同步操作将从 秋天的童话/springboot-flowable 强制同步,此操作会覆盖自 Fork 仓库以来所做的任何修改,且无法恢复!!!
确定后同步将在后台操作,完成时将刷新页面,请耐心等待。
springboot-flowable 快速开发工作流
springboot + flowable + modeler + idm
springboot version : 2.1.5
flowable version : 6.4.0
==注意:== 版本需于数据库 act_ge_property 相同
需要先登录 http://127.0.0.1:8080/expense/idm/index.html
account: admin
pwd : test 再访问: http://127.0.0.1:8080/expense 创建设计器

这样操作后,flowable与springBoot的整个就完成了!
然后就可以运行了,初次运行时flowable会将自动执行flowable中的初始化脚本完成工作流所需要的数据表的建立,如果指定的数据库中还未创建过flowable的相关数据表的话。

其中的两个代理类为:
import org.flowable.engine.delegate.TaskListener;
import org.flowable.task.service.delegate.DelegateTask;
public class ManagerTaskHandler implements TaskListener {
@Override
public void notify(DelegateTask delegateTask) {
delegateTask.setAssignee("经理");
}
}
public class BossTaskHandler implements TaskListener {
@Override
public void notify(DelegateTask delegateTask) {
delegateTask.setAssignee("老板");
}
}
为了方便这里通过一个controller来完成此DEMO的快速编写
@Controller
public class ExpenseController {
@Autowired
private RuntimeService runtimeService;
@Autowired
private TaskService taskService;
@Autowired
private RepositoryService repositoryService;
@Autowired
private ProcessEngine processEngine;
/***************此处为业务代码******************/
}
/**
* 添加报销
*
* @param userId 用户Id
* @param money 报销金额
* @param descption 描述
*/
@RequestMapping(value = "add")
@ResponseBody
public String addExpense(String userId, Integer money, String descption) {
//启动流程
HashMap<String, Object> map = new HashMap<>();
map.put("taskUser", userId);
map.put("money", money);
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("Expense", map);
return "提交成功.流程Id为:" + processInstance.getId();
}
/**
* 获取审批管理列表
*/
@RequestMapping(value = "/list")
@ResponseBody
public Object list(String userId) {
List<Task> tasks = taskService.createTaskQuery().taskAssignee(userId).orderByTaskCreateTime().desc().list();
for (Task task : tasks) {
System.out.println(task.toString());
}
return tasks.toArray().toString();
}
/**

*/
@RequestMapping(value = "apply")
@ResponseBody
public String apply(String taskId) {
Task task = taskService.createTaskQuery().taskId(taskId).singleResult();
if (task == null) {
throw new RuntimeException("流程不存在");
}
//通过审核
HashMap<String, Object> map = new HashMap<>();
map.put("outcome", "通过");
taskService.complete(taskId, map);
return "processed ok!";
}
/**

@ResponseBody
@RequestMapping(value = "reject")
public String reject(String taskId) {

}
/**

*/
@RequestMapping(value = "processDiagram")
public void genProcessDiagram(HttpServletResponse httpServletResponse, String processId) throws Exception {
ProcessInstance pi = runtimeService.createProcessInstanceQuery().processInstanceId(processId).singleResult();
//流程走完的不显示图
if (pi == null) {
return;
}
Task task = taskService.createTaskQuery().processInstanceId(pi.getId()).singleResult();
//使用流程实例ID,查询正在执行的执行对象表,返回流程实例对象
String InstanceId = task.getProcessInstanceId();
List<Execution> executions = runtimeService
.createExecutionQuery()
.processInstanceId(InstanceId)
.list();
//得到正在执行的Activity的Id
List<String> activityIds = new ArrayList<>();
List<String> flows = new ArrayList<>();
for (Execution exe : executions) {
List<String> ids = runtimeService.getActiveActivityIds(exe.getId());
activityIds.addAll(ids);
}
//获取流程图
BpmnModel bpmnModel = repositoryService.getBpmnModel(pi.getProcessDefinitionId());
ProcessEngineConfiguration engconf = processEngine.getProcessEngineConfiguration();
ProcessDiagramGenerator diagramGenerator = engconf.getProcessDiagramGenerator();
InputStream in = diagramGenerator.generateDiagram(bpmnModel, "png", activityIds, flows, engconf.getActivityFontName(), engconf.getLabelFontName(), engconf.getAnnotationFontName(), engconf.getClassLoader(), 1.0);
OutputStream out = null;
byte[] buf = new byte[1024];
int legth = 0;
try {
out = httpServletResponse.getOutputStream();
while ((legth = in.read(buf)) != -1) {
out.write(buf, 0, legth);
}
} finally {
if (in != null) {
in.close();
}
if (out != null) {
out.close();
}
}
}
通过传入流程ID生成当前流程的流程图给前端,如果流程中使用到中文且生成的图片是乱码的,则需要进配置下字体:
/**
* @author haiyangp
* date: 2018/4/7
* desc: flowable配置----为放置生成的流程图中中文乱码
*/
@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
@Override
public void configure(SpringProcessEngineConfiguration engineConfiguration) {
engineConfiguration.setActivityFontName("宋体");
engineConfiguration.setLabelFontName("宋体");
engineConfiguration.setAnnotationFontName("宋体");
}
}
1.先启动好此项目,然后创建一个流程:
访问:http://localhost:8080/expense/add?userId=123&money=123321
返回:提交成功.流程Id为:2501
2.查询待办列表:
访问:http://localhost:8080/expense/list?userId=123
输出:Task[id=2507, name=出差报销]
3.同意:
==注意 : 带的是taskid==
访问:http://localhost:8080/expense/apply?taskId=2507
返回:processed ok!
4.生成流程图:
访问: http://localhost:8080/expense/processDiagram?processId=2501
