好消息,支撑微博千亿调用的轻量级 RPC 框架 Motan 在2016年5月份正式开源了,业界现在除了Dubbo 和 DubboX典型的分布式RPC服务治理型框架外,又多了一个优秀的分布式RPC了。心动了吗?使用过dubbo的话,so easy的上手,官方实例如下,动起来吧
我的demo地址,参考官方实例的简单demo,包含zookeeper注册中心,以及服务监控平台:https://coding.net/u/kailingchen/p/motan_Test/git
Motan是一套高性能、易于使用的分布式远程服务调用(RPC)框架。

执行Server类中的main函数将会启动Motan服务,并监听8002端口.

执行Client类中的main函数将执行一次远程调用,并输出结果。
在集群环境下使用Motan需要依赖外部服务发现组件,目前支持consul或zookeeper。
Consul安装与启动
安装(官方文档)

# 这里以linux为例 wget https://releases.hashicorp.com/consul/0.6.4/consul_0.6.4_linux_amd64.zip unzip consul_0.6.4_linux_amd64.zip sudo mv consul /bin |
启动(官方文档)
1 2 |
测试环境启动: consul agent -dev |
ui后台 http://localhost:8500/ui
在server和client中添加motan-registry-consul依赖
1 2 3 4 5 |
<dependency> <groupId>com.weibogroupId> <artifactId>motan-registry-consulartifactId> <version>0.1.1version> <dependency> |
在server和client的配置文件中分别增加consul registry定义。
1 |
<motan:registry regProtocol="consul" name="my_consul" address="127.0.0.1:8500"/> |
在Motan client及server配置改为通过registry服务发现。
client
1 |
<motan:referer id="remoteService" interface="quickstart.FooService" registry="my_consul"/> |
server
1 |
<motan:service interface="quickstart.FooService" ref="serviceImpl" registry="my_consul" export="8002" /> |
server程序启动后,需要显式调用心跳开关,注册到consul。

MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true) |
进入ui后台查看服务是否正常提供调用
启动client,调用服务
ZooKeeper安装与启动

<dependency> <groupId>com.weibogroupId> <artifactId>motan-registry-zookeeperartifactId> <version>0.1.1version> <dependency> |
在server和client的配置文件中分别增加zookeeper registry定义。
zookeeper为单节点
1 |
<motan:registry regProtocol="zookeeper" name="my_zookeeper" address="127.0.0.1:2181"/> |
zookeeper多节点集群
1 |
<motan:registry regProtocol="zookeeper" name="my_zookeeper" address="127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183"/> |
在Motan client及server配置改为通过registry服务发现。
client
1 |
<motan:referer id="remoteService" interface="quickstart.FooService" registry="my_zookeeper"/> |
server
1 |
<motan:service interface="quickstart.FooService" ref="serviceImpl" registry="my_zookeeper" export="8002" /> |
server程序启动后,需要显式调用心跳开关,注册到zookeeper。
