上几篇文章主要讲了《[实战项目：设计实现一个流程编排框架(分析)][Link 1]》《[实战项目：设计实现一个流程编排框架(设计][Link 2]》《[实战项目：设计实现一个流程编排框架(实现)][Link 3]》,今天主要做一个快速入门手册。

代码地址：https://github.com/itrickzhang/service-flow

# Service-flow #

微服务流程编排框架，支持方法节点、bean节点、条件节点（循环节点）、服务节点、子流程节点。

# 快速入门 #

## 依赖 ##

版本按实际情况给定

<dependency>
        <groupId>com.service.flow</groupId>
        <artifactId>service-flow-spring-boot-starter</artifactId>
     </dependency>

## 定义输出参数DTO ##

需要继承BaseInput

public class TestInput extends BaseInput

## 定义输出参数DTO ##

需要继承BaseOutPut

public class TestOutput extends BaseOutput

## 定义流程临时变量 ##

需要继承BaseTemp

public class TestTemp extends BaseTemp

## 定义组件 ##

@Component("testComponent")
    public class TestComponent {
    
         public TestOutput test1(TestInput test){
             TestOutput testOutput = new TestOutput();
             BeanUtils.copyProperties(test,testOutput);
             System.out.println("1111111111"+testOutput);
             return testOutput;
         }
    ......
    
    }

# 流程定义 #

## 新增流程文件 ##

在resources/flow下新建test.flow.yml

name: openAccount
    id: test
    desc: 条件执行
    input: com.service.flow.sample.common.model.TestInput
    output: com.service.flow.sample.common.model.TestOutput
    temp: com.service.flow.sample.common.model.TestTemp
    startNode: node1
    nodes:
      - node:
          id: node1
          name: methodInvoke
          component: com.service.flow.sample.common.component.TestComponent:test1
          desc: 单节点执行
          input: com.service.flow.sample.common.model.TestInput
          type: method
          next: node2
      - node:
          id: node2
          name: beanInvoke
          component: testComponent:test2
          desc: 单节点执行
          input: com.service.flow.sample.common.model.TestInput
          type: bean
          next: node3
      - node:
          id: node3
          name: conditionByAge
          component: age>20:node4,age<20:node5
          desc: 条件节点执行
          type: condition
      - node:
          id: node4
          name: beanInvoke
          component: testComponent:test4
          desc: bean节点执行
          input: com.service.flow.sample.common.model.TestInput
          type: bean
      - node:
          id: node5
          name: beanInvoke
          component: testComponent:test5
          desc: bean节点执行
          input: com.service.flow.sample.common.model.TestInput
          type: bean
          next: node6
      - node:
          id: node6
          name: serviceInvoke
          component: /test:post:testApplication
          desc: 服务节点
          input: com.service.flow.sample.common.model.TestInput
          type: service
          next: node7
      - node:
          id: node7
          name: subFlow
          component: test2
          desc: 子流程节点
          input: com.service.flow.sample.common.model.TestInput
          type: subflow
