下載JDK不需要Oracle賬戶

Oracle官網找到需要下載的JDK版本

如：https://www.oracle.com/cn/java/technologies/javase/javase-jdk8-downloads.html#license-lightbox

在相應的下載鏈接進入下載界面：

同意協議，點擊下載，然后他會彈出需要登錄的彈窗，不要關閉，看瀏覽器地址欄的鏈接地址：

https://www.oracle.com/webapps/redirect/signon?nexturl=https://download.oracle.com/otn/java/jdk/8u281-b09/89d678f2be164786b292527658ca1605/jdk-8u281-linux-x64.tar.gz

很顯然我們可以找到下載鏈接：

https://download.oracle.com/otn/java/jdk/8u281-b09/89d678f2be164786b292527658ca1605/jdk-8u281-linux-x64.tar.gz

然后把下載鏈接復制到新的地址欄，同時修改otn為otn-pub，回車即可開始下載
