整合SpringBoot + Vue + Camunda + bpmn.js实现工作流前后端部署(若依框架实现)
以下是一个简化的示例,展示如何在若依平台上使用Spring Boot、Vue和Camunda实现工作流前后端部署。
后端代码(Spring Boot)
@Configuration
public class CamundaConfig {
@Bean
public ProcessEngine processEngine() {
return ProcessEngineConfiguration
.createStandaloneInMemProcessEngineConfiguration()
.buildProcessEngine();
}
}
@RestController
public class WorkflowController {
@Autowired
private RepositoryService repositoryService;
@Autowired
private RuntimeService runtimeService;
// 部署流程定义
@PostMapping("/deploy")
public ResponseEntity<String> deploy(@RequestParam("file") MultipartFile file) {
repositoryService.createDeployment()
.addModelType("text/xml; charset=UTF-8")
.addZipInputStream(file.getInputStream())
.deploy();
return ResponseEntity.ok("流程定义部署成功");
}
// 启动流程实例
@PostMapping("/start")
public ResponseEntity<String> start(@RequestParam("key") String key) {
runtimeService.startProcessInstanceByKey(key);
return ResponseEntity.ok("流程实例启动成功");
}
// 其他工作流相关API
}
前端代码(Vue)
<!-- 上传BPMN文件的表单 -->
<template>
<div>
<input type="file" @change="uploadBpmn" />
</div>
</template>
<script>
export default {
methods: {
uploadBpmn(event) {
const file = event.target.files[0];
const formData = new FormData();
formData.append('file', file);
this.$http.post('/deploy', formData, {
headers: {
'Content-Type': 'multipart/form-data'
}
}).then(response => {
console.log(response.data);
}).catch(error => {
console.error(error);
});
}
}
}
</script>
配置文件
# application.properties
spring.datasource.url=jdbc:h2:mem:camunda-db;DB_CLOSE_DELAY=-1
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=update
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
spring.h2.console.settings.web-allow-others=true
以上代码提供了一个简单的例子,展示了如何在Spring Boot应用程序中集成Camunda,并通过REST API与Vue前端进行交互。这个例子仅包含了部署和启动流程的基本API,实际应用中还需要实现其他工作流相关的API。
