第一步在專案pom.xml檔案中新增所需依賴
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.springboot.demo</groupId> <artifactId>springboot-activiti-demo</artifactId> <version>1.0.0</version> <packaging>war</packaging> <name>springboot-activiti-demo</name> <description>springboot-demo</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <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-data-jpa</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8081</port> <path>/activity</path> <systemProperties> <com.sun.management.jmxremote.port>4000</com.sun.management.jmxremote.port> </systemProperties> </configuration> </plugin> </plugins> </build> </project>
第二步:編寫示例介面和介面實現類
介面類(ActivityConsumerService.java)
package com.springboot.demo.service; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("/test") public interface ActivityConsumerService { /** * 流程demo * @return */ @RequestMapping(value="/activitiDemo",method=RequestMethod.GET) public boolean startActivityDemo(); }
介面實現類(ActivityConsumerServiceImpl.java)
package com.springboot.demo.service.impl; import java.util.HashMap; import java.util.List; import java.util.Map; import org.activiti.engine.RepositoryService; import org.activiti.engine.RuntimeService; import org.activiti.engine.TaskService; import org.activiti.engine.impl.persistence.entity.ExecutionEntity; import org.activiti.engine.task.Task; import org.activiti.engine.task.TaskQuery; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.springboot.demo.service.ActivityConsumerService; @Service("activityService") public class ActivityConsumerServiceImpl implements ActivityConsumerService { @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Autowired private RepositoryService repositoryService; @Override public boolean startActivityDemo() { System.out.println("method startActivityDemo begin...."); System.out.println( "呼叫流程儲存服務,查詢部署數量:" + repositoryService.createDeploymentQuery().count()); Map<String,Object> map = new HashMap<String,Object>(); map.put("apply","zhangsan"); map.put("approve","lisi"); //流程啟動 ExecutionEntity pi1 = (ExecutionEntity) runtimeService.startProcessInstanceByKey("leave",map); List<Task> tq=taskService.createTaskQuery().taskAssignee("zhangsan").list(); System.out.println(tq.size()); String assignee = "zhangsan";//當前任務辦理人 List<Task> tasks = taskService//與任務相關的Service .createTaskQuery()//建立一個任務查詢物件 .taskAssignee(assignee) .list(); if(tasks !=null && tasks.size()>0){ for(Task task:tasks){ System.out.println("任務ID:"+task.getId()); System.out.println("任務的辦理人:"+task.getAssignee()); System.out.println("任務名稱:"+task.getName()); System.out.println("任務的建立時間:"+task.getCreateTime()); System.out.println("流程例項ID:"+task.getProcessInstanceId()); System.out.println("#####################################"); } } System.out.println("method startActivityDemo end...."); return false; } }
第三步:在src/main/java/resources目錄下新建processes目錄,並在該目錄下新增一個業務流程檔案
MyProcess.bpmn:

專案目錄結構如下圖:
第四步:在mysql資料庫伺服器增加資料庫:activiti-demo
第五步:設定application.properties配置自己應用的相關資訊
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/activiti-demo?characterEncoding=utf8&useSSL=true
spring.datasource.username=root
spring.datasource.password=ROOT
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.show-sql=true
server.port=8081
server.context-path=/
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8
第六步:啟動應用後,在瀏覽器位址列輸入訪問地址:
http://localhost:8081/test/activitiDemo
