使用SpringBoot+Dubbo搭建微服务笔记( 二 )

微服务

公共实体-People.java
package com.czh.dubbo.common.entity;import java.io.Serializable;public class People implements Serializable { /** **/ private static final long serialVersionUID = 1415852192397895853L; // 人员编号 private int id; // 姓名 private String name; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "People [id=" + id + ", name=" + name + "]"; }}公共服务接口-PeopleService.java
package com.czh.dubbo.common.service;import com.czh.dubbo.common.entity.People;public interface PeopleService { People getPeople(People people);}五、搭建服务提供者服务提供者就是被消费者所调用的，它需要实现公共服务接口，并通过dubbo把自己的服务暴露出来 。

application.properties
#web服务端口，由于我们不需要使用web服务，所以将其设为随机端口server.port=-1#dubbo服务端口，我们无需知道dubbo服务运行在哪个端口，故也将其设为随机端口dubbo.protocol.port = -1#dubbo服务名称dubbo.application.name = dubbo-provider#dubbo服务所在包路径dubbo.scan.basePackages = com.czh.dubbo.provider.service#注册中心地址dubbo.registry.address=zookeeper://127.0.0.1:2181#设置服务的日志输出级别为debug级logging.level.com.czh.dubbo.provider.service=debug服务实现类PeopleServiceImpl
