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。
