Java 8 Update 20 Missing security options
提问by Grim Reaper
I have Java 8 update 20 and I just made my first applet, but when I try to run it in the browser it says that my security settings have blocked it! After I go into my java settings and go in the security tab all I see it:
我有 Java 8 更新 20 并且我刚刚制作了我的第一个小程序，但是当我尝试在浏览器中运行它时，它说我的安全设置已阻止它！在我进入我的 Java 设置并进入安全选项卡后，我看到了它：
Enable Java content in the browser (It is a checkbox) Security level for applications not on the Exception site list Very high (RADIO BUTTON) High (RADIO BUTTON)
在浏览器中启用 Java 内容（这是一个复选框） 不在例外站点列表中的应用程序的安全级别 非常高（RADIO BUTTON） 高（RADIO BUTTON）
And then I have my exception site list... I am missing the Medium radio button? I can't run my applet without the medium option! I have tried adding my site to the exceptions list but it didn't work... I have deinstalled the previous version of java which was Java 8 update 11. What's the problem??? Thanks!
然后我有我的例外站点列表...我缺少中单选按钮？如果没有中等选项，我将无法运行我的小程序！我曾尝试将我的网站添加到例外列表中，但它不起作用...我已经卸载了先前版本的 Java，即 Java 8 更新 11。有什么问题？？？谢谢！

Correct. You are missing the Medium radio button now. To quote the 8u20 release notes
正确的。您现在缺少“中”单选按钮。引用8u20 发行说明
Java Control Panel Changes
The Update tab in the Java Control Panel now enables the users to automatically update 64-bit JREs (in addition to 32-bit versions) that are installed on their system.
The
Mediumsecurity level has been removed. Now onlyHighandVery Highlevels are available.
Java 控制面板更改
Java 控制面板中的更新选项卡现在使用户能够自动更新安装在其系统上的 64 位 JRE（除了 32 位版本）。
将
Medium安全级别已被删除。现在只有High和Very High级别可用。
You can develop with an applet viewer; you'll need to sign your code for security reasons.
您可以使用小程序查看器进行开发；出于安全原因，您需要对代码进行签名。
