打包部署说白了就两步：打包、部署。废话不多说，直接拿spring boot自动生成的项目骨架，再添加一个文件用来演示：
package com.crocodile.springboot; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController public class PDFController { @RequestMapping(value = "hello", method = RequestMethod.GET) public String helloWorld() { return "hello, world."; } }
还要在配置文件application.properties里加两个配置项：
#修改tomcat的默认的端口号，将8080改为8888
server.port=8888
#切换配置文件
spring.profiles.active=test
最后打包，直接跑Maven生成jar包就好了。
打完包就要部署了。因为spring boot有内置tomcat容器，这点比较方便，省去了tomcat的部署。我们直接把jar包扔到linux上。这里你可以通过FTP工具，也可以使用下面这个命令行的小工具，先安装：
yum -y install lrzsz Loaded plugins: fastestmirror Determining fastest mirrors base | 3.6 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/2): epel/x86_64/updateinfo | 1.0 MB 00:00:00 (2/2): epel/x86_64/primary_db | 6.6 MB 00:00:00 Package lrzsz-0.12.20-36.el7.x86_64 already installed and latest version Nothing to do
再上传：
rz -y
rz waiting to receive.
zmodem trl+C ȡ
它会弹出一个界面让你选择具体文件的，你选择maven打好的jar后点击发送就ok了。
接着就是执行jar包，这里通过一个脚本来执行：
#!/bin/sh JAR_NAME=springboot-0.0.1-SNAPSHOT.jar tpid=`ps -ef|grep $JAR_NAME|grep -v grep|grep -v kill|awk '{print $2}'` if [ ${tpid} ]; then echo 'Stop Process...' fi sleep 5 tpid=`ps -ef|grep $JAR_NAME|grep -v grep|grep -v kill|awk '{print $2}'` if [ ${tpid} ]; then echo 'Kill Process!' kill -9 $tpid else echo 'Stop Success!' fi tpid=`ps -ef|grep $JAR_NAME|grep -v grep|grep -v kill|awk '{print $2}'` if [ ${tpid} ]; then echo 'App is running.' else echo 'App is NOT running.' fi rm -f tpid nohup java -jar ./$JAR_NAME --spring.profiles.active=test & echo $! > tpid echo 'Start Success!'
这个脚本的作用就是通过jar命令来执行jar包，前面是先通过grep命令看是否已有jar包在跑，有的话就杀掉再拉起，没有就直接跑。注意上面的JAR_NAME需要根据你的jar包名称赋值。保存好脚本后还得给这个脚本加权限：
chmod +x start.sh
打完收工，你可以直接用它跑了：
./start.sh Stop Process... Kill Process! App is NOT running. Start Success!
上面是我已经把jar起好了，再次执行start.sh后，它先停掉进程后又拉了起来。可以看下日志
