activiti6使用

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

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.3.RELEASE</version> </parent> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.47</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-basic</artifactId> <version>6.0.0</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.1</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>

配置文件 application.yml

spring: profiles: active: dev server: port: 9005

application-dev.yml

spring: datasource: url: jdbc:mysql://localhost:3306/activiti?characterEncoding=utf-8&useSSL=false&useUnicode=true&zeroDateTimeBehavior=convertToNull username: root password: 123456 driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20 hikari.minimum-idle: 5 hikari.maximum-pool-size: 150 hikari.connection-test-query: SELECT 1 hikari.max-lifetime: 1800000 hikari.connection-timeout: 30000 # 空闲连接存活最大时间，默认600000（10分钟） hikari.idle-timeout: 1800000 activiti: check-process-definitions: false #自动检查、部署流程定义文件 database-schema-update: false #自动更新数据库结构 #流程定义文件存放目录 process-definition-location-prefix: classpath:/processes/ #process-definition-location-suffixes: #流程文件格式 history-level: full

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 查看-图像，选择bytes列，即可看到图片
