前面省略，直奔主题
3.Dubbox框架
3.1 Dubbox简介
Dubbox 是一个分布式服务框架，其前身是阿里巴巴开源项目Dubbo ，被国内电商及互联网项目中使用，后期阿里巴巴停止了该项目的维护，当当网便在Dubbo基础上进行优化，并继续维护，为了与原有的Dubbo区分，故将其命名为Dubbox。
Dubbox 致力于提供高性能和透明化的RPC远程服务调用方案，以及SOA服务治理方案。简单的说，dubbox就是个服务框架，如果没有分布式的需求，其实是不需要用的，只有在分布式的时候，才有dubbox这样的分布式服务框架的需求，并且本质上是个服务调用的东东，说白了就是个远程服务调用的分布式框架。
节点角色说明：
· Provider: 暴露服务的服务提供方。
· Consumer: 调用远程服务的服务消费方。
· Registry: 服务注册与发现的注册中心。
· Monitor: 统计服务的调用次数和调用时间的监控中心。
· Container: 服务运行容器。
调用关系说明：
· 0. 服务容器负责启动，加载，运行服务提供者。
· 1. 服务提供者在启动时，向注册中心注册自己提供的服务。
· 2. 服务消费者在启动时，向注册中心订阅自己所需的服务。
· 3. 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。
· 4. 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。
· 5. 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。
配置linux镜像：安装VM后双击此文件挂起品优购服务器
导入的虚拟机必须设置 ip 为 192.168.25.168 才可以使用 FastDFS(后面的课程会
用)；如果虚拟机不是 25 网段，需要手动设置网段，
打开虚拟机
帐号：root，密码：itcast
3.2注册中心Zookeeper
3.2.1 Zookeeper 介绍
官方推荐使用 zookeeper 注册中心。注册中心负责服务地址的注册与查找，相当于目录服务，服务提供者和消费者只在启动时与注册中心交互，注册中心不转发请求，压力较小。
Zookeeper 是 Apacahe Hadoop 的子项目，是一个树型的目录服务，支持变更推送，适合作为Dubbox 服务的注册中心，工业强度较高，可用于生产环境。
3.2.2 Zookeeper 在Linux系统的安装
安装步骤：
第一步：安装 jdk（此步省略，我给大家提供的镜像已经安装好JDK）
第二步：把 zookeeper 的压缩包（资源配套软件dubboxzookeeper-3.4.6.tar.gz）上传到 linux 系统。
第三步：解压缩压缩包
|
tar -zxvf zookeeper-3.4.6.tar.gz
|
第四步：进入 zookeeper-3.4.6 目录，创建 data 文件夹，放zookeeper注册数据。
第五步：进入conf目录 ，把 zoo_sample.cfg 改名为 zoo.cfg
|
cd conf
mv zoo_sample.cfg zoo.cfg
|
第六步：打开zoo.cfg , 修改 data 属性：dataDir=/root/zookeeper-3.4.6/data
vim zoo.cfg
点击i 进入插入模式
点击ESC 然后 :wq保存并退出
3.2.3 Zookeeper 服务启动
进入bin目录，启动服务输入命令
cd ..
cd bin
输出以下内容表示启动成功
关闭服务输入命令
输出以下提示信息
查看状态：
如果启动状态，提示
如果未启动状态，提示：

