解决Spring Cloud 部署war包到tomcat 注册不到consul 服务

本问题是部署问题所以很麻烦一遍一遍打包，一遍一遍测试，终于得以解决这破壁问题。。。。。。。

开始！

这里配置打包的步骤就不写了，直接写解决问题的步骤。

介绍：    Spring Cloud 2.1之后 注册服务是通过今天WebServerInitializedEvent 事件进行的，这个事件是干啥的呢

就是算计应用程序上下文并准备好web服务器后发布，用于获取正在运行的服务器的本地端口。

但是现在通过tomcat容器启动服务时监听不到WebServerInitializedEvent事件 。

那就自己创建一个事件去监听

代码：

package cn.com.dyrs.cmp.structure.provider.config;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.cloud.consul.discovery.ConsulDiscoveryProperties;
    import org.springframework.cloud.consul.serviceregistry.ConsulAutoServiceRegistration;
    import org.springframework.context.ApplicationListener;
    import org.springframework.context.event.ContextRefreshedEvent;
    import org.springframework.stereotype.Component;
    
    /**
     * @author 荡漾
     * @title: ConsulEventLinsiner
     * @projectName cmp
     * @description: TODO  Consul注册
     * @date 2019/7/12  12:58
     */
    
    @Component
    public class ConsulEventLinsiner implements ApplicationListener<ContextRefreshedEvent> {
    	@Autowired
    	ConsulAutoServiceRegistration consulAutoServiceRegistration;
    	@Autowired
    	ConsulDiscoveryProperties properties;
    	@Override
    	public void onApplicationEvent(ContextRefreshedEvent event) {
    		consulAutoServiceRegistration.start();
    	}
     
    }

添加好这个还没玩，还要改一个地方，就是consul 的 discovery 参数

到配置文件当中添加一个port 加的是你工程的端口

这个不加还是会报错的           这是错误信息:service.port has not been set

这就玩活了
