Linux - 通过shell脚本运行jar文件时的IO异常

Question

我正在使用Debain 8.0 - jessie（64位）。

当我尝试从目录外部通过shell脚本运行jar文件时，出现IO异常。

目录： “/家/ rscedit”

文件： “数据（目录）”， “run.sh（文件）”， “Webserver.jar（文件）”

当我尝试运行“ run.sh“，除了”/ home/rscedit“之外，我在我的jar文件中面临IO异常。

但是，如果我尝试从“/ home/rscedit”运行“run.sh”，它运行得很好。

我想在启动时运行我的shell脚本，所以我应该能够从“/ home/rscedit”外部运行我的shell脚本吧？

shell脚本

#!/bin/sh 
java -jar -Xmx20480m /home/rscedit/Webserver.jar 
read –n1 

执行我的shell脚本

        "LOG", 
        message,

     } 
    } 

} 

我用它来执行我的shell脚本的命令时，我得到的错误

exec /home/rscedit/run.sh 

编辑：我的数据地图不仅包含日志文件，还包括网站文件等其他内容。

你的java程序似乎对工作目录很敏感。我知道最简单的解决方案，改变这种

java -jar -Xmx20480m /home/rscedit/Webserver.jar 

到

(cd /home/rscedit ; java -jar -Xmx20480m Webserver.jar) 

或者，改变Java，这（和无处不在，你有图案）

loadFileLogger("ipn", "./data/log/ipn.log"); 
loadFileLogger("error", "./data/log/error.log"); 

喜欢的东西（使其相对于$HOME），

loadFileLogger("ipn", new File(System.getProperty("user.home"), 
     "data/log/ipn.log").getPath()); 
loadFileLogger("error", new File(System.getProperty("user.home"), 
     "data/log/error.log").getPath());
