组件手动注册

对于组件来说，LiteFlow不光支持springboot/spring的扫描，还支持在规则文件里定义组件

除此之外，LiteFlow还支持代码式的组件注册，适用于一些特殊场景，比如代码中生成的动态代理类

假设有a,b两个组件

public class ACmp extends NodeComponent {
    @Override
    public void process() {
        System.out.println("ACmp executed!");
    }
}
public class BCmp extends NodeComponent {
    @Override
    public void process() {
        System.out.println("BCmp executed!");
    }
}

springboot环境

配置文件中一定要把parse-on-start设为false

liteflow.rule-source=config/flow.xml
liteflow.parse-on-start=false

Java代码

FlowBus.addNode("a", ACmp.class);
FlowBus.addNode("b", BCmp.class);
LiteflowResponse<DefaultSlot> response= flowExecutor.execute2Resp("chain1", "it's a request");

spring环境

<context:component-scan base-package="com.yomahub.flowtest.components" />
<bean id="springAware" class="com.yomahub.liteflow.util.SpringAware"/>
<bean class="com.yomahub.liteflow.spring.ComponentScaner"/>
<bean id="liteflowConfig" class="com.yomahub.liteflow.property.LiteflowConfig">
    <property name="ruleSource" value="config/flow.xml"/>
    <property name="parseOnStart" value="false"/>
</bean>
<bean id="flowExecutor" class="com.yomahub.liteflow.core.FlowExecutor">
    <property name="liteflowConfig" ref="liteflowConfig"/>
</bean>
<!-- 如果上述enableLog为false，下面这段也可以省略 -->
<bean class="com.yomahub.liteflow.monitor.MonitorBus">
    <property name="liteflowConfig" ref="liteflowConfig"/>
</bean>

Java代码

FlowBus.addNode("a", ACmp.class);
FlowBus.addNode("b", BCmp.class);
LiteflowResponse<DefaultSlot> response= flowExecutor.execute2Resp("chain1", "it's a request");
