Solon Flow Helloworld（通用流编排框架）

探索视频：

1、新建项目

可以用 Solon Initializr 生成一个模板项目。新建项目之后，添加依赖

 <dependency> <groupId>org.noear</groupId> <artifactId>solon-flow</artifactId> </dependency> 

2、添加配置

添加应用配置：

 solon.flow: - "classpath:flow/*.yml" 

添加流处理配置（支持 json 或 yml 格式），例： flow/demo1.chain.yml

 id: "c1" layout: - { id: "n1", type: "start", link: "n2"} - { id: "n2", type: "activity", link: "n3", task: "System.out.println(\"hello world!\");"} - { id: "n3", type: "end"}

3、代码应用

注解模式

 import org.noear.solon.annotation.Component; import org.noear.solon.annotation.Inject; import org.noear.solon.core.bean.LifecycleBean; import org.noear.solon.flow.FlowEngine; @Component public class DemoCom implements LifecycleBean { @Inject private FlowEngine flowEngine; @Override public void start() throws Throwable { flowEngine.eval("c1"); } } 

原生 Java 模式

 import org.noear.solon.flow.FlowEngine; FlowEngine engine = FlowEngine.newInstance(); //加载链配置 engine.load("classpath:flow/*"); //执行 engine.eval("c1");
