现在很流行的Dubbo很多朋友都听说过吧,最近我也在看这方面的东西,分享先我的心得笔记。
先说说我们团队要做的项目框架,很简单重在实现基于zookeeper的dubbo注册。
框架:springmvc+spring+mybatis+shiro+zookeeper+dubbo
项目分三层,model存放数据,view页面展示、controller下面具体逻辑实现。通过dubbo消费方和供应方注册,供应方给消费方暴露接口,供消费方调用。
工程部署需要配置文件有:
spring-provider-dubbo.xml(提供方配置文件)
<span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd "> <!--dubbo 服务提供者应用名称 --> <dubbo:application name="demo-dubbo-provider-app" /> <!--dubbo 注册中心--> <dubbo:registry address="zookeeper://192.168.1.125:2181" /> <!--服务提供者 端口--> <dubbo:protocol name="dubbo" port="30001" /> <!--dubbo提供服务--> <dubbo:service interface="com.swrac.www.testdubbo.IGoodsManager" ref="goodsService" /> <!--spring bean 对象--> <bean id="goodsService" class="com.swrac.www.testdubbo.impl.GoodsManager" /> </beans></span>
spring-consumer-dubbo.xml(消费方配置文件)
{--
<-- 消费方应用名,用于计算依赖关系,不是匹配条件,不要与提供方一样 -->
<-- 使用zookeeper注册中心暴露服务地址 -->
<-- 生成远程服务代理,可以像使用本地bean一样使用demoService -->
<dubbo:reference id="demoService" interface="com.unj.dubbotest.provider.DemoService" />
--}
例如我的配置:
<span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd "> <dubbo:application name="demo-dubbo-consumer-app" /> <dubbo:registry address="zookeeper://192.168.1.125:2181" /> <!-- 和本地bean一样实现服务 --> <bean id="goodsService" class="com.swrac.www.testdubbo.impl.GoodsManager" /> </beans></span>
dubbo.properties
{--
<--基于ZooKeeper的Dubbo注册中心直接部署tomcat,修改WEB-INF下文件-->
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest
--}
本人的配置如下:
<span style="font-size:14px;">dubbo.registry.address=zookeeper://127.0.0.1:2181 dubbo.admin.root.password=root dubbo.admin.guest.password=guest</span>
zoo_sample.cfg
{--
zookeeper/conf/下,修改zoo_sample.cfg为zoo.cfg,启动bin/下zkServer.cmd
--}
本人的配置如下:
# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=D:\\Java\\zookeeper-3.4.5\\data dataLogDir=D:\\Java\\zookeeper-3.4.5\\log # the port at which the clients will connect clientPort=2181 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir # autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature # autopurge.purgeInterval=1
因为引入dubbo,摒弃了原有Web Service项目的wdls暴露,由于项目依赖关系严重,项目使用maven构建,通过Maven pom.xml三维坐标引入jar包,调用dubbo暴露接口开发。
