上幾篇文章主要講了《實戰項目：設計實現一個流程編排框架(分析)》《實戰項目：設計實現一個流程編排框架(設計》《實戰項目：設計實現一個流程編排框架(實現)》,今天主要做一個快速入門手冊。

Service-flow
微服務流程編排框架，支持方法節點、bean節點、條件節點（循環節點）、服務節點、子流程節點。
快速入門
依賴
版本按實際情況給定
<dependency>
<groupId>com.service.flow</groupId>
<artifactId>service-flow-spring-boot-starter</artifactId>
</dependency>
定義輸出參數DTO
需要繼承BaseInput
public class TestInput extends BaseInput
定義輸出參數DTO
需要繼承BaseOutPut
public class TestOutput extends BaseOutput
定義流程臨時變量
需要繼承BaseTemp
public class TestTemp extends BaseTemp
定義組件
@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;
}
......
}
流程定義
新增流程文件
在resources/flow下新建test.flow.yml
