The message seems to be out of date. In version 4 that setting exists in two files, and you need to change it in the other one, which is:
该消息似乎已过时。在版本 4 中，该设置存在于两个文件中，您需要在另一个文件中更改它，即：
%APPDATA%\sqldeveloper.0.0.0.0\product.conf
Which you might need to expand to your actual APPDATA, which will be something like C:\Users\cprasad\AppData\Roaming. In that file you will see the SetJavaHomeis currently going to be set to the path to your Java 1.8 location, so change that as you did in the sqldeveloper.conf:
您可能需要将其扩展到您的实际APPDATA，这将类似于C:\Users\cprasad\AppData\Roaming. 在该文件中，您将看到SetJavaHome当前将被设置为您的 Java 1.8 位置的路径，因此请按照您在以下文件中所做的更改sqldeveloper.conf：
SetJavaHome C:\Program Files\Java\jdk1.7.0_60\bin\
If the settig is blank (in both files, I think) then it should prompt you to pick the JDK location when you launch it, if you prefer.
如果 settig 为空白（我认为在两个文件中），那么它应该会提示您在启动它时选择 JDK 位置，如果您愿意的话。

In your SQL Developer Bin Folder find
在您的 SQL Developer Bin 文件夹中找到
\sqldeveloper\bin\sqldeveloper.conf
It should be
它应该是
SetJavaHome \path\to\jdk
You said it was ../../jdkoriginally so you could ultimatey do 1 of two things:
你说它../../jdk最初是这样你最终可以做两件事之一：
SetJavaHome C:\Program Files\Java\jdk1.7.0_60
This is assuming that you have JDK 1.7.60 installed in that directory; you don't want to point it to the binfolder you want the whole JDK folder.
这假设您在该目录中安装了 JDK 1.7.60；您不想将其指向bin您想要整个 JDK 文件夹的文件夹。
OR
或者
The second thing you can do is find the jdkfolder in the sqldeveloper folder for me its sqldeveloper\jdkand copy and paste the contents from C:\Program Files\Java\jdk1.7.0_60. You then have to revert your change to read
您可以做的第二件事是jdk为我在 sqldeveloper 文件夹中找到该文件夹，sqldeveloper\jdk然后从C:\Program Files\Java\jdk1.7.0_60. 然后，您必须恢复更改才能阅读
SetJavaHome ../../jdk
in your sqldeveloper.conf
在你的 sqldeveloper.conf
If all else fails you can always redownload the sqldeveloper that already contains the jdk7 all zipped up and ready for you to run at will: Download SQL DeveloperThe file I talk about is called Windows 64-bit - zip file includes the JDK 7
如果所有其他方法都失败了，您可以随时重新下载已经包含 jdk7 的 sqldeveloper 全部压缩并准备好让您随意运行：下载 SQL Developer我谈论的文件称为Windows 64-bit - zip file includes the JDK 7

another thing you could try is to rename your oldjdk folder, lets say its:
您可以尝试的另一件事是重命名旧的jdk 文件夹，让我们说：
C:\Program Files\Java\jdk1.7.0_04
C:\Program Files\Java\jdk1.7.0_04
change it to saomething like:
将其更改为类似：
C:\Program Files\Java\xxxjdk1.7.0_04
C:\Program Files\Java\xxxjdk1.7.0_04
Now, you should once again asked to set your jdk folder location on Oracle SqlDeveloper launch, and you can chose the right path.
现在，您应该再次要求在 Oracle SqlDeveloper 启动时设置您的 jdk 文件夹位置，您可以选择正确的路径。
Not the most elegant solution, but it worked for me.
不是最优雅的解决方案，但它对我有用。

On Windows,Close all the SQL Developer windows. Then You need to completely delete the SQL Developerand sqldeveloperfolders located in user/AppData/Roaming. Finally, run the program, you will be prompted for new JDK.
在 Windows 上，关闭所有 SQL Developer 窗口。然后您需要完全删除位于 user/AppData/Roaming的SQL Developer和sqldeveloper文件夹。最后，运行程序，会提示新的JDK。
Note that AppData is a hidden folder.
请注意，AppData 是一个隐藏文件夹。

I cannot believe Oracle's documentation is SO LAME! In some documents it is misleading people to point to the JDK by specifying the path to the JDK root, e.g. on a Mac:
我不敢相信 Oracle 的文档是如此蹩脚！在某些文档中，通过指定 JDK 根目录的路径来误导人们指向 JDK，例如在 Mac 上：
/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/
Reviewing /Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh revealed the method they use to set up the path:
查看 /Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh 揭示了他们用来设置路径的方法：
TMP_PATH=/usr/libexec/java_home -F -v 9if [ -z "$TMP_PATH" ] ; then TMP_PATH=/usr/libexec/java_home -F -v 1.8if [ -z "$TMP_PATH" ] ; then osascript -e 'tell app "System Events" to display dialog "SQL Developer requires a minimum of Java 8. \nJava 8 can be downloaded from:\n http://www.oracle.com/technetwork/java/javase/downloads/"' exit 1 fi fi
TMP_PATH=/usr/libexec/java_home -F -v 9if [ -z "$TMP_PATH" ] ; then TMP_PATH=/usr/libexec/java_home -F -v 1.8if [ -z "$TMP_PATH" ] ; then osascript -e 'tell app "System Events" to display dialog "SQL Developer requires a minimum of Java 8. \nJava 8 can be downloaded from:\n http://www.oracle.com/technetwork/java/javase/downloads/"' exit 1 fi fi
Executing this manually from Terminal:
从终端手动执行：
/usr/libexec/java_home -F -v 1.8
/usr/libexec/java_home -F -v 1.8
Lists the path as:
列出路径为：
/Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home
And this is what you need to specify as the value for
这就是您需要指定的值
SetJavaHome /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home
SetJavaHome /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home
Thank you Oracle for wasting half a day on your "product" that does NOT even support your latest Java version, also released by you.
感谢 Oracle 在您的“产品”上浪费了半天时间，该产品甚至不支持您发布的最新 Java 版本。

change back to jdk 8
