dubbo入门学习
官方网址：http://dubbo.apache.org/zh-cn/index.html
学习可以参考官网中文文档：http://dubbo.apache.org/zh-cn/docs/user/quick-start.html
SOA，英文名称(Service Oriented Ambiguity)，中文名称:面向服务架构（有一个专门提供服务单元，其他所有单元都调用这个服务）。SOA专门访问数据库服务(项目)，开发时可以实现,数据访问控制和代码复用。
实现SOA架构时,常用服务：
a、Dubbo 做为服务。
b、WebService 做为服务。
c、Dubbox 做为服务。
d、服务方就是web项目,调用web项目的控制器。
使用HttpClient可以调用其他项目的控制器。
RPC，英文名称(Remote Procedure Call Protocol)，中文名称:远程过程调用协议，RPC解析:客户端(A)通过互联网调用远程服务器,不知道远程服务器具体实现,只知道远程服务器提供了什么功能。RPC最大优点，数据安全性。
1、Apache 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。Dubbo一个分布式、高性能、透明化的RPC服务框架。作用是，提供服务自动注册、自动发现等高效服务治理方案
如果项目表现层、服务层是不同的项目，可以使用dubbo实现两个系统之间的通信。服务层和表现层相互通信，使用dubbo中间件，让表现层调用服务层。工程之间的相互通信可以使用dubbo,，可以统一管理服务，系统之间的调用。
如何实现远程通信。
、Webservice，效率不高，基于soap协议，项目中不推荐使用。
、使用restful形式的服务，http+json，很多项目中应用。如果服务太多，服务之间的调用关系混乱，需要治疗服务。
、dubbo，使用rpc协议进行远程调用，直接使用socket通信，传输效率高，并且可以统计出系统之间的调用关系，调用次数。缺点，由于是java开发，只能是两个java项目进行调度。
2、dubbo架构。术语来自官网。可以直接查看官网。
虚线都是异步访问,实线都是同步访问。
蓝色虚线:在启动时完成的功能。
红色虚线(实线)都是程序运行过程中执行的功能。
所有的角色都是可以在单独的服务器上.所以必须遵守特定的协议。
节点角色说明
| 节点 | 角色说明 |
|---|---|
Provider |
暴露服务的服务提供方，提供者,服务发布方 |
Consumer |
调用远程服务的服务消费方，消费者, 调用服务方 |
Registry |
服务注册与发现的注册中心，注册中心.当Container启动时把所有可以提供的服务列表上Registry中进行注册，作用:告诉Consumer提供了什么服务和服务方在哪里 |
Monitor |
统计服务的调用次数和调用时间的监控中心，监听器 |
Container |
服务运行容器，Dubbo容器.依赖于Spring容器 |
调用关系说明
- 服务容器负责启动，加载，运行服务提供者。
- 服务提供者在启动时，向注册中心注册自己提供的服务。
- 服务消费者在启动时，向注册中心订阅自己所需的服务。
- 注册中心返回服务提供者地址列表给消费者，如果有变更，注册中心将基于长连接推送变更数据给消费者。
- 服务消费者，从提供者地址列表中，基于软负载均衡算法，选一台提供者进行调用，如果调用失败，再选另一台调用。
- 服务消费者和提供者，在内存中累计调用次数和调用时间，定时每分钟发送一次统计数据到监控中心。
Dubbo 架构具有以下几个特点，分别是连通性、健壮性、伸缩性、以及向未来架构的升级性。
. Dubbo运行原理:
2.0 启动容器,相当于在启动Dubbo的Provider
2.1 启动后会去注册中心进行注册.注册所有可以提供的服务列表
2.2 在Consumer启动后会去Registry中获取服务列表和Provider的地址.进行订阅.
2.3 当Provider有修改后,注册中心会把消息推送给Consummer
2.3. 使用了观察者设计模式(又叫发布/订阅设计模式)
2.4 根据获取到的Provider地址,真实调用Provider中功能.
2.4. 在Consumer方使用了代理设计模式.创建一个Provider方类的一个代理对象.通过代理对象获取Provider中真实功能,起到保护Provider真实功能的作用.
2.5 Consumer和Provider每隔1分钟向Monitor发送统计信息,统计信息包含,访问次数,频率等.
3、注册中心（推荐zookeeper，也可以使用redis的呢）
注册中心负责服务地址得注册与查找，相当于目录服务，服务提供者和消费者只在启动得时候与注册中心交互，注册中心不转发请求，压力较小，使用dubbo2.3.3以上版本，建议使用zookeeper注册中心。zookeeper是一个树形的目录服务，支持变更推送，适合作为dubbo服务的注册中心，工业强度高，可以用于生产环境，推荐使用。
4、安装zookeeper，必须首先安装jdk，这里安装jdk1.7版本。首先将安装包上传到机器上面哦。
[root@localhost jdk1.7.0_55]# tar -zxvf jdk-7u55-linux-i586.tar.gz -C /home/hadoop/soft
[root@localhost ~]# vim /etc/profile
export JAVA_HOME=/home/hadoop/soft/jdk1..0_55
export PATH=$PATH:$JAVA_HOME/bin
[root@localhost ~]# source /etc/profile
[root@localhost ~]# java
[root@localhost ~]# javac
[root@localhost ~]# java -version
5、开始安装zookeeper，首先将安装包上传到机器上面哦。
解压缩操作哦。
[root@localhost package]# tar -zxvf zookeeper-3.4.6.tar.gz -C /home/hadoop/soft/
然后配置一下zookeeper，就可以启动zookeeper了。
首先创建一个data文件夹。
配置完成了，就可以启动zookeeper。进行验证是否可以正常启动。
[root@localhost bin]# ./zkServer.sh start
JMX enabled by default
Using config: /home/hadoop/soft/zookeeper-3.4./bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /home/hadoop/soft/zookeeper-3.4./bin/../conf/zoo.cfg
Mode: standalone
[root@localhost bin]#
[root@localhost bin]# ./zkServer.sh start 启动
[root@localhost bin]# ./zkServer.sh status 查看启动状态
[root@localhost bin]# ./zkServer.sh stop 关闭
注意：为了外部可以访问，可以将zookeeper的2181的端口号添加到防火墙可以访问。避免出现防火墙拒绝访问的情况出现。
[root@localhost ~]# vim /etc/sysconfig/iptables
然后，重启防火墙，[root@localhost ~]# service iptables restart。或者你直接将防火墙关闭也可以，视自己的情况而定吧。
6、zookeeper安装成功以后，就可以操作，服务如何发布，客户端如何引用服务。
Dubbo采用全Spring配置方式，透明化接入应用，对应用没有任何api侵入，只需要用spring加载dubbo的配置即可，dubbo基于spring的schema扩展进行加载。
远程服务。在本地服务的基础上，只需要简单的配置，即可以完成远程话。
将传统写的xml配置文件中的bean注入以及bean的依赖注入的配置拆分成两份，将服务定义部分放在服务提供方remote-provider.xml，将服务引用部分放在服务消费方remote-consumer.xml配置文件中。并在提供方增加暴漏服务配置<dubbo:service>，在消费方增加引用服务配置<dubbo:reference>。官网截图：
7、发布dubbo服务。定义一个接口。
package com.taotao.service; import com.taotao.pojo.TbItem; /**
*
* @ClassName: ItemService.java
* @author: biehl
* @since: 2019年8月2日 下午3:32:36
* @Copyright: ©2019 biehl 版权所有
* @version: 0.0.1
* @Description:商品接口类
*
*/
public interface ItemService { /**
* 根据itemId查询出商品信息
*
* @param itemId
* @return
*/
public TbItem getItemById(long itemId); }
定义实现接口的实现类。
package com.taotao.service.impl; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils; import com.taotao.mapper.TbItemMapper;
import com.taotao.pojo.TbItem;
import com.taotao.service.ItemService; /**
*
* @ClassName: ItemServiceImpl.java
* @author: biehl
* @since: 2019年8月2日 下午3:51:24
* @Copyright: ©2019 biehl 版权所有
* @version: 0.0.1
* @Description: 商品实现类
*/
@Service
public class ItemServiceImpl implements ItemService { @Autowired
private TbItemMapper tbItemMapper; @Override
public TbItem getItemById(long itemId) {
TbItem tbItem = new TbItem();
if (!StringUtils.isEmpty(itemId)) {
tbItem = tbItemMapper.selectByPrimaryKey(itemId);
}
// 返回信息以后就可以发布服务
return tbItem;
} }
配置提供dubbo的服务。

