注：本教程环境为mac os
1：安装zookeeper
brew install zookeeper
启动：
zkServer start
2：安装dubbox
git clone https://github.com/dangdangdotcom/dubbox.git
mvn install -Dmaven.test.skip=true
3：IDEA建立spring-boot程序
new project -> Spring Initializr
其它按照ide步骤提示即可
4：pom.xml dependency
4：配置dubbo
package com.example.config;
import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.ProtocolConfig;
import com.alibaba.dubbo.config.RegistryConfig;
import com.alibaba.dubbo.config.spring.AnnotationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* Created by yhon on 2017/5/8.
*/
@Configuration
public class DubboConfig {
public static final String APPLICATION_NAME="provider-hello";
public static final String REGISTRY_ADDRESS="zookeeper://127.0.0.1:2181";
public static final String ANNOTATION_PACKAGE="com.example.provider";
@Bean
public ApplicationConfig applicationConfig() {
ApplicationConfig applicationConfig =newApplicationConfig();
applicationConfig.setName(APPLICATION_NAME);
returnapplicationConfig;
}
@Bean
public RegistryConfig registryConfig() {
RegistryConfig registryConfig =newRegistryConfig();
registryConfig.setAddress(REGISTRY_ADDRESS);
returnregistryConfig;
}
@Bean
public ProtocolConfig protocolConfig() {
ProtocolConfig protocolConfig =newProtocolConfig();
protocolConfig.setName("dubbo");
protocolConfig.setPort(20880);
returnprotocolConfig;
}
@Bean
public static AnnotationBean annotationBean() {
AnnotationBean annotationBean =newAnnotationBean();
annotationBean.setPackage(ANNOTATION_PACKAGE);
returnannotationBean;
}
}
5：服务端
接口编写：
package com.example.provider;
/**
* Created by yhon on 2017/5/8.
*/
public interface HelloService {
String sayHello();
}
service编写：
package com.example.provider;
import com.alibaba.dubbo.config.annotation.Service;
/**
* Created by yhon on 2017/5/8.
*/
@Service(version="0.0.1")
public class HelloServiceImp implements HelloService{
@Override
public String sayHello() {
return"hello word";
}
}
6：消费端
消费端配置和服务端类似，只需修改ANNOTATION_PACKAGE = "com.example.service"
客户端调用代码：
package com.example.service;
import com.alibaba.dubbo.config.annotation.Reference;
import com.example.provider.HelloService;
import com.fasterxml.jackson.core.JsonProcessingException;
import org.springframework.stereotype.Service;
/**
* Created by yhon on 2017/5/9.
*/
@Service
public class HelloServiceImp {
@Reference(version="0.0.1")
private HelloService helloService;
public String sayHello(){
return helloService.sayHello();
}
}
7：消费端编写接口测试
接口代码：
package com.example;
import com.example.service.HelloServiceImp;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
import java.util.Map;
@SpringBootApplication
@RestController
public class DubboCustApplication {
@Autowired
private HelloServiceImp helloServiceImp;
@RequestMapping(value="/hello",method= RequestMethod.GET)
public Map getHello(){
String status =helloServiceImp.sayHello();
Map map =newHashMap<>();
map.put("message",status);
return map;
}
public static voidmain(String[] args) {
SpringApplication.run(DubboCustApplication.class,args);
}
}
至此浏览器中输入 127.0.0.1:8080/hello 即可得到如下字符串
{"status":"hello word"}
