1 dubbo的 作用
以下内容摘自dubbo官网： dubbo是一款高性能、轻量级的开源Java RPC框架，它提供了三大核心能力：面向接口的远程方法调用，智能容错和负载均衡，以及服务自动注册和发现;2 查看官网大坑
(二)dubbo管理控制台的搭建git clone https://github.com/apache/incubator-dubbo-ops
cd incubator-dubbo-ops && mvn package
用法，分为三个 admin, register/ monitor
dubbo admin Dubbo admin is a spring boot application, you can start it with fat jar or in IDE directly.进入 dubbo-admin,执行 mvn install
----------------------------- maven 下载打包时需要配置 仓库MAVEN_HOME,Path=xxxxxj,这样的话就会用配置的阿里云镜像，下载会很快 碰到了不能编译，需要配置java环境变量 编译后启动报错了，因为没改zookeeper的配置ip,重新安装打包，运行target下的 java -jar dubbo-xxxxxx.jar，账号参考配置里的 root/root 或者 guest/xxxx,端口查看配置 时 7001
dubbo monitor and dubbo registry You can get a release of dubbo monitor in two steps: Step 1: git clone https://github.com/apache/incubator-dubbo-ops Step 2: cd incubator-dubbo-ops && mvn package Then you will find:
dubbo-monitor-simple-2.0.0-assembly.tar.gz in incubator-dubbo-ops\dubbo-monitor-simple\target directory. Unzip it you will find the shell scripts for starting or stopping monitor.
dubbo-registry-simple-2.0.0-assembly.tar.gz in incubator-dubbo-ops\dubbo-registry-simple\target directory. Unzip it you will find the shell scripts for starting or stopping registry. 
2 然后时健康检测项目，打包，改zookeeperip，解压生成的 target下的 xxx.gz,进入 assembly.bin，运行start.bat即可
F:\programme\dubbo-admin-master\dubbo-monitor-simple\target\dubbo-monitor-simple-2.0.0\assembly.bin
bat启动文件
f:
cd F:\programme\dubbo-admin-master\dubbo-admin\targetjava -jar dubbo-admin-0.0.1-SNAPSHOT.jarf:
cd F:\programme\dubbo-admin-master\dubbo-monitor-simple\target\dubbo-monitor-simple-2.0.0\assembly.binstart.bat
4 自动生成 serializable 方法的配置再idea中
4 真实的 测试dubbo的例子
/** * 订单服务相关接口 */public interface OrderService { /** * 初始化订单 * @param userId */ List initOrder(String userId);}public interface UserService { /** * 获取用户信息 * @param userId * @return */ List getUserList(String userId); List getUserAddressList(String userId); } user-service-provider com.darling.dubboDemo pub-interfence 1.0-SNAPSHOT com.alibaba dubbo 2.6.2 org.apache.curator curator-framework 2.12.0 package com.provider.userserviceprovider.service; import com.pubinter.pubinterface.dao.UserService; import com.pubinter.pubinterface.pojo.User; import java.util.ArrayList; import java.util.List; public class UserServiceImpl implements UserService { public List getUserAddressList(String userId) { List list = new ArrayList(); list.add(new User(3,"韦德",36,"迈阿密")); list.add(new User(23,"詹姆斯",34,"洛杉矶")); list.add(new User(24,"科比",39,"洛杉矶")); return list; } @Override public List getUserList(String userId) { return null; } } public class TestProviderDemo { public static void main(String[] args) throws IOException { // 加载配置文件 ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("provider.xml"); // 容器启动 applicationContext.start(); // 使程序阻塞(由于是单元测试,如果程序跑完了我们再dubbo控制台看不到效果) System.in.read(); } } 不启用spring boot 主类，因为没必要，只启动了这个一个配置文件 order-service-consumer com.darling.dubboDemo pub-interfence 1.0-SNAPSHOT com.alibaba dubbo 2.6.2 org.apache.curator curator-framework 2.12.0 /** * @author 董琳琳 * @date 2018/9/14 11:50 * @description 订单服务的实现类 */ @Service public class OrderServiceImpl implements OrderService { @Autowired UserService userService; /** * 初始化订单并调用用户服务的接口 * @param userId * @return */ @Override public List initOrder(String userId) { return userService.getUserAddressList(userId); } } user必须实现serializable接口 必须要加扫描路径，不然会出错，找不到类 list = service.initOrder("1"); for (User user:list) { System.out.println(user.toString()); } System.in.read(); } } import java.io.Serializable; public class User implements Serializable { private static final long serialVersionUID = -2844400681715908324L; private int age; private String name; private String address; private int number; User(){}; public User(int age,String name,int number,String address){ this.address=address; this.age=age; this.number=number; this.name=name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public int getNumber() { return number; } public void setNumber(int number) { this.number = number; } } 大概流程是，public 接口，有两个，一个user 类，需要实现serializable接口和 set get方法，第二个项目provider引入公共的刚才的想pub，进行生产者配置，第三个消费者配置，兜售ideal 项目的module方式，
最终的效果是
