#liteFlow
|
||||
轻量级的组件式流程框架
|
||||
### 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);
|
||||
```
