Spring Boot 2.X - 整合Dubbo分布式框架

springboot2-dubbo-demo

• Desc:
  Spring Boot 2 整合 Dubbo 的一个小 Demo;

1. 创建一个Maven父工程springboot2-dubbo-demo：

以Intellij IDEA 为例:
File->New->Project-Maven,直接Next,
填写GroupId,ArtifactId;

Next->Finish.

2. 创建子模块:

在创建的父工程项目名字上右击New->Module-Maven(或者用Spring Initialize创建一个Spring Boot模块,然后再改);
创建三个Module,分别为:

springboot-dubbo-api	springboot-dubbo-provider	springboot-dubbo-consumer
存放API接口、Entity等	Dubbo服务提供者	Dubbo服务消费者、Web等

3. 修改项目pom文件结构;

4. 导入Dubbo依赖:

<dependency>
    <groupId>com.alibaba.bootgroupId>
    <artifactId>dubbo-spring-boot-starterartifactId>
    <version>0.2.0version>
dependency>

这里要注意版本要求:

versions	Java	Spring Boot	Dubbo
0.2.0	1.8+	2.0.x	2.6.2 +
0.1.1	1.7+	1.5.x	2.6.2 +

5. 定义API接口:

在springboot-dubbo-api模块中新增一个接口:

public interface DemoService {
    /**
     * say Hello.
     * @param name
     * @return
     */
    String sayHello(String name);
}

6. 提供Provider服务:

1-实现DemoService接口:

@Service // 注意这个是dubbo的service注解,com.alibaba.dubbo.config.annotation.Service
public class DemoServiceImpl implements DemoService {
    /**
     * say Hello.
     * @param name
     * @return
     */
    @Override
    public String sayHello(String name) {
        return "Hello, " + name + " (from Spring Boot)";
    }
}

2-在xxxApplication的启动类上标注@EnableDubbo,启用Dubbo配置
3-配置dubbo:

server.port=8081
dubbo.application.name=springboot-dubbo-provider
dubbo.application.version=1.0.0
dubbo.registry.address=zookeeper://localhost:2181 #这个为自己的zookeeper地址,默认开放端口2181
dubbo.provider.timeout=1000

配置完成,启动服务;

7. 编写消费者Consumer:

1-引入API依赖关系:

<dependency>
    <groupId>com.xudcgroupId>
    <artifactId>springboot-dubbo-apiartifactId>
    <version>0.0.1-SNAPSHOTversion>
dependency>

2-编写DemoController测试:

@RestController
public class DemoController {

    @Reference //用Dubbo提供的注解@Reference引入Spring Bean,com.alibaba.dubbo.config.annotation.Reference
    private DemoService demoService;

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

3-编写properties配置文件:

server.port=80
dubbo.application.name=springboot-dubbo-consumer
dubbo.application.version=1.0.0
dubbo.registry.address=zookeeper://localhost:2181
dubbo.consumer.timeout=1000

4-启动xxxApplication,浏览器输入http://localhost/hello?name=andy测试;
