springboot整合dubbo

准备

因为使用springboot2.0，需要jdk1.8
然后需要对springboot基本了解

搭建注册中心（zookerper）

1、下载windows版本的zookerper

下载地址：https://zookeeper.apache.org/releases.html

2、修改配置文件并启动

解压后：

在conf文件夹下面将zoo.sample.cfg修改为zoo.cfg文件，

然后到bin目录下，启动zkServer.cnd就可以了

看一下zkEnv.cmd文件，这也是为什么刚才要修改为zoo.cfg文件，因为这里默认找的那个文件，所以你换成其他文件名也可以，只要和这里对应就行

启动成功，默认端口2181

安装dubbo-admin（注册中心的可视化管理平台）

1、下载dubbo-admin

https://gitee.com/shyf2019/dubbo-admin

image.png
如果熟悉git，也可以用git命令下载，这个也是从github上面复制过来的

2、导入eclipse

因为它是maven项目，所以导入一个maven项目到eclipse，等待下载好他的依赖

3、修改配置文件，主要是zookerper地址

4.启动项目后看效果

访问localhost:7001

服务注册

写一个member服务，注册到zookerper上面

1、聚合项目member的目录结构

image.png

父模块member两个子模块api和server

2、父模块member

pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.2.RELEASE</version>
    </parent>

2、api模块

image.png

在api模块中就一个接口

3、server模块

image.png

pom.xml

<dependencies>
        <dependency>
            <groupId>com.shyf.dubboA</groupId>
            <artifactId>api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.spring.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>2.0.0</version>
        </dependency>
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.10</version>
        </dependency>
    </dependencies>

application.yml

server:
  port: 9091
spring:
  dubbo:
    scan:
      basePackages: com.shyf.service
    application:
      id: member-service
      name: member-service
    protocol:
      id: dubbo
      name: dubbo
      port: 12345
    registry:
      id: my-registry
      address: zookeeper://127.0.0.1:2181

MemberServerImpl.java

import org.springframework.stereotype.Component;
import com.alibaba.dubbo.config.annotation.Service;
@Service
@Component
public class MemberServiceIMpl implements MemberService{
    @Override
    public String getMember(String s) {
        return "hello "+s;
    }
}

启动类MemberApp.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;

@SpringBootApplication
@ComponentScan("com.shyf")
@EnableDubboConfiguration
public class MemberApp {
    public static void main(String[] args) {
        SpringApplication.run(MemberApp.class, args);
    }
}

4、启动server子模块

查看dubbo-admin

5、发布api模块

在dubbo中，服务的消费者需要依赖，服务生产者的服务接口
maven install api

image.png

服务调用

创建一个order项目，maven项目，作为服务的消费者

1、项目目录

image.png

2、pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
    </parent>
    <dependencies>
        <dependency>
            <groupId>com.shyf.dubboA</groupId>
            <artifactId>api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.spring.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>2.0.0</version>
        </dependency>
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.10</version>
        </dependency>
    </dependencies>

3、application.yml

server:
  port: 9093

4、spring-dubbo.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://code.alibabatech.com/schema/dubbo
       http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <dubbo:application id="member-service" name="member-service"/>
    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
    <dubbo:protocol id="dubbo" name="dubbo" port="12345"/>
    <dubbo:reference id="memberService" interface="com.shyf.service.MemberService"  />
</beans>

5、OrderController.java

@RestController
public class OrderController {
    @Autowired
    private MemberService memberService;
    @RequestMapping("/getOrder")
    public Object getOrder(){
        return memberService.getMember("ly");
    }
}

6、启动类OrderApp.java

@SpringBootApplication
@EnableDubboConfig
@ImportResource(locations={"spring-dubbo.xml"})
public class OrderApp {
    public static void main(String[] args) {
        SpringApplication.run(OrderApp.class, args);
    }
}

7、启动
