基於LadybugFlow的微服務編排(1.SpringBoot整合)
2022-08-04 15:01:29
前言
前面的系列文章裡，介紹了ladybugflow的業務視覺化的設計以及常見場景的使用方法。
感謝大家對專案的關注。
本篇文章介紹一下基於ladybugflow的微服務編排場景及使用方法。
1. 業務場景
和上一篇文章使用同樣的酒店預定業務場景，本篇文章我們將它繼承到SpringBoot中。
如下圖所示：
不同的是，這裡我們將【查詢使用者資訊】和【查詢酒店資訊】業務作為遠端微服務呼叫，專案架構如下圖所示：
- 查詢酒店資訊節點呼叫遠端微服務App2的查詢酒店資訊介面
- 查詢使用者資訊節點呼叫遠端微服務App3的查詢使用者資訊介面
- 在下單節點中將使用者資訊和酒店資訊輸出到紀錄檔中。
2. 與SpringBoot的整合
接下來我們將微服務App1,App2,App3做成3個SpringBoot工程。
App2:酒店資訊查詢微服務
我們建立一個SpringBoot專案，新增如下介面：
http://localhost:8082/getHotel?hotel_id=XXX
@Controller
public class HotelInfoController {
@RequestMapping(method = RequestMethod.GET, value = "/getHotel")
@ResponseBody
public String getHotelInfo(@RequestParam("hotel_id") int hotelId) {
return "HOTEL:"+hotelId;
}
}
App3:使用者資訊查詢微服務
我們建立一個SpringBoot專案，新增如下介面：
http://localhost:8083/getUser?user_id=XXX
@Controller
public class UserInfoController {
@RequestMapping(method = RequestMethod.GET, value = "/getUser")
@ResponseBody
public String getUserInfo(@RequestParam("user_id") int userId) {
return "USER:"+userId;
}
}
App1:酒店預定微服務
我們建立一個SpringBoot專案，工程結構如下：
加入ladybugflow依賴，如下:
build.gradle
plugins {
id 'org.springframework.boot' version '2.7.2'
id 'io.spring.dependency-management' version '1.0.12.RELEASE'
id 'java'
}
group = 'nobuglady'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
}
ext {
set('springCloudVersion', "2021.0.3")
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.cloud:spring-cloud-starter-openfeign'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
implementation 'io.github.nobuglady:ladybugflow:0.0.6'
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
tasks.named('test') {
useJUnitPlatform()
}然後分別實現酒店預定的Controler,Service和Flow層程式碼，如下：
LadybugflowDemoMicroservice1Application.java
@SpringBootApplication
@EnableFeignClients
public class LadybugflowDemoMicroservice1Application {
public static void main(String[] args) {
SpringApplication.run(LadybugflowDemoMicroservice1Application.class, args);
}
@PreDestroy
public void onExit() {
FlowStarter.shutdown();
}
}
BookHotelController.java
@Controller
public class BookHotelController {
@Autowired
private BookHotelService bookHotelService;
@RequestMapping(value = "/book_hotel", method = RequestMethod.GET)
@ResponseBody
public String bookHotel() {
bookHotelService.bookHotel();
return "ok";
}
}
BookHotelService.java
@Service
public class BookHotelService {
@Autowired
private BookHotelFlow bookHotelFlow;
public void bookHotel() {
bookHotelFlow.startFlow(false);
}
}
BookHotelFlow.java
@Component
public class BookHotelFlow extends FlowRunner{
@Autowired
private HotelInfoNode hotelInfoNode;
@Autowired
private UserInfoNode userInfoNode;
private String userInfo;
private String hotelInfo;
@Node(label = "start")
public void processStart() throws InterruptedException {
System.out.println("啟動開始 （模擬業務等待3秒）");
Thread.sleep(3000);
System.out.println("啟動結束");
}
@Node(label = "查詢使用者資訊")
public void processSearchUser() throws InterruptedException {
System.out.println("查詢使用者資訊開始 （模擬業務等待3秒）");
userInfo = userInfoNode.getUser(456);
System.out.println("查詢使用者資訊結束");
}
@Node(label = "查詢酒店資訊")
public void processSearchHotel() throws InterruptedException {
System.out.println("查詢酒店資訊開始 （模擬業務等待3秒）");
hotelInfo = hotelInfoNode.getHotel(123);
System.out.println("查詢酒店資訊結束");
}
@Node(label = "下單")
public void processOrder() throws InterruptedException {
System.out.println("下單開始 （模擬業務等待3秒）");
Thread.sleep(3000);
System.out.println("下單結束");
}
@Node(label = "下單成功")
public void processSuccess() throws InterruptedException {
System.out.println("下單成功開始 （模擬業務等待3秒）");
Thread.sleep(3000);
System.out.println("下單成功結束");
System.out.println("userInfo:"+userInfo);
System.out.println("hotelInfo:"+hotelInfo);
}
}

3. 執行
啟動微服務App1,App2,App3，
然後再瀏覽器輸入 http://localhost:8080/book_hotel
可以看到正常結束紀錄檔

4. 業務流程變更
ladybugflow的優點是將業務流程與業務程式碼分開管理，從而可以輕鬆的應對業務流程變更而不需要修改程式碼。
比如將業務流程修改為如下圖所示的序列執行的時候
步驟1：將json檔案拷貝到視覺化工具中，生成流程圖
步驟2：修改流程圖
步驟3：更新json
步驟4：將更新後的json替換到工程中
