1.第一步添加bpmn文件得插件，不然没法查看和编辑bpmn文件，添加插件的方法各自百度即可，很简单
2.安装好bpmn插件后开始新建bpmn文件，也就是画流程图
一般是在代码中进行指定流程审批人的，我这里只做入门案例
3.添加pom依赖
这里包含了在线设计流程图的相关依赖，在下一篇会写出来，项目中一般都是在前端在线设计；所以直接放上去也没事
<?xml version="1.0" encoding="UTF-8"?>4.0.0 org.springframework.boot spring-boot-starter-parent 2.2.0.RELEASE com springboot_activiti 0.0.1-SNAPSHOT springboot_activiti Demo project for Spring Boot 2.2.0.RELEASE UTF-8 UTF-8 1.8 6.0.0 org.activiti activiti-engine ${activiti.version} org.activiti activiti-spring ${activiti.version} org.codehaus.jackson jackson-core-asl org.slf4j slf4j-log4j12 spring-context org.springframework spring-jdbc org.springframework spring-tx org.springframework spring-orm org.springframework spring-beans org.springframework mybatis org.mybatis activation javax.activation org.activiti activiti-spring-boot-starter-basic ${activiti.version} org.activiti activiti-common-rest ${activiti.version} org.activiti activiti-modeler 5.22.0 spring-beans org.springframework spring-context org.springframework spring-core org.springframework spring-tx org.springframework spring-web org.springframework spring-security-config org.springframework.security spring-security-core org.springframework.security spring-security-crypto org.springframework.security spring-security-web org.springframework.security spring-webmvc org.springframework activation javax.activation commons-io commons-io org.springframework.boot spring-boot-autoconfigure ${springboot.version} org.springframework.boot spring-boot-starter-tomcat org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-starter-thymeleaf org.springframework.boot spring-boot-starter-web commons-io commons-io 2.3 com.fasterxml.jackson.core jackson-core 2.10.0 org.springframework.boot spring-boot-starter-data-jpa MySQL mysql-connector-java runtime org.junit.jupiter junit-jupiter-api RELEASE compile org.springframework.boot spring-boot-maven-plugin org.apache.tomcat.maven tomcat7-maven-plugin 8081 /activity 4000
4.yml文件
这里采用的数据库还是mysql
这里有个需要注意的地方，springboot2.2中的driver-class-name值变了，不是以前的那个了，不然会报错
spring:
datasource:
url: jdbc:mysql://localhost:3307/t2?useUnicode=true&characterEncoding=utf-8&useSSL=false&autoReconnect=true&serverTimezone=UTC
username: root
password: root
driver-class-name: com.mysql.cj.jdbc.Driver
activiti:
# 自动部署验证设置:true-开启（默认）、false-关闭
check-process-definitions: false
#自动部署文件路径后缀
# process-definition-location-prefix: classpath:/processes/
# process-definition-location-suffixes:
# - **.bpmn
# - **.bpmn20.xml
server:
port: 8082
5.配置已经好了，下面开始写代码了，只是初步写了一些新建流程，正常提交流程，直接结束流程，以及查询待办的案例，细节还需要各自自己去调试学习
controller
package com.springboot_activiti.controller;
import com.springboot_activiti.service.ActivityConsumerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/activiti")
public class ActivitiController {
@Autowired
private ActivityConsumerService activityConsumerService;
/**
* 注册流程
* @return
*/
@RequestMapping("/createDeployment")
public Boolean createDeployment(){
return activityConsumerService.createDeployment();
}
/**
* 启动流程
* @return
*/
@RequestMapping("/startActivityDemo")
public Boolean startActivityDemo(){
return activityConsumerService.startActivityDemo("test01");
}
/**
* 获取待办
* @return
*/
@RequestMapping("/getTaskList")
public boolean getTaskList(){
return activityConsumerService.getTaskList();
}
/**
* 提交
* @param taskId
* @return
*/
@RequestMapping("/complete")
public boolean complete(String taskId){
return activityConsumerService.complete(taskId);
}
/**
* 根据流程id直接结束流程
* @paramru
* @return
*/
@RequestMapping("/deleteProcessInstance")
public boolean deleteProcessInstance(String runId){
return activityConsumerService.deleteProcessInstance(runId);
}
}service
package com.springboot_activiti.service;
public interface ActivityConsumerService {
boolean createDeployment();
boolean startActivityDemo(String key);
boolean getTaskList();
boolean complete(String taskId);
boolean deleteProcessInstance(String runId);
}实现类
package com.springboot_activiti.service;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("activityService")
public class ActivityConsumerServiceImpl implements ActivityConsumerService {
@Autowired
private RuntimeService runtimeService;
@Autowired
private TaskService taskService;
@Autowired
private RepositoryService repositoryService;
/**
* 注册一个流程
* @return
*/
@Override
public boolean createDeployment() {
DeploymentBuilder builder=repositoryService.createDeployment();
builder.addClasspathResource("test01.bpmn");
builder.deploy();
return true;
}
/**
* 查询待办
* @return
*/
public boolean getTaskList(){
//获取待办的一些信息，这里可以传入需要查询的用户，
//我这里查询的所有待办
List tasks = taskService.createTaskQuery().list();
for (Task t:tasks) {
System.out.println(t.getCreateTime());
System.out.println(t.getId());
System.out.println(t.getName());
System.out.println(t.getProcessInstanceId());
System.out.println(t.getTaskDefinitionKey());
System.out.println(t.getParentTaskId());
}
return true;
}
/**
* 根据流程key开启一个流程
* @param key
* @return
*/
@Override
public boolean startActivityDemo(String key) {
ProcessInstance test01 = runtimeService.startProcessInstanceByKey(key);
String id = test01.getId();
System.out.println("流程id="+id);
/* */
/* String assignee = "abc";*/
return true;
}
/**
* 根据任务id提交任务
* @param taskId
* @return
*/
@Override
public boolean complete(String taskId){
taskService.complete(taskId);
return true;
}
/**
* 根据流程id直接结束流程
* @param runId
* @return
*/
@Override
public boolean deleteProcessInstance(String runId){
runtimeService.deleteProcessInstance(runId,"结束");
return true;
}
} 启动类，这里存在一个在线视图设计的验证处理，
package com.springboot_activiti;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@ComponentScan("com")
@SpringBootApplication
@EnableAutoConfiguration(exclude = {
org.activiti.spring.boot.SecurityAutoConfiguration.class
})
public class SpringbootActivitiApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootActivitiApplication.class, args);
}
}所有的代码已经写好了
备注说明：
项目启动会新建28张表，各自代表的含义自行百度把
因为我的数据都是直接在流程图bpmn文件里面写好的，实际中肯定是在代码里面指定的
首先访问注册流程
启动流程（会返回一个流程id）
查看待办就可以获取相关的信息了
正常提交任务，会审批到下一节点（查看待办可以得到任务id）
直接结束流程（非正常结束，启动流程的id传入即可）
请求案例
查询待办
启动流程
