SpringBoot项目发布及启动(19)

发布jar到指定目录

添加maven插件

需要使用maven-antrun-plugin插件把jar包发布到release/lib目录下

    <build>
        <finalName>build-app</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!--把包发布到应用的build目录下面和项目名相应的目录下面-->
            <plugin>
                <artifactId>maven-antrun-plugin</artifactId>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>run</goal>
                        </goals>
                        <configuration>
                            <tasks>
                                <copy todir="release/lib/" overwrite="true">
                                    <fileset dir="${project.build.directory}" erroronmissingdir="false">
                                        <include name="*.jar"/>
                                    </fileset>
                                </copy>
                            </tasks>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

执行打包命令

在应用根路径下面,执行以下命令

mvn clean package

可以看到jar包已经发布到了release的lib目录下

启动脚本

linux启动脚本

脚本内容

只需要修改SERVER_NAME属性即可使用脚本
server.sh脚本内容如下

#:!/bin/bash

BASE_DIR=$(cd $(dirname $0);cd ..; pwd)
echo "Welcome enter $BASE_DIR"
cd $BASE_DIR

#启动的jar存放路径(需要换成你jar包的位置)
SERVER_NAME=build-app.jar

SERVER_PATH="lib/${SERVER_NAME}"
#程序的外部配置文件路径,这里使用了相对路径
CONFIG=conf/application.yml
#日志文件的路径
LOG_CONFIG=conf/logback-spring.xml
#nohup命令的日志输出路径,
CONSOLE_LOG_OUT=logs/server-console.log

#设置最小堆内存 最大堆内存 年轻代堆内存 初始化元空间内存  最大元空间内存 (元空间是jdk1.8才有的,jdk1.8之前叫永久代,jvm知识请阅读方志明老师写的深入理解Java虚拟机)
JAVA_OPT='-Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=256m'
#设置内存溢出打印堆日志
JAVA_OPT="${JAVA_OPT} -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${BASE_DIR}/logs/heapdump.hprof"
#设置GC输出日志 ,测试环境可以打印,生产环境需要注释掉
JAVA_OPT="${JAVA_OPT} -XX:+PrintGCDetails  -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -Xloggc:${BASE_DIR}/logs/gc.log"

#设置启动程序需要指定的spring配置信息
JAVA_OPT="${JAVA_OPT} -jar  ${SERVER_PATH} "
JAVA_OPT="${JAVA_OPT} --spring.config.location=${CONFIG}"
JAVA_OPT="${JAVA_OPT} --logging.config=${LOG_CONFIG}"

if [ ! -d "logs" ] ;
then
  echo 'mkdir logs dir'
  mkdir -p "logs"
fi

function start() {
    PID=$(ps -ef | grep $SERVER_NAME | grep -v grep | awk '{ print $2 }')
    if [ -z "$PID" ]
	    then
	    echo will start ...
    else
	    echo "Start fail, app runing. at $CURRENT_DIR, pid=$PID"
	    exit 1
    fi
    echo '-----print JAVA_OPT------'
    echo $JAVA_OPT
    #把启动命令里的  >$CONSOLE_LOG_OUT 2>&1 &  换成 >dev/null & 可以让nohup不输出启动日志,改成>dev/null的话记得把 tail -f
    nohup java $JAVA_OPT >$CONSOLE_LOG_OUT 2>&1 &
    #查看实时的启动日志
    tail -f $CONSOLE_LOG_OUT
}

function stop() {
    PID=$(ps -ef | grep $SERVER_NAME | grep -v grep | awk '{ print $2 }')
    if [ -z "$PID" ]
	    then
	    echo Application is already stopped
    else
	    echo kill $PID
	    kill  $PID
    fi
}

#根据启动脚本的第1个参数决定调用哪个方法
# 启动 start,停止 stop, 重启 restart
case $1 in
    start)
      shift 1
      start $@
      ;;
    stop)
      shift 1
      stop
      ;;
    restart)
      shift 1
      stop
      sleep 3
      start $@
      ;;
esac　

启动

#修改server.sh脚本,把SERVER_NAME改成你的jar包的名称
vi bin/server.sh
#给刚上传到服务器的脚本文件分配执行的权限
chmod 777 bin/server.sh
#启动程序
bin/server.sh start

停止

bin/server.sh stop　

重启

重启命令相当于 stop和start 的组合命令

bin/server.sh restart　

window脚本

启动脚本

bin/startup.cmd

只需要修改SERVER_NAME属性,然后双击此脚本即可启动程序

@echo off

@echo Please do not close the current window.
@echo -----print JAVA_OPT------
@echo %JAVA_OPT%

双击release/bin/startup.cmd启动程序

停止脚本

shutdown.cmd
需要把脚本中的build-app换成你jar包的名称,然后双击此脚本既可以停止应用

@echo off
if not exist "%JAVA_HOME%injps.exe" echo Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better! & EXIT /B 1

setlocal

set "PATH=%JAVA_HOME%in;%PATH%"

echo killing build-app server

for /f "tokens=1" %%i in ('jps -m ^| find "build-app"') do ( taskkill /F /PID %%i )

echo Done!