（2）在工程的webapps下创建WEB-INF文件夹，创建web.xml
|
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0"
metadata-complete="false">
<!-- 加载spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
|
|
添加：
|
（3）创建业务接口
创建包cn.gdut.dubbodemo.service，用于存放业务接口，创建接口
|
package cn.gdut.dubbodemo.service;
public interface UserService {
public String getName();
}
|
（4）创建业务实现类
创建包cn.gdut.dubbodemo.service.impl，用于存放业务实现类。创建业务实现类：
|
package cn.gdut.dubbodemo.service.impl;
import cn.gdut.dubbodemo.service.UserService;
import com.alibaba.dubbo.config.annotation.Service;
@Service
public class UserServiceImpl implements UserService {
public String getName() {
return "itcast";
}
}
|
注意：Service注解与原来不同，需要引入com.alibaba包下的，不然服务不能注册到注册中心
（5）编写配置文件
在src/main/resources下创建applicationContext-service.xml ,内容如下：
|
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<dubbo:application name="dubbodemo-service"/>
<dubbo:registry address="zookeeper://192.168.25.131:2181"/>
<dubbo:annotation package="cn.gdut.dubbodemo.service.impl" />
</beans>
|
注意：dubbo:annotation用于扫描@Service注解。
（6）测试运行
3.5.2服务消费者开发
开发步骤：
（1）创建Maven工程（WAR）dubboWeb ，在pom.xml引入依赖 ，同“dubboService”工程。区别就是把tomcat插件的运行端口改为8082 。
（2）在webapps目录下创建WEB-INF 目录，并创建web.xml
|
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0"
metadata-complete="false">
<!-- 解决post乱码 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 指定加载的配置文件 ，通过参数contextConfigLocation加载-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-web.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
|
（3）拷贝业务接口
将“dubboService”工程的cn.gdut.dubbodemo.service 包以及下面的接口拷贝至此工程。
注意实现类 impl包不要拷贝
（4）编写Controller
|
package cn.gdut.dubbodemo.controller;
import cn.gdut.dubbodemo.service.UserService;
import com.alibaba.dubbo.config.annotation.Reference;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping("/user")
public class UserController {
@Reference
private UserService userService;
@RequestMapping("/showName")
@ResponseBody
public String showName(){
return userService.getName();
}
}
|
（5）编写spring配置文件
在src/main/resources下创建applicationContext-web.xml
|
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!--SpringMvc的转换器，可以把返回值转换成字符串-->
<mvc:annotation-driven >
<mvc:message-converters register-defaults="false">
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8" />
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!-- 引用dubbo 服务 -->
<dubbo:application name="dubboxdemo-web" />
<dubbo:registry address="zookeeper://192.168.25.131:2181"/>
<dubbo:annotation package="cn.gdut.dubbodemo.controller" />
</beans>
|
（6）测试运行
在浏览器输入http://localhost:8082/user/showName.do，查看浏览器输出结果
3.6管理中心的部署
我们在开发时，需要知道注册中心都注册了哪些服务，以便我们开发和测试。我们可以通过部署一个管理中心来实现。其实管理中心就是一个web应用，部署到tomcat即可。
3.6.1管理端安装
（1）编译源码，得到war包
给大家下发的资源中有个dubbox-master.zip ，这个是dubbox的源码，我们可以使用maven命令编译源码得到“管理端”的war包
将此压缩包解压，在命令符下进入dubbo-admin目录 ，输入maven命令
|
mvn package -Dmaven.skip.test=true
|
|
|
如果你看到如下信息，就说明成功了
（2）进入target文件夹，你会看到一个dubbo-admin-2.8.4.war ，改名为dubbo-admin.war 把它和tomcat传到linux里面：
3.在linux服务器上解压tomcat安装包, 将此dubbo-admin.war 移动到linux服务器的tomcat的webapps下。启动tomcat后会自动解压dubbo-admin.war 。
把dubbo-admin.war移动到webapps下
启动tomcat
（4）如果你部署在zookeeper同一台主机并且端口是默认的2181，则无需修改任何配置。如果不是在一台主机上或端口被修改，需要修改WEB-INF下的dubbo.properties ，修改如下配置：
|
dubbo.registry.address=zookeeper://127.0.0.1:2181
|
修改后重新启动tomcat
3.6.2管理端使用
（1）打开浏览器，输入http://192.168.25.131:8080/dubbo-admin/ ,登录用户名和密码均为root 进入首页。 (192.168.25.131)是我部署的linux主机地址。
（3）启动服务提供者和消费者工程，可以观察提供者和“消费者”列表
4.品优购-框架搭建
4.1工程结构分析与设计
工程说明：
pinyougou-parent 聚合工程
pinyougou-pojo 通用实体类层
pinyougou-dao 通用数据访问层
pinyougou-xxxxx-interface 某服务层接口
pinyougou-xxxxx-service 某服务层实现
pinyougou-xxxxx-web 某web工程
4.2创建数据库表
执行资源文件夹中pinyougou-db.sql
IDEA 开发环境设置
先创建一个空的工程用来组织其它模块
4.3搭建框架
最终完整的工程结构如下：
4.3.1父工程
品优购聚合父工程；包括后续开发的所有品优购聚合子工程。主要功能是进行依赖、插件统一管理。
创建Maven工程pinyougou-parent （POM） ，groupId 为com.pinyougou ,artifactId 为pinyougou-parent , 在pom.xml中添加锁定版本信息dependencyManagement与pluginManagement，详见“资源/配置文件/第一天搭建/父工程/pom.xml”。
以下模块均继承自此父工程
添加依赖（此处的依赖用于集中的定义版本号，后续的子模块不用在定义版本号。目的是统一所有模块依赖的版本号，管理起来比较方便）下面链接有详细的介绍
https://www.cnblogs.com/feibazhf/p/7886617.html
4.3.2通用实体类模块
实体类工程；统一放置品优购的所有数据库实体类或者其它模型
创建通用实体类模块pinyougou-pojo

