springboot启动脚本start.sh和停止脚本 stop.sh

我们在项目中都会遇到项目打包，可以通过assembly对我们的项目进行打包。  
针对打包构建jar包，本文不再叙述。具体可以参考[maven插件assembly使用及springboot启动脚本start.sh和停止脚本 stop.sh][maven_assembly_springboot_start.sh_ stop.sh]

这里面已经有一个springboot 的启动脚本了，本文之所以还要写，是因为之前的脚本存在一个问题。关闭脚本的时候是通过kill -9 命令进行的，但其实我们项目中可能很多时候不能强制关闭的，在关闭之前需要做一些事情。比如将内存数据存到磁盘，dubbo清空zookeeper里面的固定节点 等等。

这里将启动脚本环境变量抽出来作为一个文件来使用：

setenv.sh

#!/usr/bin/env bash
    
    PIDFILE=server.pid
    
    if [ "$JAVA_HOME" != "" ]; then
     JAVA="$JAVA_HOME/bin/java"
     else
      JAVA=java
     fi
    
     JAVA_OPTS="-server -Xms32m -Xmx32m -Xmn24m -Xss256K -XX:MetaspaceSize=10m -DHADOOP_USER_NAME=root
                -XX:SurvivorRatio=4  -XX:+UseConcMarkSweepGC \
                -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=10 \
                -XX:CMSInitiatingOccupancyFraction=60 -XX:+AggressiveOpts \
                -XX:+UseFastAccessorMethods \
    	    -XX:+HeapDumpOnOutOfMemoryError \
    	    -XX:HeapDumpPath=$base_dir/dump.dump
                -XX:+PrintGCDateStamps -XX:+PrintGCDetails \
                -Xloggc:$base_dir/gc.log"

start.sh 启动脚本：
