# Dubbo

## 1. Dubbo直连

### 1.1 创建父工程



### 1.2 创建01-dubbo-provider module

服务提供者

+ UserService  interface

  + hello(String name)

  ```java
  package com.sofwin.service;
  
  /**
   * @PackageName:com.sofwin.service
   * @author:andyLiu
   * @DateTime:2020/10/16 10:46
   * @Description:[TODO]输入当前模块作用
   **/
  public interface UserService {
  
      void hello(String name);
  }
  
  ```

  

+ UserServiceImpl 

  + 实现hello(String name)

  ```
  package com.sofwin.service.impl;/**
   * @PackageName:com.sofwin.service.impl
   * @author:andyLiu
   * @DateTime:2020/10/16 10:46
   * @Description:[TODO]输入当前模块作用
   **/
  
  import com.sofwin.service.UserService;
  
  /**
   * @ClassName: UserServiceImpl
   * @Description: TODO
   * @Author: andyliu
   * @Date: 2020/10/16 10:46
   * @Version: 1.0
   **/
  public class UserServiceImpl implements UserService {
      public void hello(String name) {
          System.out.println("这是服务提供者provider1,hello:"+name);
      }
  }
  
  ```

  

> 创建pom文件

+ dubbo依赖
+ spring依赖

> 测试服务提供

```java
/**
 * @PackageName:PACKAGE_NAME
 * @author:andyLiu
 * @DateTime:2020/10/16 10:55
 * @Description:[TODO]输入当前模块作用
 **/

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

/**
 * @ClassName: ProviderMain
 * @Description: TODO
 * @Author: andyliu
 * @Date: 2020/10/16 10:55
 * @Version: 1.0
 **/
public class ProviderMain {
    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        context.start();
        System.in.read();
    }
}

```



### 1.3 创建01-dubbo-consumer module

服务消费者



+ UserService interface
  + hellow(String name)

```
package com.sofwin.service;

/**
 * @PackageName:com.sofwin.service
 * @author:andyLiu
 * @DateTime:2020/10/16 10:46
 * @Description:[TODO]输入当前模块作用
 **/
public interface UserService {

    void hello(String name);
}

```



+ 测试方法

```xml
/**
 * @PackageName:PACKAGE_NAME
 * @author:andyLiu
 * @DateTime:2020/10/16 10:55
 * @Description:[TODO]输入当前模块作用
 **/

import com.sofwin.service.UserService;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

/**
 * @ClassName: ProviderMain
 * @Description: TODO
 * @Author: andyliu
 * @Date: 2020/10/16 10:55
 * @Version: 1.0
 **/
public class ConsumerMain {
    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        context.start();
        UserService service =(UserService) context.getBean("userService");
        service.hello("consumer");

    }
}

```



## 2. Dubbo使用注册中心

Dubbo：zookeeper,redis

### 2.1 创建02-dubbo-provider01 

第一个需要向注册中心注册的服务



### 2.2 创建02-dubbo-provider02

第二个向注册中心注册的服务



### 2.3 创建02-dubbo-consumer

去注册中心订阅UserService服务，每一次调用都调用不同的服务





### 2.4 dubbo启动Container

+ 在resources创建META-INFO/spring
  + spring的配置文件   名字随便
  + Dubbo  Main.main()

## 3. 搭建监控中心

是dubbo-admin,新版的dubbo-admin使用的是springboot+前后端分离

+ 安装node.js环境

安装高版本的Node.js，npm安装

在`D:\电商项目资料\dubbo\dubbo-admin-develop\dubbo-admin-develop\dubbo-admin-ui`去执行npm install

+ 使用npm对前端进行部署
+ 修改监控中心的相关配置
