spring-boot-assembly
- 在spring boot项目中使用maven profiles和maven assembly插件根据不同环境打包成tar.gz或者zip
- 将spring boot项目中的配置文件提取到外部config目录中
- 将spring boot项目中的启动jar包移动到boot目录中
- 将spring boot项目中的第三方依赖jar包移动到外部lib目录中
- bin目录中是启动，停止，重启服务命令
- 打包后的目录结构类似于tomcat/maven目录结构

window启动,会打开浏览器，访问项目测试路径
bin/startup.bat
{"msg":"service hello:123","code":200}
linux启动，停止，重启
sh bin/startup.sh 启动项目
sh bin/shutdown.sh 停止服务
sh bin/restart.sh 重启服务
startup.sh 脚本中的主要内容
- 配置项目名称及项目启动jar名称，默认项目名称与启动jar名称一致
APPLICATION="spring-boot-assembly"
APPLICATION_JAR="${APPLICATION}.jar"
- JVM Configuration
- -Xmx256m:设置JVM最大可用内存为256m,根据项目实际情况而定，建议最小和最大设置成一样。
- -Xms256m:设置JVM初始内存。此值可以设置与-Xmx相同,以避免每次垃圾回收完成后JVM重新分配内存
- -Xmn512m:设置年轻代大小为512m。整个JVM内存大小=年轻代大小 + 年老代大小 + 持久代大小。持久代一般固定大小为64m,所以增大年轻代,将会减小年老代大小。此值对系统性能影响较大,Sun官方推荐配置为整个堆的3/8
- -XX:MetaspaceSize=64m:存储class的内存大小,该值越大触发Metaspace GC的时机就越晚
- -XX:MaxMetaspaceSize=320m:限制Metaspace增长的上限，防止因为某些情况导致Metaspace无限的使用本地内存，影响到其他程序
- -XX:-OmitStackTraceInFastThrow:解决重复异常不打印堆栈信息问题
JAVA_OPT="-server -Xms256m -Xmx256m -Xmn512m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=256m"
JAVA_OPT="${JAVA_OPT} -XX:-OmitStackTraceInFastThrow"
执行启动命令：后台启动项目,并将日志输出到项目根目录下的logs文件夹下
nohup java ${JAVA_OPT} -jar ${BASE_PATH}/boot/${APPLICATION_JAR} --spring.config.location=${CONFIG_DIR} > ${LOG_PATH} 2>&1 &
最终执行jar包的命令
nohup java -server -Xms256m -Xmx256m -Xmn512m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=256m -XX:-OmitStackTraceInFastThrow -jar /opt/spring-boot-assembly/boot/spring-boot-assembly.jar --spring.config.location=/opt/spring-boot-assembly/config/ > /opt/spring-boot-assembly/logs/spring-boot-assembly.log 2>&1 &
- nohup：在后台运行jar包，然后将运行日志输出到指定位置
- -server：指定JVM参数
- -jar /opt/spring-boot-assembly/boot/spring-boot-assembly.jar：指定启动的jar包
- 启动命令中指定的启动jar包路径，配置文件路径，日志路径都是绝对路径
- 可在任何位置执行start.sh,shutdown.sh,restart.sh脚本
- --spring.config.location：指定配置文件目录或者文件名称，如果是目录，以/结束
- > /opt/spring-boot-assembly/logs/spring-boot-assembly.log：指定日志输出路径
- 2>&1 & ：将正常的运行日志和错误日志合并输入到指定日志，并在后台运行
shutdown.sh停服脚本，实现方式：找到当前项目的PID，然后kill -9
PID=$(ps -ef | grep "${APPLICATION_JAR}" | grep -v grep | awk '{ print $2 }')
kill -9 ${PID}
