
• 相容性測試 (UAT)： 要求各單位針對「字型處理」、「加密套件 (JCE)」及「時區資訊」進行重點測試，這些是轉換 JDK 時最常出現微小差異的地方。

3. 具體怎麼換？（三步驟）

要把 Oracle Java 換掉，其實就像「手機換 SIM 卡」或「家電換電池」一樣，只要掌握「移除、安裝、設定」這三個步驟，電腦就能無縫接軌。

以下是針對一般員工或技術人員都適用的白話版三步驟：

---

第一步：卸載 (移除舊的 Oracle Java)

就像要裝新家具前，得先把舊的搬走，避免電腦「打架」。

1. 開啟電腦的 [控制台] > [程式與功能]（或搜尋「新增或移除程式」）。
2. 在清單中尋找所有名稱包含 "Java"、"JDK" 或 "JRE"，且發行者是 "Oracle" 的項目。
3. 按滑鼠右鍵選擇 [解除安裝]。
   • 註：如果有好幾個版本，請通通移除乾淨。

第二步：安裝 (換上新的合法版本)

從銀行推薦的連結中選一個下載（建議優先選 Eclipse Temurin 或 Azul Zulu）。

1. 下載： 點選連結後，選擇適合你作業系統（通常是 Windows x64）的 .msi 檔案下載。
2. 執行： 雙擊下載好的安裝檔，然後一路點「下一步 (Next)」直到完成。
   • 重點：安裝過程中如果看到「Set JAVA_HOME variable」或「Associate .jar」的選項，請確認都有勾選（通常預設會勾）。

第三步：設定與檢查 (確認新引擎已發動)

安裝完後，我們要告訴電腦：「現在改用這台新引擎了」。

1. 檢查環境變數（最關鍵）：
   • 在電腦搜尋列輸入「環境變數」，選擇「編輯系統環境變數」。
   • 點擊 [環境變數] 按鈕，檢查下方的「系統變數」。
   • 確認 JAVA_HOME 這個項目的路徑，已經指向新安裝的資料夾（例如：C:\Program Files\Eclipse Adoptium\...）。
2. 黑視窗驗證：
   • 按下鍵盤 Win + R 鍵，輸入 cmd 按 Enter。
   • 在黑色視窗輸入 java -version 後按 Enter。
   • 只要畫面出現 "OpenJDK"、"Temurin" 或 "Zulu" 字樣，而不是 "Oracle"，就代表你成功了！

---

💡 小提醒：
如果您是幫公司的伺服器更換，建議在執行前先做系統備份 (Snapshot)，並在更換後重新啟動相關的應用程式服務（如 Tomcat 或專屬業務軟體），確認程式能正常讀取到新的 Java 路徑。

4. 注意事項

• 不用擔心不能用： 雖然換了品牌，但底層技術是一樣的，就像從中油換到台塑加油，車子開起來感覺是一樣的。
• JRE 沒了怎麼辦： 以前有個東西叫 JRE，現在通通包含在新的安裝包裡了，只要照著連結下載就沒問題。

Chapter 3: The Blank Space on the Shinkansen

 

Inside the Nozomi Shinkansen carriage, a clean scent of premium leather mingled with the air conditioning filter filled the air . The scenery outside the window was blurring backward at 300 kilometers per hour, towns, farmland, and telephone poles all turning into blurry blocks of color.

Denji sat in the window seat , his body sinking deep into the unreal, soft blue cushions. His mind, like the view outside the window, was in a state of "blank" after a period of high-speed processing.

" Denji-kun , what are you thinking about?"

Makima sat very close, so close that Yodo could feel the faint warmth of her thigh. Today she was wearing a soft, light-colored trench coat, and was elegantly unpacking an exquisite train bento box. The ingredients in the bento box were crystal clear; the salmon roe shimmered like rubies, and the Wagyu beef fat was distributed like a work of art.