@Controller
public class ItemController { // itemService就是dubbo配置的id="itemService"
@Autowired
private ItemService itemService; @RequestMapping(value = "/item/{itemId}")
@ResponseBody
public TbItem getItemById(@PathVariable(value = "itemId") Long itemId) {
TbItem tbItem = new TbItem();
tbItem = itemService.getItemById(itemId);
return tbItem;
} }
9、dubbo服务调用测试。记得关闭dubbo服务器的防火墙，不然急死你。
访问http://localhost:8081/item/536563，报错了，然后呢，解决问题呗。是因为mapper映射文件没有发布的问题。在工程的pom配置文件里面添加如下配置内容。

为解决问题的时候，只有接口，没有对应的配置SQL文件。
在pom配置文件里面添加如下配置即可。默认是将src/main/resources目录下面的文件放到\target\classes\目标目录下面，现在修改默认配置，将src/main/java目录下面的文件放到\target\classes\目标目录下面。
<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉的。 -->
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
<!-- <resource> 如果需要复制resources下面的文件，需要添加此配置即可
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource> -->
</resources>
</build>
然后重启dubbo的发布服务。dubbo的应用服务可以不用重启，表现层只需要调用服务即可。然后又报了下面这个错误。聚合工程下面的模块修改了，也不需要安装，因为你启动的是聚合工程，所以直接启动聚合工程即可。

报这种序列号的错误，是实体类必须实现序列化接口，将查询出的数据必须进行序列化，才可以进行传输。将服务层的序列化的数据传递给表现层（客户端），然后表现层进行反序列化即可。里面的实体类，除了example的都实现序列化即可。
由于表现层在表现层可能会用到，所以将pojo安装一下。就可以了。
最后重启dubbo的提供服务，然后重启dubbo的引用服务。终于出现数据了。
10、dubbo的监控中心。dubbo-admin-2.5.4.war项目包运行起来就可以监控了。和安装zookeeper的机器放到一起就可以直接起到监控效果了。
安装你的tomcat。然后将dubbo的war包部署到tomcat里面即可。
[root@localhost package]# tar -zxvf apache-tomcat-7.0.47.tar.gz -C /home/hadoop/soft/
将dubbo的war包部署到tomcat的webapps里面即可。
[root@localhost soft]# cp dubbo-admin-2.5.4.war apache-tomcat-7.0.47/webapps/dubbo-admin.war
然后启动你的tomcat。
