使用Maven构建Dubbo服务的可运行jar包 支持优雅关机

1.Dubbo项目结构如图

2. pom文件配置

<build>
<finalName>dubbo-user-service</finalName> <!--包名称 -->
<resources>
<resource>
<targetPath>${project.build.directory}/classes</targetPath>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes><!-- 配置文件信息 -->
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
<resource>
<targetPath>${project.build.directory}/classes/META-INF/spring</targetPath>
<directory>src/main/resources/spring</directory>
<filtering>true</filtering>
<includes><!--com.alibaba.dubbo.container.Main做为启动入口需要将spring配置文件拷贝到/classes/META-INF/spring目录下， -->
<include>*.xml</include>
</includes>
</resource>
</resources>

3.生成可执行jar文件

4.创建可运行脚本并配置成服务

#!/bin/sh
# chkconfig: 2345 20 80
## 配置jdk路径
export JAVA_HOME=/opt/jdk
export JRE_HOME=$JAVA_HOME/jre

## service name
APP_NAME=dubbo-user-service

SERVICE_DIR=/opt/$APP_NAME
SERVICE_NAME=$APP_NAME
JAR_NAME=$SERVICE_NAME\.jar
PID=$SERVICE_NAME\.pid

cd $SERVICE_DIR

case "$1" in

start)
nohup $JRE_HOME/bin/java -Xms256m -Xmx512m -jar $JAR_NAME >/dev/null 2>&1 &
echo $! > $SERVICE_DIR/$PID
echo "=== start $SERVICE_NAME"
;;

stop)
kill `cat $SERVICE_DIR/$PID`
rm -rf $SERVICE_DIR/$PID
echo "=== stop $SERVICE_NAME"

sleep 5
##
## edu-service-aa.jar
## edu-service-aa-bb.jar
P_ID=`ps -ef | grep -w "$SERVICE_NAME" | grep -v "grep" | awk '{print $2}'`
if [ "$P_ID" == "" ]; then
echo "=== $SERVICE_NAME process not exists or stop success"
else
echo "=== $SERVICE_NAME process pid is:$P_ID"
echo "=== begin kill $SERVICE_NAME process, pid is:$P_ID"
kill -9 $P_ID
fi
;;

restart)
$0 stop
sleep 2
$0 start
echo "=== restart $SERVICE_NAME"
;;

*)
## restart
$0 stop
sleep 2
$0 start
;;

esac
exit 0

# cd /etc/init.d/

# ln -s /opt/dubbo-user-service/dubbo-user-service.sh /etc/init.d/dubbo-user-service

# chmod a+x ./dubbo-user-service

# chkconfig --add dubbo-user-service
# chkconfig --list #可查看配置的服务

# chkconfig dubbo-user-service on

# service dubbo-user-service start

# service dubbo-user-service stop

# service dubbo-user-service restart
