activiti实现节点自由跳转

 直接上代码:

接口:

package com.workflow.service;

import java.util.List;


public interface ProcessService {
    /**
     * 自由跳转
     * @param taskId 当前任务ID,必传输,考虑出现非会签的并行任务
     * @param targetTaskKey 目标节点ID,非任务ID
     */
     void freeJumpFlow(String taskId,String targetTaskKey);


}

实现类：

 @Override
    public void freeJumpFlow(String taskId, String targetTaskKey) {
        Task task=taskService.createTaskQuery().taskId(taskId).singleResult();
        if (task==null){
            //确定流程是否存在和是否在流转
            throw new RuntimeException("该任务不存在，无法执行该操作");
        }
//        List<Task> tasks=taskService.createTaskQuery().processInstanceId(task.getProcessInstanceId()).list();
        //获得当前流程的活动ID
        ExecutionQuery executionQuery =runtimeService.createExecutionQuery();
        Execution execution =executionQuery.executionId(task.getExecutionId()).sing
