新增一个模块专门记录路由eternity-command ServerTag.java
public interface ServerTag {/**** 打招呼*/int TAG_HELLO_HI 1;}
ServerTopic.java
public interface ServerTopic {/**** 问候*/int TOPIC_HELLO 1;}
然后再core中引入这个模块同时增加反射依赖 dependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencydependencygroupIdorg.reflections/groupIdartifactIdreflections/artifactIdversion0.9.10/version/dependencydependencygroupIdcom.loveprogrammer/groupIdartifactIdeternity-common/artifactIdversion1.0-SNAPSHOT/version/dependencydependencygroupIdcom.loveprogrammer/groupIdartifactIdeternity-command/artifactIdversion1.0-SNAPSHOT/version/dependency/dependencies
在core中增加一个文件夹 创建两个注解
TagListener
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.METHOD;Retention(RetentionPolicy.RUNTIME)
Target(ElementType.METHOD)
public interface TagListener {/*** 订阅的tag*/int tag() default 0;/*** 请求方消息类型*/Class? messageClass() default Object.class;}TopicListener
Retention(RetentionPolicy.RUNTIME)
Target(ElementType.TYPE)
public interface TopicListener {/*** 订阅的主题*/int topic() default 0;
}
接口IHandler
public interface IHandler {}抽象实现类BaseHandler
public abstract class BaseHandler implements IHandler{}
hello实现类 import com.loveprogrammer.base.network.command.BaseHandler;
import com.loveprogrammer.base.network.command.HandlerFactory;

TopicListener(topic ServerTopic.TOPIC_HELLO)
public class HelloHandler extends BaseHandler {public static final Logger log LoggerFactory.getLogger(HelloHandler.class);TagListener(tag ServerTag.TAG_HELLO_HI,messageClass String.class)public void sayHi(Channel channel, String msg){log.info(say hi);}
}创建监听器工厂 HandlerFactory import com.loveprogrammer.base.network.command.anotation.TopicListener;

public class HandlerFactory implements CommandLineRunner {public static final Logger log LoggerFactory.getLogger(HandlerFactory.class);public MapInteger, Class handlerMap new HashMap();Overridepublic void run(String... args) throws Exception {// 找到所有实现类Reflections reflections new Reflections(com.loveprogrammer.base.network.command.handler);// 获取在指定包扫描的目录所有的实现类SetClass? extends BaseHandler classes reflections.getSubTypesOf(BaseHandler.class);for (Class? extends IHandler aClass : classes) {try {TopicListener listeners aClass.getAnnotation(TopicListener.class);Integer topic listeners.topic();handlerMap.put(topic, aClass);log.info(初始化消息监听器成功 {},aClass.getName());} catch (Exception e) {log.error(初始化 aClass.getName() 消息监听器失败,e);}}}
}启动server查看监听器是否初始化成功。
