springboot集成activiti6
1、导入pom依赖，因为我项目中集成的是mybatisplus，所以要排除activiti自带的mybatis
<!--activiti基础包-->
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring-boot-starter-basic</artifactId>
<version>6.0.0</version>
<exclusions>
<exclusion>
<artifactId>mybatis</artifactId>
<groupId>org.mybatis</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-json-converter</artifactId>
<version>6.0.0</version>
</dependency>
<dependency>
<groupId>org.apache.xmlgraphics</groupId>
<artifactId>batik-transcoder</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>org.apache.xmlgraphics</groupId>
<artifactId>batik-codec</artifactId>
<version>1.7</version>
</dependency>
2、排除activiti自带的安全谁
@SpringBootApplication(exclude = SecurityAutoConfiguration.class) @EnableScheduling @Slf4j public class RenrenApplication { public static void main(String[] args) { //SpringApplication. SpringApplication.run(RenrenApplication.class, args); } }
3、设置流程定义，bpmn，这个是xml文件，可以直接该后缀名为bpmn

其中最重要的是实现类
其中test6、test7执行的效果图如下
/** * 通过实例id，查看改实例处置流程，时间线 * */ @RequestMapping("/test6") public void taskHistory(){ leaveApplyService.taskHistory(); } /** * 已经执行的历史记录,通过图片方式来查看实例执行到哪一步 * */ @RequestMapping("/test7") public void activityTaskHistory(HttpServletResponse response){ leaveApplyService.activityTaskHistory(response); }
test6: 查看实例执行历史记录
test7: 查看实例执行的节点，目前是执行到销假的步骤