"Hehe, it's nothing, Miss Makima!" Denji turned around, revealing his signature toothless, goofy grin. He took the bento box Makima handed him and began to devour it without a care for appearances. "I'm just thinking, this feels like a dream. A trip! And with Miss Makima alone! I must have saved the galaxy in my past life!"

"Really? Then Denji-kun should eat more. You're too thin. If you don't eat enough, you won't be able to protect me properly." Makima took out a lightly scented handkerchief from her bag and gently wiped the sauce off Denji's lips.

At that moment, Denji 's heart pounded; it was the treatment he had always dreamed of. To be needed, to be cared for, to be loved.

But strangely, deep within that intense throbbing, a chilling sensation was quietly spreading. It felt like a tiny, yet hard grain of sand had gotten stuck in a finely tuned gear at full speed. Whenever he felt his most "happiest" moment, that grain of sand would rub against his nerves, reminding him that something was missing.

Denji turned to look out the window, just as they passed an unnamed station platform. For a fleeting moment, an afterimage seemed to appear on his retina: a girl wearing a sleeveless vest, her arms wrapped in bandages, standing alone in the rain. Her lips were moving, as if she were calling his name.

" Denji-kun , let's run away."

These words struck him like a bolt of lightning . Denji 's hand jerked violently , and the salmon roe in the bento box rolled to the ground.

" Denji-kun ?" Makima's voice was still gentle, but her pale yellow eyes were like bottomless whirlpools, fixed on him.

"Ah... I 'm sorry, Miss Makima, my hand slipped!" Denji hurriedly bent down to pick it up, his heart pounding so hard it felt like it was going to jump out of his throat.

He began to feel fear. Not fear of Makima, but fear of the ever-emerging memory. Who was that girl? Why did thinking of her cause a tearing pain in his chest? "Lei... " His tongue instinctively tried to utter that syllable, but the moment the name was about to take shape, a sharp pain shot through his cerebral cortex, as if a thin steel needle had pierced the core of his consciousness.

" Denji-kun , are you thinking about the scenery you saw at the station just now?" Makima reached out, her cold fingers gently smoothing his messy blond hair. "Those meaningless noises will only interfere with your happiness . Just look at me, just think... I will give you everything you want."

Her voice carried an almost magical, hypnotic frequency. Yodo looked up at her, her overlapping pupils widening before him, gradually filling his entire field of vision. In those eyes, he couldn't see the scenery outside the window, the girl in the rain , or even the past version of himself scavenging for food in the garbage dump.

"No ... meaningless noise," Denji muttered to himself, his eyes gradually becoming unfocused.

The grain of sand in his heart was ground down by Makima's gentleness, turning into powder and eventually disappearing. That " discomfort " was forcibly flattened, replaced by a false sense of peace, like being immersed in warm water.

"Miss Makima, I'm full." Yodo put down his bento box and, like a docile cat, rested his head on Makima's shoulder. "I'm so sleepy ."

" If you're sleepy , go to sleep, Denji-kun . When you wake up, we'll have reached the finish line."

Makima looked out the window, a faint smile playing on her lips. On the reflective glass, Denji 's face appeared blurry, as if his soul were slowly dissipating in the wind with the high-speed movement of the Shinkansen.

As the Shinkansen swayed smoothly, Denji fell into a deep sleep . In his dream, he saw a blooming flower, but just as he reached out to catch it, the flower turned into a burning flame, leaving not even ashes.

Beside him, the red- haired ruler was quietly guarding this murder, woven by her own hands, under the gaze of someone looking at a beloved collectible, a murder she herself had orchestrated called "happiness."

Chapter Two: Dead Fish Eyes in the Dark and the Hunter

 

At the street corner outside the café, sunlight was cut into sharp fragments by dilapidated advertising billboards. Anbian stood in the shadows, his dark green trench coat bearing the lingering smell of gunpowder and alcohol. His bloodshot, lifeless eyes, like those of a dead fish, were fixed on the red-haired woman inside the café through the water-stained , fingerprint-strewn glass window.

