### 概述
liteFlow是一个轻量级的组件式流程框架帮助解耦业务代码让每一个业务片段都是一个组件
* 提供本地xml的流程配置。
* 提供串行和并行2种模式。
* 引入classfinder机制组件自动注册。
* 消除组件之间参数传递,引入数据总线概念。
* 自带简单的监控能够知道每个组件的运行平均时间。消耗内存。每隔10分钟会自动打印
### Quick Start
1. 定义组件需继承Component项目启动时会被自动发现。
2. 定义xml配置(例子)
```xml
<?xml version="1.0" encoding="UTF-8"?>
<flow>
<nodes>
<node id="a" class="com.thebeastshop.liteflow.test.component.AComponent"/>
<node id="b" class="com.thebeastshop.liteflow.test.component.BComponent"/>
<node id="c" class="com.thebeastshop.liteflow.test.component.CComponent"/>
<node id="d" class="com.thebeastshop.liteflow.test.component.DComponent"/>
<node id="e" class="com.thebeastshop.liteflow.test.component.EComponent"/>
<node id="f" class="com.thebeastshop.liteflow.test.component.FComponent"/>
<node id="g" class="com.thebeastshop.liteflow.test.component.GComponent"/>
</nodes>
<chain name="chain1">
<then value="a,c"/> <!-- then代表串行 -->
<when value="b,d"/> <!-- when代表并行 -->
<then value="e,f,g"/>
</chain>
<chain name="chain2">
<then value="a,c,g"/>
<when value="b,e"/>
<then value="d,f"/>
</chain>
</flow>
```
3.spring里声明执行器
```xml
<bean id="flowExecutor" class="com.thebeastshop.liteflow.core.FlowExecutor" init-method="init">
<property name="rulePath">
<list>
<value>flow.xml</value>
</list>
</property>
</bean>
```
4.开始一个流程
```java
executor.execute("chain2", 参数);
```
