4、启动jetty_dev
ps -ef |grep jetty_dev
1083 8099 1 0 Sep06 ? 00:01:24 /opt/java/bin/java -Xmx512m -Xms512m -Xss256k -XX:MaxPermSize=256m -Djava.awt.headless=true
-Dspring.profiles.active=test -Djetty.state=/opt/jetty_dev/jetty.state -Djetty.home=/opt/jetty_dev -Djava.io.tmpdir=/tmp -jar /opt/jetty_dev/start.jar --daemon
在/etc/init.d/jetty_dev中添加
JAVA_OPTIONS="-Xmx512m -Xms512m -Xss256k -XX:MaxPermSize=256m -Djava.awt.headless=true -Dspring.profiles.active=test"
