Activiti多人会签，1/3的人同意则审批通过的实现

Activiti多人会签，1/3的人同意则审批通过的实现

第一步：配置流程

1. 配置审批通过的条件，如下，

线条上配置审批通过条件：${passCount/totalCount >=1/3}

线条上配置审批退回条件：${passCount/totalCount < 1/3}

 

2. 申请节点添加结束监听器

3. 配置该审批节点结束的条件

Sequential:false，false为并行执行，true为串行执行，此处要设置为并行

Collection: ${partyList}，用于执行该会签环节的参与人，此处使用partyList的流程变量

Element variable: party,此处表示的是每一个分支都有一个叫party的流程变量，和上方的assignee结合使用就可以决定该分支应该由谁执行

Completion condition:该节点的结束条件（该条件一定要配置，否则要等所有人都执行完才会结束该节点）

4. 为该审批节点添加创建时的监听器

二：代码部分

1. 申请节点结束时，设置下个审批节点的参与人

监听器内容如下，主要用于设置下个审批节点的参与人

package com.ylkj.base.flow.listener;

 

import java.util.ArrayList;

import java.util.List;

 

import org.activiti.engine.delegate.DelegateTask;

import org.activiti.engine.delegate.TaskListener;

 

public class MyCompeteistener implements TaskListener {

@Override

public void notify(DelegateTask arg0) {

      List<String> userList = new ArrayList<String>();

      userList.add("111");

      userList.add("222");

      userList.add("333");

      arg0.setVariable("partyList", userList);

}

}

 

2. 审批节点创建时的监听器，主要用于分配任务执行人

监听器内容如下：

package com.ylkj.base.flow.listener;

 

import org.activiti.engine.delegate.DelegateTask;

import org.activiti.engine.delegate.TaskListener;

/**

 * 节点创建监听器

 * 为节点设置处理人

 */

public class MutiGroupsListener implements TaskListener {

//节点完成的时候调用此监听器

@Override

public void notify(DelegateTask arg0) {

      //将通过人数，未通过人数，总数，重新置为0，退回的时候才能重新计算

      arg0.setVariable("passCount", "0");

      arg0.setVariable("totalCount", "0");

      arg0.setVariable("noPassCount", "0");

      //为每一个任务设置处理人

      String party = (String)arg0.getVariable("party");

     arg0.setAssignee(party);

}

}

3. 审批节点有人执行任务时，需要统计执行情况

/* (非 Javadoc)

* <p>Title: completeTask1</p>

* <p>Description: </p>

* @param procInstId 流程实例id

* @param taskId     任务id

* @param variables  流程变量

* @param passflag   审批同意标志（yes/no）

* @see com.ylkj.base.activiti.service.ActivitiService#completeTask1(java.lang.String, java.lang.String, java.util.Map, java.lang.String)

*/

     

public void completeTask1(String procInstId,String taskId, Map<String, Object> variables,String passflag) {

      //获取当前节点的task_def_key_,此段代码主要用于区分多个节点时，审批通过记录数与总数

      Task taskQuery = processEngine.getTaskService().createTaskQuery().taskId(taskId).singleResult();

      List<Task> tasks = processEngine.getTaskService().createTaskQuery().taskName(taskQuery.getName()).processInstanceId(procInstId).list();

     

      int passCount = 0;//审批同意人数

      int noPassCount = 0;//审批不同意人数

      int totalCount = 0;//任务总人数

      //当前的执行情况

      String tmpPassCount = processEngine.getRuntimeService().getVariable(procInstId, taskQuery.getTaskDefinitionKey()+"#passCount")+"";

      String tmpNoPassCount = processEngine.getRuntimeService().getVariable(procInstId, taskQuery.getTaskDefinitionKey()+"#noPassCount")+"";

      String tmpTotal = processEngine.getRuntimeService().getVariable(procInstId, taskQuery.getTaskDefinitionKey()+"#totalCount")+"";

     

      if(!tmpPassCount.equals("null") && !tmpPassCount.trim().equals("")){

           passCount = Integer.parseInt(tmpPassCount);

      }

     

      if(!tmpNoPassCount.equals("null") && !tmpNoPassCount.trim().equals("")){

           noPassCount = Integer.parseInt(tmpNoPassCount);

      }

     

      if(tmpTotal.equals("null") || tmpTotal.trim().equals("")){

           totalCount = tasks.size();

      } else if(!tmpTotal.equals("null") && !tmpTotal.trim().equals("")){

           totalCount = Integer.parseInt(tmpTotal);

      }

      for (Task tmp:tasks) {

         if(passflag.equals("yes") && tmp.getId().equals(taskId)){//选择通过则通过人数+1

               passCount++;

           }

          

           if(passflag.equals("no") && tmp.getId().equals(taskId)){//选择不通过则不通过人数+1

               noPassCount++;

           }

          

      }

      //变量回写记录

      variables.put("passCount", passCount);

      variables.put("noPassCount", noPassCount);

      variables.put("totalCount", totalCount);

      variables.put(taskQuery.getTaskDefinitionKey()+"#passCount", passCount);

      variables.put(taskQuery.getTaskDefinitionKey()+"#noPassCount", noPassCount);

      variables.put(taskQuery.getTaskDefinitionKey()+"#totalCount", totalCount);    

      processEngine.getTaskService().complete(taskId,variables);

}

4. 流程配置xml如下：
