清除Java缓存 [英] Clear Java Cache

问题描述

我想知道如何使用Java代码或CMD Line代码清除Java缓存。

I want to know how you can clear your Java Cache using Java Code or CMD Line code.

此操作应在Windows 7或更高版本的Microsoft Windows计算机上完成。

This should be done on a Microsoft Windows Machine anywhere from Windows 7 up.

此操作应在多台计算机，因此文件路径会有所不同。

This should be done on multiple computers so the file paths will be different.

该应用程序使用Javaw作为启动时的默认应用程序（不要与Javaws或Webstart混淆-我已经拥有了代码如何清除Javaws缓存）。因此，我将需要知道如何清除Javaw缓存。

The application uses Javaw as it's default application that it launches with (Not to be confused with Javaws or Webstart - I already have code how to clear Javaws cache). So I will need to know how to clear Javaw cache.

推荐答案

创建一个名为clearCache.bat的批处理文件。

create a batch file named clearCache.bat.

@Echo Off

echo =========================

echo Now clearing all users Java cache folder

set "docandset=%homedrive%\users"

     >> c:\Delete.log echo/ "Java\Deployment\cache\6.0\"

for /f "delims=" %%a in ('dir "%docandset%" /ad /b') do (

for %%b in (

"%docandset%\%%a\AppData\LocalLow\Sun\Java\Deployment\cache\6.0"

) do (

echo %%b >> c:\Delete.log

cd /d %%b >> c:\Delete.log  2>&1

rd /s /q %%b >> c:\Delete.log  2>&1

del /f /s /q %%b >> c:\Delete.log  2>&1

)

)

echo =========================

echo COMPLETE!!!! 

echo =========================

echo All users Java cache folder has been cleared.

PAUSE

现在从命令提示符（cmd）运行批处理文件

now from command prompt(cmd) run the batch file

Runtime.getRuntime().exec("cmd /c start clearCache.bat");

它会在清除缓存后向您显示警报。

it will show you an alert after clearing the cache.
