Nepxion-Thunder(QQ 群 471164539)发布在https://github.com/Nepxion/
1. 运行
- 1.1 Thunder任何Demo运行之前,只需要启动Zookeeper,同时在XML里面指定Zookeeper的地址,无任何其他配置。如果是运行MQ的方式启动,则自行安装MQ(Kafka,ActiveMQ,Tibco,Redis等)
- 1.2 Thunder/ trunk / nepxion-thunder-stock / bin / application / nepxion-thunder-stock-1.0.0-bin.zip 解压,运行里面的分布式.bat,可以看到基于Thunder的股票分布式查询系统(要自行编译,每次都上传编译包,太费时了)
- 1.3 Thunder/ trunk / nepxion-thunder-test 可以看到这些通信方式的压力测试用例
- 1.4 Thunder/ trunk / nepxion-thunder / src / test / java / com / nepxion / thunder / test 有怎么使用Thunder的Demo,有5种协议方式的调用
- 1.5 Thunder/ trunk / nepxion-thunder / src / test / java / com / nepxion / thunder / trace 是比较复杂且几乎囊括了所有的调用方式,具体参考
(十四) Thunder分布式RPC框架 - 调用链
2. 示例
- 2.1 定义序列化的实体类Echo
public class Echo implements Serializable { private static final long serialVersionUID = 4670513495087782005L; private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } }
- 2.2 定义Echo的接口EchoService
public interface EchoService { Echo getEcho(String name) }
- 2.3 实现Echo的接口EchoService
public class EchoServiceImpl implements EchoService { @Override public Echo getEcho(String name) { return new Echo(); } }
- 2.4 定义服务方配置,把Echo的Service配上去,比如名字叫netty-server-context.xml

- 2.5 定义调用方方配置,把Echo的Reference配上去,比如名字叫netty-client-context.xml

框架提供更为简便的全局配置方式
