# 一、项目整体结构 #

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppa2UxMTIzMQ_size_16_color_FFFFFF_t_70]  
整体包括如下子服务：  
api　　　　　　　　公用的entity和service接口  
provider-log　　　　log服务提供方  
provider-message　 message服务提供方  
consumer 　　　 　 消费方

## 1.1 api公用的entity和service接口 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppa2UxMTIzMQ_size_16_color_FFFFFF_t_70 1]  
api添加两个entity和两个service，更有区分性

## 1.2 consumer消费方 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppa2UxMTIzMQ_size_16_color_FFFFFF_t_70 2]  
application.yml

server:
      port: 5051
    
    dubbo:
      application:
        name: sea-consumer-web
      registry:
        protocol: zookeeper
        address: localhost:2181
      protocol:
        name: dubbo
        port: 20551
      version: 1.0.0
      scan:
        base-packages: com.web
      consumer:
        timeout: 5000
        check: false

> dubbo.application.name 给provider起的名称 dubbo.registry.address 表示注册的地址，不一定非得是zookeeper dubbo.protocol.name 就是dubbo  
> dubbo.protocol.port 是注册的端口号，多个提供者使用的port需要区分开来  
> dubbo.protocol.scan 是表示扫描哪些包下面的服务 version是自定的一个版本属性

## 1.3 provider-log log服务提供方 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppa2UxMTIzMQ_size_16_color_FFFFFF_t_70 3]  
两个提供者provider，为的是更有区分性。  
发布的服务通过@Service注解，加载被扫描的实现类上面，这里使用的是dubbo的注解。  
SmsServiceImpl.java

package com.log.service.impl;
    
    import org.apache.dubbo.config.annotation.Service;
    import com.service.SmsService;
    
    /** * 功能描述 */
    @Service(version = "${dubbo.version}")
    public class SmsServiceImpl implements SmsService { 
    
        @Override
        public String sendMsg(String msg) { 
            System.out.println("log project");
            return "log project send msg is " + msg;
        }
    
        @Override
        public void sendMsgVoid(String msg) { 
            System.out.println("sendMsgVoid log enter");
            int i = 1 / 0;
            System.out.println("sendMsgVoid log out");
        }
    }

## 1.4 provider-message message服务提供方 ##

## 1.5 provider-xxp ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppa2UxMTIzMQ_size_16_color_FFFFFF_t_70 5]

# 二、测试发布 #

注意：一定要先保证zookeeper和dubbo服务正常启动

## 2.1 通过命令行方式查看dubbo服务 ##

telnet 192.168.153.1 20552

按回车，得到结果

## 2.2 通过Web界面查看 ##

将war包放入Tomcat的webapps目录下，解压后，将apache-tomcat-8.5.20\\webapps\\dubbo-admin-2.5.7\\WEB-INF\\dubbo.properties修改成自己的zookeeper地址，启动Tomcat，输入  
http://localhost:8080/dubbo-admin-2.5.7，账号密码默认都是root  
[war包下载地址][war].
