伏羲

伏羲，是一个分布式集群业务系统。它主要由三部分组成：

• access - 负责接收客户端请求，将请求转发到servicelogic处理后响应。
• servicelogic - 负责业务插件加载及执行。
• plugin - 插件，业务处理模块。以jar包的方式载入到servicelogic中。

示例

准备

使用示例前，你需要准备好以下环境：

• zookeeper
• memcached
• 空的数据库

启动Access

Java Application的方式执行

org.bigmouth.fuhsi.access.AccessServer

启动ServiceLogic

Java Application的方式执行

org.bigmouth.fuhsi.servicelogic.ServiceLogicServer

加载插件

你需要对工程fuhsi-servicelogic-plugin-demo进行编译打包成fuhsi-servicelogic-plugin-demo-1.0.0.jar，最后将该包放到./plugins目录下，看到ServiceLogic打印如下日志即说明插件加载成功。

服务生效

已支持自动注册，不需要再人工配置。

插件成功加载到ServiceLogic系统后，还需要使服务生效才能使用，将需要生效的服务配置添加到服务配置（namecode）中，默认存储在ZooKeeper的节点路径：/FUHSI/servicelogic/cluster/namecodes。

使用客户端登录到ZooKeeper，以下两种使用方式：

• 自带zkCli

# ./zkCli.sh
# [zk: localhost:2181(CONNECTED) 2] get /FUHSI/servicelogic/cluster/namecodes
# [zk: localhost:2181(CONNECTED) 2] set /FUHSI/servicelogic/cluster/namecodes [{"plugInName":"access","plugInCode":0,"serviceName":"default","serviceCode":0},{"plugInName":"demo","plugInCode":1,"serviceName":"pair","serviceCode":0},{"plugInName":"demo","plugInCode":1,"serviceName":"demo","serviceCode":1}]

• nvwa-zkadmin 点击这里下载

进入页面后找到namecode节点，进行修改并保存。

[{"plugInName":"access","plugInCode":0,"serviceName":"default","serviceCode":0},{"plugInName":"demo","plugInCode":1,"serviceName":"pair","serviceCode":0},{"plugInName":"demo","plugInCode":1,"serviceName":"demo","serviceCode":1}]

使用服务

通过浏览器访问 ==http://localhost:8888/demo/demo== 即调用了插件中的DemoService服务。
