## 1.下载acitiviti6 ##

官网慢的话，到百度网盘搜索

idea按住嗯actiBPM插件

## 2.创建boot项目 ##

依赖

resources下面创建processes文件夹，并且创建一个bpmn文件，可以使空的。

启动类

@SpringBootApplication(exclude = SecurityAutoConfiguration.class)
    public class DemoApplication {
        public static void main(String[] args) {
            SpringApplication.run(DemoApplication.class, args);
        }
    }

项目启动成功

数据源boot自动配置的，不需要自己配置  
流程引擎也自动有了，可以直接注入引擎的接口

@Autowired
    private RuntimeService runtimeService;
     
    @Autowired
    private TaskService taskService;
     
    @Autowired
    private IdentityService identityService;
     
    @Autowired
    private RepositoryService repositoryService;
     
    @Autowired
    private ProcessEngine processEngine;
     
    @Autowired
    private HistoryService historyService;

## 3.画流程图 ##

id必须用英文，名称可以用中文

复制出来，改为xml文件  
选择xml文件，右键选择show bpmn2.0 designer

选择export to file，存储到当前目录，为leave.png。等一会，才会显示出来

## 4.流程定义 ##

@RestController
    @RequestMapping("/test")
    public class TestController {
        @Autowired
        private RepositoryService repositoryService;
    
        @GetMapping("/deploy")
        public Object deploy() {
            DeploymentBuilder deployment = repositoryService.createDeployment();
    
            //图片必须指定
            Deployment test = deployment.name("test")
                    .addClasspathResource("processes/leave.bpmn")
                    .addClasspathResource("processes/leave.png")
                    .deploy();
            return test.getId();
        }
    }

设计三张表act\_re\_deployment，act\_re\_procdef，act\_ge\_bytearray
