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

#注意：此处只展示打包所需的配置

3.生成可执行jar文件

• 生成jar包，项目右键：Run As –> Maven install

  

• 拷贝jar包及lib运行库到服务器上： dubbo-user-service.jar && lib
  

---

4.创建可运行脚本并配置成服务

• 目录结构（目录及文件名最好统一，便于脚本维护）
  

• 创建shell脚本：vim dubbo-user-service.sh

#!/bin/sh# chkconfig: 2345 20 80## 配置jdk路径export JAVA_HOME=/opt/jdkexport JRE_HOME=$JAVA_HOME/jre## service nameAPP_NAME=dubbo-user-serviceSERVICE_DIR=/opt/$APP_NAMESERVICE_NAME=$APP_NAMEJAR_NAME=$SERVICE_NAME\.jarPID=$SERVICE_NAME\.pidcd $SERVICE_DIRcase "$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        ;;esacexit 0

• 软链到init.d目录下

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

• 设置执行权限

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

• 注册成服务

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

• 设置开机启动

# chkconfig dubbo-user-service on

• 启动

# service dubbo-user-service start

• 停止

# service dubbo-user-service stop

• 重启

# service dubbo-user-service restart
