SOA分布式架构搭建(dubbo)
一、分布式架构的演进
1.单一应用架构
- 优点：适用于小型网站，小型管理系统，将所有功能都部署到一个功能里，简单易用。
- 缺点： 1.性能扩展比较难 2.协同开发问题 3.不利于升级维护
2.垂直应用架构
javascript:void(0);
- 优点：通过切分业务来实现单个模块单独独立部署，降低了维护和部署的难度，团队各司其职比较容易，性能扩展也更方便，更有针对性。
- 缺点：公用模块无法重复利用，开发性能浪费
3.分布式应用架构
- 优点：将各个应用通过分层独立出来，可以利用rpc实现web与service、service与service的互相调用，提高了代码的复用性。
- 缺点：每个调用的模块都要存储一份完整的被调用模块的位置和状态，一旦位置和状态发生变化，就要更新所有涉及的配置
4.面向服务的分布式架构
架构概述：随着架构不断增大，服务节点也越来越多，服务之间的调用和依赖关系也越来越负责，需要一个统一的中心来调度、路由、管理所有的服务基于这个中心构建的这个新型架构就是目前主流的SOA分布式架构。
二、分布式工程的模块搭建
1、分布式模块文件图
由于查询web应用需要调用爬虫service接口，那么必须在订单的工程中也包含一份service接口。
如果拷贝一个接口道查询工程中，那么如果以后有更多的模块都调用这个接口呢？每个接口都拷贝一份嘛？
这种情况就可以利用maven的依赖把这些接口作为公共的包管理起来。同时接口类中的方法也引用了很多的实体bean，那么同样的实体bean类也可以统一管理起来。
2、分布式依赖关系图
3、分布式某块模块搭建
①创建parent模块
- 新建maven模块
- 定义模块名、包名
- parent模块中的 pom.xml
由于依赖包分布于多个模块中，最好有一个地方能够把所有依赖的版本管理起来。这里便可以使用maven中的<parent>概念。可以让所有的模块都继承这个parent模块，由这个parent模块来管理版本。</parent>

利用maven的依赖把这些接口作为公共的包管理起来。同时接口类中的方法也引用了很多的实体bean，那么同样的实体bean类也可以统一管理起来。

bean模块其中引用了通用mapper，所以我们把通用mapper的依赖提取出来放到bean模块后面，变成如下结构。