4.3.8商家管理后台
构建web模块pinyougou-shop-web 与运营商管理后台的构建方式类似。Pom也类似，区别：
（1）定义tomcat的启动端口为9102
（2）springmvc.xml

把生成的代码拷贝到下面两个工程
然后 所有的pojo类，除了Example类，其它的全部实现序列化接口（代码生成器已经帮助生成了，不用我们生成了）

修改每个实体类，让其实现Serializable接口。因为需要不同网络间相互传数据： windows和linux
简单地说，就是可以将一个对象(标志对象的类型)及其状态转换为字节码，保存起来（可以保存在数据库，内存，文件等）,然后可以在适当的时候再将其状态恢复(也就是反序列化)。serialization 不但可以在本机做，而且可以经由网络操作。它自动屏蔽了操作系统的差异，字节顺序等。比如，在 Windows 平台生成一个对象并序列化之，然后通过网络传到一台 Unix 机器上，然后可以在这台Unix机器上正确地重构（deserialization）这个对象。 不必关心数据在不同机器上如何表示，也不必关心字节的顺序或者其他任何细节。
注意修改完毕要重新install pojo工程，否则不生效。以后修改完代码，都要重新install一下工程

5.3后端代码
5.2.1 服务层接口
在pinyougou-sellergoods-interface 工程创建BrandService接口
|
package com.pinyougou.sellergoods.service;
import java.util.List;
import com.pinyougou.pojo.TbBrand;
/**
* 品牌服务层接口
* @author Administrator
*
*/
public interface BrandService {
/**
* 返回全部列表
* @return
*/
public List<TbBrand> findAll();
}
|
|
|
5.2.2 服务实现类
在pinyougou-sellergoods-service 工程创建BrandServiceImpl类
|
package com.pinyougou.sellergoods.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import com.alibaba.dubbo.config.annotation.Service;
import com.pinyougou.mapper.TbBrandMapper;
import com.pinyougou.pojo.TbBrand;
import com.pinyougou.sellergoods.service.BrandService;
@Service
public class BrandServiceImpl implements BrandService {
@Autowired
private TbBrandMapper brandMapper; //需要添加数据访问层依赖
@Override
public List<TbBrand> findAll() {
return brandMapper.selectByExample(null);
}
}
|
5.2.3 控制层代码
在pinyougou-manager-web工程创建com.pinyougou.manager.controller包，包下创建BrandController类
|
package com.pinyougou.manager.controller;
import java.util.List;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.alibaba.dubbo.config.annotation.Reference;
import com.pinyougou.pojo.TbBrand;
import com.pinyougou.sellergoods.service.BrandService;
/**
* 品牌controller
* @author Administrator
*/
@RestController
@RequestMapping("/brand")
public class BrandController {
@Reference
private BrandService brandService;
/**
* 返回全部列表
* @return
*/
@RequestMapping("/findAll")
public List<TbBrand> findAll(){
return brandService.findAll();
}
}
|
5.4测试
启动pinyougou-sellergoods-service
启动pinyougou-manager-web
地址栏输入http://localhost:9101/brand/findAll.do
出错的地方
1 spring的版本和其它jar包的版本有冲突报错java.lang.NoSuchMethodError: org.springframework.beans.factory.annotation.InjectionMetadata.

