创建.bat文件:

start javaw -jar %*

然后选择app default，用这个。bat文件打开。jar。

当启动.jar文件时，它将关闭cmd。

首先在cmd(命令提示符)上设置路径:

set path="C:\Program Files\Java\jre6\bin"

然后输入

java -jar yourProgramname.jar 

你需要检查一些东西;如果这是您自己的jar文件，请确保在清单中定义了main类。因为我们知道您可以从命令行运行它，所以要做的另一件事是创建一个windows快捷方式，并修改属性(您必须四处查看，我没有windows机器可以查看)，以便它在打开时执行的命令是您提到的java -jar命令。

另一件事是:如果某个东西没有混淆，它就应该工作;检查并确保已将Java与.jar扩展名关联。

不幸的是，这并不容易，因为微软在最近的Windows版本中删除了高级文件关联对话框。-对于较新的Windows版本，您可以只指定将用于打开.jar文件的应用程序。

修复在Windows上打开.jar文件需要两个步骤。

Open the Control Panel, and chose "Default Programs -> Set Associations". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)". A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button. Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. On my Windows system it looks like: C:\app\32\jre7\bin\javaw.exe" -jar "%1" %* but in most cases it is the following string: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

注:

不要在那里使用java.exe，因为它会打开shell窗口。 本线程中提到的jarfix工具很可能只是为您修改注册表。我更喜欢手动注册表更改方法，因为这意味着系统管理员可以将注册表更改“推送”到网络中的所有工作站。

最简单的方法可能是升级或重新安装Java运行时环境(JRE)。

或:

Open the Windows Explorer, from the Tools select 'Folder Options...' Click the File Types tab, scroll down and select JAR File type. Press the Advanced button. In the Edit File Type dialog box, select open in Actions box and click Edit... Press the Browse button and navigate to the location the Java interpreter javaw.exe. In the Application used to perform action field, needs to display something similar to C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe" -jar "%1" % (Note: the part starting with 'javaw' must be exactly like that; the other part of the path name can vary depending on which version of Java you're using) then press the OK buttons until all the dialogs are closed.

如果需要通过双击jar文件来运行该jar文件，则必须将其创建为“Runnable jar”。你可以简单地用你的IDE来做。

如果您正在使用eclipse，请遵循以下步骤:

    To create a new runnable JAR file in the workbench:

1.From the menu bar's File menu, select Export.
2.Expand the Java node and select Runnable JAR file. Click Next.
3.In the  Opens the Runnable JAR export wizard Runnable JAR File Specification page, select a 'Java Application' launch configuration to use to create a runnable JAR.
4.In the Export destination field, either type or click Browse to select a location for the JAR file.
5.Select an appropriate library handling strategy.
Optionally, you can also create an ANT script to quickly regenerate a previously created runnable JAR file.
