Define your component

You need to define and implement some components to ensure that Spring will scan these components and register them in the context

@Component("a")
public class ACmp extends NodeComponent {

    @Override
    public void process() {
        //do your business
    }
}

And so on to define the b and c components:

@Component("b")
public class BCmp extends NodeComponent {

	@Override
	public void process() {
		//do your business
	}
}

@Component("c")
public class CCmp extends NodeComponent {

	@Override
	public void process() {
		//do your business
	}
}

Configuration in Spring xml

<context:component-scan base-package="com.yomahub.flowtest.components" />

<bean id="springAware" class="com.yomahub.liteflow.spi.spring.SpringAware"/>

<bean class="com.yomahub.liteflow.spring.ComponentScanner"/>

<bean id="liteflowConfig" class="com.yomahub.liteflow.property.LiteflowConfig">
    <property name="ruleSource" value="config/flow.el.xml"/>
</bean>

<bean id="flowExecutor" class="com.yomahub.liteflow.core.FlowExecutor">
    <property name="liteflowConfig" ref="liteflowConfig"/>
</bean>

<!-- If the above enableLog is false, the following config can also be omitted -->
<bean class="com.yomahub.liteflow.monitor.MonitorBus">
    <property name="liteflowConfig" ref="liteflowConfig"/>
</bean>

For more configuration items, please refer to the Configuration Items chapter.

Definition of rules file

You have to configure the following configuration in config/flow.el.xml in resources:

<?xml version="1.0" encoding="UTF-8"?>
<flow>
    <chain name="chain1">
        THEN(a, b, c)
    </chain>
</flow>

Spring will automatically load the rules file at startup.
