java - Linux 运行有依赖的Jar失败

Answer 1

Use -Djava.ext.dirs directly to automatically load JAR files, eliminating the need to load them one by one.

java -Djava.ext.dirs=$RUN_LIB -jar *.jar > $LOG_FILE  &

Answer 2

First: *.jar should be avoided writing this way. If one day a teammate throws a jar package into it for you, problems may occur.

Second: In your shell script:

LIB_CLASS = '.'

This . should refer to the crontab working directory (PWD), which is the user’s default directory, so if you have a class file under /home/user/crontab-job/projectX, your classpath It should not be included.
