springboot服务端
在Spring Boot中使用Camunda外部任务客户端,可以通过以下步骤实现:
1. 添加Camunda依赖
在pom.xml文件中添加以下依赖:
```
<dependency>
<groupId>org.camunda.bpm.springboot</groupId>
<artifactId>camunda-bpm-spring-boot-starter</artifactId>
<version>${camunda.version}</version>
</dependency>
<dependency>
<groupId>org.camunda.bpm.client</groupId>
<artifactId>camunda-bpm-client</artifactId>
<version>${camunda.version}</version>
</dependency>
```
2. 配置Camunda客户端
在application.properties文件中添加以下配置:
```
camunda.bpm.client.bootstrap.servers=yourCamundaServerUrl
camunda.bpm.client.worker.id=yourWorkerId
camunda.bpm.client.topic-name=yourTopicName
camunda.bpm.client.auto-manage-embedded-engine=true
```
3. 创建客户端
创建一个类来实例化Camunda客户端:
```
@Configuration
public class CamundaClientConfig {
@Value("${camunda.bpm.client.bootstrap.servers}")
private String camundaUrl;
@Value("${camunda.bpm.client.worker.id}")
private String workerId;
@Value("${camunda.bpm.client.topic-name}")
private String topicName;
@Bean
public ExternalTaskClient externalTaskClient() {
return ExternalTaskClient.create()
.baseUrl(camundaUrl)
.asyncResponseTimeout(1000)
.workerId(workerId)
.maxTasks(1)
.lockDuration(1000)
.build();
}
}
```
4. 处理外部任务
实现外部任务处理逻辑:
```
@Component
public class MyExternalTaskHandler implements ExternalTaskHandler {
@Override
public void execute(ExternalTask task, ExternalTaskService service) {
// 处理外部任务逻辑
}
}
```
5. 订阅主题
在应用程序中订阅主题:
```
@Autowired
private ExternalTaskClient externalTaskClient;
@PostConstruct
public void subscribeToTopic() {
externalTaskClient.subscribe(topicName)
.handler(myExternalTaskHandler)
.open();
}
```
以上就是在Spring Boot中使用Camunda外部任务客户端的步骤。
