钝化程序模式SOA架构BPM

在SOA架构中，通常都会存在着N多个服务接口，每个服务接口的消费者有着明确的角色定义，通过将一系列的服务接口串联起来就可以组成一个完整的业务流程，这也被称为业务流程管理（Business Process Manager）。那么扮演关业务流程管理的这段逻辑角色要能够支持多地区调用，某个业务内的流程管理器所要面对的是这个业务内的所有要参与其中的角色，每个角色调用不同的服务方法，但彼此又是相互影响的。

BPM每个阶段产生的数据都将作为下一个阶段需要输入的数据，将多个完本独立的SOA接口组成一个可以用来产生实际业务价值的业务功能块，这也是实施SOA（面向服务的体系结构-Service-Oriented Architecture）架构的价值之一。

钝化模式绝对是BPM框架的核心模式之一，下面我们就提供一个订单审批流程管理器

订单审批流程共需3个角色参与：
1.信息员检查订单
2.业务经理确认
3.总经理最终确认签字
