分布式架构学习之：005--构建Dubbo服务的可执行jar包

Dubbo服务的运行方式：

 1、使用Servlet容器运行（Tomcat、Jetty等）----不可取缺点：增加复杂性（端口、管理）浪费资源（内存），让容器来加载spring配置等

 2、自建Main方法类来运行（Spring容器） ----不建议（本地调试可用）缺点： Dobbo本身提供的高级特性没用上自已编写启动类可能会有缺陷

public class DubboProvider {private static final Log log = LogFactory.getLog(DubboProvider.class);public static void main(String[] args) {try {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/spring-context.xml");context.start();} catch (Exception e) {log.error("== DubboProvider context start error:",e);}synchronized (DubboProvider.class) {while (true) {try {DubboProvider.class.wait();} catch (InterruptedException e) {log.error("== synchronized error:",e);}}}}    }

 3、使用Dubbo框架提供的Main方法类来运行（Spring容器）----建议使用优点：框架本身提供（com.alibaba.dubbo.container.Main）可实现优雅关机（ShutdownHook）

pom文件

注意spring-context.xml中使用import引入其他的配置文件

在Linux上手工部署

一、环境变量设置

vi /etc/profile

## java env

export JAVA_HOME=/usr/local/java/jdk1.7.0_72 export JRE_HOME=$JAVA_HOME/jre

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/li/tools.jar:$JRE_HOME/lib/rt.jar

export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

 

 source /etc/profile

二、部署目录规范

三、启动与停止

java -jar edu-service-xxx.jar &

ps -ef|grep java

kill PID

kill -9 PID

四、服务命名规范

五、服务脚本注意事项

一个脚本示例

#!/bin/sh## java envexport JAVA_HOME=/usr/local/java/jdk1.7.0_72export JRE_HOME=$JAVA_HOME/jre## service nameAPP_NAME=userSERVICE_DIR=/home/wusc/edu/service/$APP_NAMESERVICE_NAME=edu-service-$APP_NAMEJAR_NAME=$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
