dubbo入门-dubbo和springboot整合

接上篇dubbo入门-dubbo和spring整合，在上一个工程的基础上，进行修改，让dubbo和springboot实现整合

1.服务生产者模块：dubbo-demo-provider

• 在DemoServiceImpl上添加Service注解

package com.alibaba.dubbo.demo.provider;
import com.alibaba.dubbo.config.annotation.Service;
import com.alibaba.dubbo.demo.DemoService;

@Service(version = "1.0.0")
public class DemoServiceImpl implements DemoService {
    public String sayHello(String name) {
        return " I love you! " + name;
    }
}

• 将启动类修改为springboot的方式

package com.alibaba.dubbo.demo.provider;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Provider {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Provider.class, args);
    }
}

• pom文件添加springboot相关依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>dubbo-demo-provider</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>io.dubbo.springboot</groupId>
            <artifactId>spring-boot-starter-dubbo</artifactId>
            <version>1.0.0</version>
        </dependency>
        <dependency>
            <groupId>com.imooc</groupId>
            <artifactId>dubbo-demo-api</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

• 创建application.properties

##端口号
server.port=8880

## Dubbo 服务提供者配置
spring.dubbo.application.name=dubbo_provider
spring.dubbo.registry.address=multicast://224.5.6.7:1234
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.alibaba.dubbo.demo.provider

2.服务消费者模块：dubbo-demo-consumer

• 创建HelloController

package com.alibaba.dubbo.demo.consumer;

import com.alibaba.dubbo.config.annotation.Reference;
import com.alibaba.dubbo.demo.DemoService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @Reference(version = "1.0.0")
    DemoService demoService;

    @GetMapping("sayHello")
    public String sayHello(String name){
        return demoService.sayHello(name);
    }
}

• 创建入口类

package com.alibaba.dubbo.demo.consumer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Consumer {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Consumer.class,args);
    }
}

• 创建application.properties

## 端口号
server.port=8881

##Dubbo  服务消费者配置
spring.dubbo.application.name=dubbo_consumer
spring.dubbo.registry.address=multicast://224.5.6.7:1234
spring.dubbo.scan=com.alibaba.dubbo.demo.consumer