2 PageHelper connot be cast to org.apache.ibatis.plugin.Interceptor
PageHelper 的版本和配置文件的配置方式不匹配

3.出现了这个问题耽误了两天！！！！！！！！！！！！！！！！
原因
classpath和classpath*区别： https://www.cnblogs.com/EasonJim/p/6709314.html
classpath：只会到你的class路径中查找找文件。
classpath*：不仅包含class路径，还包括jar文件中（class路径）进行查找。
注意： 用classpath*:需要遍历所有的classpath，所以加载速度是很慢的；因此，在规划的时候，应该尽可能规划好资源文件所在的路径，尽量避免使用classpath*。
classpath*的使用：
当项目中有多个classpath路径，并同时加载多个classpath路径下（此种情况多数不会遇到）的文件，*就发挥了作用，如果不加*，则表示仅仅加载第一个classpath路径。
此外，web的spingmvc配置文件中要添加消息转换器
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.StringHttpMessageConverter" />
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
</mvc:message-converters>
</mvc:annotation-driven>
否则
不能返回ArrayList
最后
可以看到浏览器输出了json数据。
附录：常见错误
1.在注册中心找不到对应的服务
|
java.lang.IllegalStateException: Failed to check the status of the service com.pinyougou.sellergoods.service.BrandService. No provider available for the service com.pinyougou.sellergoods.service.BrandService from the url zookeeper://192.168.25.129:2181/com.alibaba.dubbo.registry.RegistryService?application=pinyougou-manager-web&dubbo=2.8.4&interface=com.pinyougou.sellergoods.service.BrandService&methods=update,get,delete,selectOptionList,add,getListByPage&pid=3980&revision=0.0.1-SNAPSHOT&side=consumer×tamp=1501146823396 to the consumer 172.16.17.14 use dubbo version 2.8.4
|
这种错误是服务层代码没有成功注册到注册中心导致，请检查一下你的服务层代码是否添加了@service注解，并且该注解的包一定是com.alibaba.dubbo.config.annotation包，不是org.springframework.stereotype.Service，这个地方极容易出错。另外还有一个原因就是你的服务层工程由于某些原因没有正常启动，也无法注册到注册中心里。
2.无法连接到注册中心
|
org.I0Itec.zkclient.exception.ZkTimeoutException: Unable to connect to zookeeper server within timeout: 5000 org.I0Itec.zkclient.ZkClient.connect(ZkClient.java:876) org.I0Itec.zkclient.ZkClient.<init>(ZkClient.java:98) org.I0Itec.zkclient.ZkClient.<init>(ZkClient.java:92) org.I0Itec.zkclient.ZkClient.<init>(ZkClient.java:80)
com.alibaba.dubbo.remoting.zookeeper.zkclient.ZkclientZookeeperClient.<init>(ZkclientZookeeperClient.java:26)

请检查IP与端口是否填写正确，检查注册中心是否正常启动
