-rw-r--r--  1 knightliao  staff  12927960  6  3 17:23 starter-shade-demo.tar.gz

其中

  • starter-run 是可部署的环境，包含所有可执行脚本以及jar包的文件目录
  • starter-shade-demo.tar.gz 是对 starter-run 目录的打包

starter-run目录

➜  target git:(master) cd starter-run
➜  starter-run git:(master) ls -l
total 27592

-rw-r--r--  1 knightliao  staff       532  6  3 17:23 stop.sh

其中

  • start.sh 是开始脚本, 插件自动生成的
  • stop.sh 是关闭脚本, 插件自动生成的
  • env 是启动前的环境变量设置

env文件

➜  starter-run git:(master) cat env

BUNDLE_JAR_NAME=starter-shade-demo.jar

export JAVA_OPTS="$JAVA_OPTS -server -Xms1024m -Xmx1024m -Xmn448m -Xss256K -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m"
export JAVA_OPTS="$JAVA_OPTS -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:ParallelGCThreads=2"
export JAVA_OPTS="$JAVA_OPTS -XX:+PrintGCDetails -XX:+PrintGCTimeStamps"
export JAVA_OPTS="$JAVA_OPTS -Dlogback.configurationFile=file:logback.xml"

其中

  • 必须设置 BUNDLE_JAR_NAME ，否则 start.sh 无法启动
  • 其它参数可配

执行、查看日志和关闭

➜  starter-run git:(master) sh start.sh