He slowly pulled the silver flask from his pocket , his fingers trembling slightly from the alcohol poisoning. With a "click," the spicy and cheap whiskey slid down his throat, but it did nothing to suppress the nagging unease in his stomach.

"Tsk, what a hopeless idiot." The Kishibe muttered a curse under his breath, exhaling a cloud of murky white mist.

From the Kishibe, Makima's silhouette appeared elegant, slender, and harmless, like an ordinary woman enjoying afternoon tea with her first love. But to the Kishibe, it wasn't a human silhouette at all. He'd seen it far too many times — that precise angle of her slightly tilted head , that deliberately softened tone with a manipulative frequency, and those yellow, circular eyes that could completely control the subject's cognition, like a swirling black hole.

That was a hunt.

He saw that just a second ago , Denji looked like a lost dog , huddled in a chair, his face filled with the lingering image of the girl named " Reige ". However, the instant Makima's fingers touched the back of Denji 's hand, Kishibe counted to three in his mind.

Three, two, one.

Denji felt as if he 'd been struck by a 10,000-volt high-voltage current; his lifeless pupils were instantly filled with a chilling excitement. It was an expression of "forgetfulness." In his decades-long career as a hunter on the Kishibe, he had seen countless humans manipulated by demons, but no demon's power could so elegantly and completely bleach a person's soul like Makima.

He knew better than anyone how deep the wound that girl named Reise had left in Denji 's heart. It wasn't just an ordinary heartbreak; it was the first time in Denji 's garbage-dump-like life that he experienced the hope of being "chosen" and "escaping." It was his awakening as a "human being."

But in front of Makima, that profound pain that was enough to be remembered for a lifetime was like a thin layer of snow that couldn't even last a second under the scorching sun, quickly evaporating without a trace.

"That kid, he's even forgotten why he was crying." Anbian took another swig of wine, the alcohol burning his esophagus and reminding him of his long- dead comrades.

Then, Denji burst out of the coffee shop . He nearly knocked over passersby at the entrance, a pure, almost chilling, smile on his face. He sprinted past like a hound finally given a command to chase a ball, completely unaware that a pair of eyes filled with pity and disgust were watching him from the shadows.

A few seconds later, Makima gracefully walked out of the shop. She stopped by the roadside, seemingly enjoying the warmth of the post-rain sunshine. Then, as if she had accurately predicted her hiding place on the bank, she slightly turned her head, her gaze sweeping precisely and sharply towards the narrow alley.

That was a provocation. Even from a distance, Kanbe felt as if a cold, long needle pierced his brain. He could hear Makima's calm yet haughty voice echoing in his mind: "Mr. Kanbe, peeping at someone on a date is not gentlemanly behavior. Besides, this dog is now entirely mine."

Anbian gripped the wine jug tightly, his knuckles turning white from the force. He knew that this so-called "journey" was nothing more than a cage prepared by Makima to completely sever Dianzhi 's humanity and strip him of his last connection to reality.

" Reige ... " On the Kishibe, looking in the direction where Denji disappeared, there were only a few cherry blossom petals left, knocked down by the rain and rotting in the sewage.

In the boy's eyes, the whole world now consisted only of Makima. He even forgot that he had been crying for another girl just minutes before. This "forgetfulness" was not due to recovery, but rather because his brain's defense mechanisms, his memory storage, and his definition of happiness had all been completely taken over by that woman.

"Madmen, dead men, and fools who've been completely fooled." On the Kishibe, he put away his wine jug, pulled up the collar of his trench coat, and turned to walk into the bottomless alley. His figure gradually blurred, only his hoarse mutterings lingered in the wind:

"This movie is so awful it makes you want to vomit . But I have to keep watching until the last character leaves the theater."
