Spring Boot项目使用maven-assembly-plugin根据不同环境打包成tar.gz或者zip

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

主要插件

maven-assembly-plugin

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:8080/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}

项目历史运行日志存储路径,每启动一次项目,会将之前的运行日志移动到back目录

`-- logs
    |-- back
    |   |-- spring-boot-assembly_back_2018-12-12-23-30-10.log
    |   `-- spring-boot-assembly_back_2018-12-12-23-36-56.log
    |-- spring-boot-assembly.log
    `-- spring-boot-assembly_startup.log

 

maven项目打包

1. 使用IDEA工具打包,选择对应的profiles,然后clean package

 

2. 使用maven命令打包

mvn clean package -Pdev

 

3. 使用mvn-package脚本打包

window

mvn-package.bat dev

 

linux/mac

sh mvn-package.sh dev

 

FAQ

Q: 项目打成tar包后,不能正常读取resource目录下的某些配置文件

A:如果resource目录中还用到其它配置文件,需要在pom.xml和assembly.xml文件的resource中进行配置

pom.xml中的resource默认配置
把需要打包的文件添加到include中

<!-- 资源文件配置 -->
<resource>
    <directory>src/main/resources</directory>
    <filtering>true</filtering>
    <includes>
        <include>application.yml</include>
        <include>application-${profileActive}.yml</include>
        <include>mapper/**/*.xml</include>
        <include>static/**</include>
        <include>templates/**</include>
        <include>*.xml</include>
        <include>*.properties</include>
        <!-- xxx.keystore -->
        <include>xxx.keystore</include>
    </includes>
</resource>

 

assembly.xml中的resource默认配置
把需要打包的文件添加到include中

<!-- 指定输出target/classes中的配置文件到config目录中 -->
<fileSet>
    <directory>${basedir}/target/classes</directory>
    <outputDirectory>config</outputDirectory>
    <fileMode>0644</fileMode>
    <includes>
        <include>application.yml</include>
        <include>application-${profileActive}.yml</include>
        <include>mapper/**/*.xml</include>
        <include>static/**</include>
        <include>templates/**</include>
        <include>*.xml</include>
        <include>*.properties</include>
        <!-- xxx.keystore -->
        <include>xxx.keystore</include>
    </includes>
</fileSet>

# 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
