What's the ZNS is an implementation of distribution RPC.
ZNS是一个分布式RPC框架。
-
通过Zookeeper实现服务的注册与发现
-
基于Netty实现底层网络通信
-
采用Spring实现最小依赖注入
- 服务注册
- 服务发现
- 网络通信层
- 服务异步调用
- 灵活的水平扩容、缩容
- 服务生产者与Zookeeper心跳机制
- 更多的集群服务路由策略
- 服务监控
- 服务降级
- 服务版本控制
ZNS 服务端：提供了服务注册，接受client端Connector连接，反射调用服务等
ZNS 客户端：提供了服务发现，请求连接server端Acceptor，服务代理等
- 添加
zns-server依赖包
<dependency>
<groupId>com.buildupchao</groupId>
<artifactId>zns-service-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
</exclusion>
</exclusions>
</dependency>
- 添加扫描包路径
ZnsServerPackage.class以及启动调用方法znsServerRunner.run()
@ComponentScan(
basePackages = "com.buildupchao.zns.service.provider",
basePackageClasses = ZnsServerPackage.class
)
@SpringBootApplication
public class ZnsServiceProviderApplication implements ApplicationRunner {
private static final Logger LOGGER = LoggerFactory.getLogger(ZnsServiceProviderApplication.class);
@Autowired
private ZnsServerRunner znsServerRunner;
public static void main(String[] args) {
SpringApplication.run(ZnsServiceProviderApplication.class, args);
LOGGER.info("Zns service provider application startup successfully");
}
@Override
public void run(ApplicationArguments applicationArguments) throws Exception {
znsServerRunner.run();
}
}
- 在application.yml中配置属性
zns:
server:
zk:
root: /zns
addr: localhost:2181
switch: true
network:
port: 8888
- 添加
zns-client依赖包
<dependency>
<groupId>com.buildupchao</groupId>
<artifactId>zns-client</artifactId>
<version>1.0-SNAPSHOT</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
</exclusion>
</exclusions>
</dependency>
- 添加扫描包路径
ZnsClientPackage.class以及启动调用方法znsClientRunner.run()
@ComponentScan(
basePackages = "com.buildupchao.zns.service.consumer",
basePackageClasses = ZnsClientPackage.class
)
@SpringBootApplication
public class ZnsServiceConsumerApplication implements ApplicationRunner {
@Autowired
private ZnsClientRunner znsClientRunner;
public static void main(String[] args) {
SpringApplication.run(ZnsServiceConsumerApplication.class, args);
}
@Override
public void run(ApplicationArguments applicationArguments) throws Exception {
znsClientRunner.run();
}
}
- 在application.yml中配置属性
zns:
client:
zk:
root: /zns
addr: localhost:2181
switch: true
api:
package: com.buildupchao.zns.service.api
<dependency>
<groupId>com.buildupchao</groupId>
<artifactId>zns-api</artifactId>
<version>1.0-SNAPSHOT</version>
