# 快速开始
|

liteflow需要你的项目使用maven
|
||
## 依赖
|
||
```xml
|
||
<dependency>
|
||
<groupId>com.thebeastshop.liteflow</groupId>
|
||
<artifactId>liteflow</artifactId>
|
||
<version>${liteFlow.version}</version>
|
||
</dependency>
|
||
```
|
||
## 流程配置文件
|
||
```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"/>
|
||
</nodes>
|
||
|
||
<chain name="demoChain">
|
||
<then value="a,b,c"/> <!-- then表示串行 -->
|
||
<when value="d,e"/> <!-- when表示并行 -->
|
||
</chain>
|
||
</flow>
|
||
```
|
||
|
||
component为组件，这里你需要实现这些组件，每个组件继承`NodeComponent`类
|
||
```java
|
||
public class AComponent extends NodeComponent {
|
||
|
||
@Override
|
||
public void process() {
|
||
String str = this.getSlot().getRequestData();
|
||
System.out.println(str);
|
||
System.out.println("Acomponent executed!");
|
||
}
|
||
}
|
||
```
|
||
|
||
chain为流程链，每个链上可配置多个组件节点。目前执行的模式分串行和并行2种。
|
||
串行标签为`then`，并行标签为`when`。
|
||
在串行的模式下，以下2种写法是等价的,可以根据业务需要来把不同种类的节点放一行里。
|
||
```xml
|
||
<then value="a,b,c,d"/>
|
||
```
|
||
```xml
|
||
<then value="a,b"/>
|
||
<then value="c,d"/>
|
||
```
|
||
|
||
## 执行流程链
|
||
```java
|
||
FlowExecutor executor = new FlowExecutor();
|
||
executor.setRulePath(Arrays.asList(new String[]{"/config/flow.xml"}));
|
||
executor.init();
|
||
Slot slot = executor.execute("demoChain", "arg");
|
||
```
|
||
