And you can handle the that events so easily

1. Handle ServerReadyEvent on Plugin

package com.tvd12.ezyfoxserver.embedded.test.plugin;

import com.tvd12.ezyfox.bean.annotation.EzySingleton;
import com.tvd12.ezyfox.core.annotation.EzyServerEventHandler;
import com.tvd12.ezyfoxserver.constant.EzyEventNames;
import com.tvd12.ezyfoxserver.context.EzyPluginContext;
import com.tvd12.ezyfoxserver.controller.EzyAbstractPluginEventController;
import com.tvd12.ezyfoxserver.event.EzyServerReadyEvent;

@EzyEventHandler(event = EzyEventNames.SERVER_READY)
public class HelloPluginServerReadyController 
        extends EzyAbstractPluginEventController<EzyServerReadyEvent> {

    @Override
    public void handle(EzyPluginContext ctx, EzyServerReadyEvent event) {
        logger.info("HELLO PLUGIN - SERVER READY");
    }
    
}

2. Handle ServerReadyEvent on App

package com.tvd12.ezyfoxserver.embedded.test.app.controller;

import com.tvd12.ezyfox.bean.annotation.EzySingleton;
import com.tvd12.ezyfox.core.annotation.EzyServerEventHandler;
import com.tvd12.ezyfoxserver.constant.EzyEventNames;
import com.tvd12.ezyfoxserver.context.EzyAppContext;
import com.tvd12.ezyfoxserver.controller.EzyAbstractAppEventController;
import com.tvd12.ezyfoxserver.event.EzyServerReadyEvent;

@EzyEventHandler(event = EzyEventNames.SERVER_READY)
public class HelloAppServerReadyController 
        extends EzyAbstractAppEventController<EzyServerReadyEvent> {

    @Override
    public void handle(EzyAppContext ctx, EzyServerReadyEvent event) {
        logger.info("HELLO APP - SERVER READY");
    }
    
}

3. Handle UserLoginEvent

package com.tvd12.ezyfoxserver.embedded.test.plugin;

import com.tvd12.ezyfox.bean.annotation.EzySingleton;
import com.tvd12.ezyfox.core.annotation.EzyServerEventHandler;
import com.tvd12.ezyfoxserver.constant.EzyEventNames;
import com.tvd12.ezyfoxserver.constant.EzyLoginError;
import com.tvd12.ezyfoxserver.context.EzyPluginContext;
import com.tvd12.ezyfoxserver.controller.EzyAbstractPluginEventController;
import com.tvd12.ezyfoxserver.event.EzyUserLoginEvent;
import com.tvd12.ezyfoxserver.exception.EzyLoginErrorException;

@EzyEventHandler(EzyEventNames.USER_LOGIN)
public class HelloUserLoginController 
        extends EzyAbstractPluginEventController<EzyUserLoginEvent> {

    @Override
    public void handle(EzyPluginContext ctx, EzyUserLoginEvent event) {
        logger.info("HELLO - user {} login in", event.getUsername());
        if(event.getUsername().contains("admin"))
            throw new EzyLoginErrorException(EzyLoginError.INVALID_USERNAME);
    }

}
