我用bat文件执行java程序，我在里面set了classpath，可是执行的时候说的太长了，怎么解决？

Question

恩。。可以先在系统环境变量设定好的了
我得电脑－》属性－》高级－》环境变量——》
 设定path 和JAVA_HOMEL

Answer 1

晕呀，哥们!
您可以先设一个变量
如：set libhome=C:\eclipse\workspace\MagicGame
然后在ClassPath里再用他
如：java.exe -classpath "%libhome%\MagicGame.zip;" magic.TryMagic
这里是你的Class的包路径，不是系统包，晕拉晕拉

Answer 2

这样分开写好像不对，分开写是怎么写的？

Answer 3

呵呵，不是拉，误解
你打包不可能打出这么多包的，最多只有一个，你只要写一个就可以了，那些系统包不用去理会他，给你一个例子吧!
echo off
set libhome=C:\eclipse\workspace\MagicGame
java.exe -classpath "%libhome%\MagicGame.zip;" magic.TryMagic
这里，MagicGame.zip是我打的包
magic.TryMagic是含有Main函数的类名
just so

trust me baby, you can take it!

Answer 5

多设置一些变量就好了
set jdbc=XXXX;
set jre=XXX;
set classpath=%jre%;%jdbc%;
