java - 使用 cronjob 运行 JAVA 的 Linux 命令

Question

我正在尝试设置一个 cronjob (cPanel) 来执行将运行 java 应用程序的 shell 文件。但是我无法使类路径起作用。

JAVA文件夹应用路径

/home/user/public_html/version_1/data/downloader

.sh 文件中的这个命令在通过终端和 JAVA 应用程序文件夹中运行时有效

java -cp .:download.jar:log4j.jar:commons-httpclient.jar:commons-fileupload.jar:commons-logging.jar:commons-codec.jar:JAxe-1.0.jar portal.client.Main login

但是，当在文件夹外运行时，它不起作用并返回以下错误

Error: Could not find or load main class portal.client.Main

所以我尝试特定的类路径

java -cp /home/user/public_html/version_1/data/downloader/*:.download.jar:log4j.jar:commons-httpclient.jar:commons-fileupload.jar:commons-logging.jar:commons-codec.jar:JAxe-1.0.jar th.or.set.portal.client.Main login

还是报错

log4j:ERROR Could not read configuration file [log4j.properties].
java.io.FileNotFoundException: log4j.properties (No such file or directory)

Answer 1

嗯。您需要更改工作目录。您可以简单地使用 cd 来完成。

cd /home/user/public_html/version_1/data/downloader/
java -cp .:download.jar:log4j.jar:commons-httpclient.jar:commons-fileupload.jar:commons-logging.jar:commons-codec.jar:JAxe-1.0.jar portal.client.Main login
