业务流程可视化-让你的流程图"Run"起来(5.SpringBoot集成&微服务编排)
前言
前面的系列文章里，介绍了ladybugflow的业务可视化的设计以及常见场景的使用方法。
感谢大家对项目的关注。
本篇文章介绍一下基于ladybugflow的微服务编排场景及使用方法。
1. 业务场景
和上一篇文章使用同样的酒店预定业务场景，本篇文章我们将它继承到SpringBoot中。
如下图所示：
不同的是，这里我们将【查询用户信息】和【查询酒店信息】业务作为远程微服务调用，项目架构如下图所示：
- 查询酒店信息节点调用远程微服务App2的查询酒店信息接口
- 查询用户信息节点调用远程微服务App3的查询用户信息接口
- 在下单节点中将用户信息和酒店信息输出到日志中。
2. 与SpringBoot的集成
接下来我们将微服务App1,App2,App3做成3个SpringBoot工程。
App2:酒店信息查询微服务
我们创建一个SpringBoot项目，添加如下接口：
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:用户信息查询微服务
我们创建一个SpringBoot项目，添加如下接口：
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:酒店预定微服务
我们创建一个SpringBoot项目，工程结构如下：
加入ladybugflow依赖，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()
}然后分别实现酒店预定的Controler,Service和Flow层代码，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("启动开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("启动结束");
}
@Node(label = "查询用户信息")
public void processSearchUser() throws InterruptedException {
System.out.println("查询用户信息开始 （模拟业务等待3秒）");
userInfo = userInfoNode.getUser(456);
System.out.println("查询用户信息结束");
}
@Node(label = "查询酒店信息")
public void processSearchHotel() throws InterruptedException {
System.out.println("查询酒店信息开始 （模拟业务等待3秒）");
hotelInfo = hotelInfoNode.getHotel(123);
System.out.println("查询酒店信息结束");
}
@Node(label = "下单")
public void processOrder() throws InterruptedException {
System.out.println("下单开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("下单结束");
}
@Node(label = "下单成功")
public void processSuccess() throws InterruptedException {
System.out.println("下单成功开始 （模拟业务等待3秒）");
Thread.sleep(3000);
System.out.println("下单成功结束");
System.out.println("userInfo:"+userInfo);
System.out.println("hotelInfo:"+hotelInfo);
}
}

3. 运行
启动微服务App1,App2,App3，
然后再浏览器输入 http://localhost:8080/book_hotel
可以看到正常结束日志

4. 业务流程变更
ladybugflow的优点是将业务流程与业务代码分开管理，从而可以轻松的应对业务流程变更而不需要修改代码。
比如将业务流程修改为如下图所示的串行执行的时候
步骤1：将json文件拷贝到可视化工具中，生成流程图
步骤2：修改流程图
步骤3：更新json
步骤4：将更新后的json替换到工程中
