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 非注解方式

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

注解方式

name: addCount
id: test6
desc: 方法节点执行
input: Test1Input
output: Test1Output
temp: Test1Temp
startNode: methodNode1
nodes:
    - node:
          id: methodNode1
          name: methodNode1
          component: count
          desc: 数量+1
          input: Test1Input
          type: method
          next: methodNode2
    - node:
          id: methodNode2
          name: methodNode2
          component: count
          desc: 数量+1
          input: Test1Input
          type: method
          next: methodNode3
    - node:
          id: methodNode3
          name: methodNode3
          component: count
          desc: 数量+1
          input: Test1Input
          type: method
