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

            </goals>
        </execution>
    </executions>
</plugin>

2.assembly.xml打包配置文件

<?xml version="1.0" encoding="UTF-8"?>

window启动,会打开浏览器，访问项目测试路径

bin/startup.bat

访问地址: http://localhost:8100/example/hello?name=123

响应结果:

{"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"

JAVA_OPTION配置

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}
